UPDATE BY METEOROLOGIST MATT HAMMER AT 2:00PM ON MARCH 9TH, 2017Good afternoon! It is certainly tough to fathom the return of winter in a big way as we look to tomorrow and the weekend when we are enjoying more warm temps today! However, that's exactly what's going to happen. We've also seen an enhanced risk for the spread of wildfires today due to low humidity levels and our strong, gusty winds.We have a nuisance snow on the way for tomorrow and there is still the chance for another winter storm early next week.So, let's go over the latest.
We have nice, dry sunshine over Long Island for now and we can see some snow and rain showers off to the West for now.A WINTER WEATHER ADVISORY is in effect from late tonight through early afternoon tomorrow. We'll have some rain/mix develop overnight. We do not have cold air locked into place right now. So, without that "prime" environment to support snow already in place, we'll start off in the upper 30s to near 40, with some rain/mix transitioning to snow by around daybreak or shortly before then tomorrow.As we go through March, while we can and do see snow, it gets more difficult for that snow to stick to warmer surfaces unless we have a period of moderate to heavy snow to help drop those surface temperatures. Tomorrow, we should see several hours of that moderate snow. If this storm was happening in January, we'd likely be looking at higher snow totals.Take a look at the futurecast images below to get a better idea at our upcoming winter storm for tomorrow. Just simply use the arrows at the right of each image to advance the graphic...Clouds will increase this evening and tonight, but look at our nice, comfortable evening temperatures...Overnight we'll see some rain to mix to eventually all snow early Friday morning. Roads will be wet to start, but will get sloppy throughout Friday.Light to moderate snow Friday morning...temps low to mid 30's...slightly colder temps out East could make things more icy to start there...Snow continues late Friday morning...Snow begins to taper off to scattered snow showers Friday afternoon...Drying out and cleaning up Friday evening...
1 of 6So, by the time the snow ends, we're looking at this in terms of snow totals:We may have to make slight adjustments to this this evening, but this should be close. It's tough, especially without a good supply of colder air, to get really high snow totals out of this. That being said, 2-5" of snow will be a nuisance and create sloppy and tricky travel on Friday. Highest snow amounts will be seen on grassy and colder surfaces and snow will be compacting a bit through the day.Until then...enjoy this afternoon and evening!The worst part about today = the wind - gusting 30-40 mph
Add CaptionOvernight...rain/mix changes to all snow by early Friday morning. Slick and icy roads possible through Friday...Over the next seven days...
Winter is certainly back through next week. VERY COLD air will be here from Friday night through the weekend. Watch for areas of ice. Wind chills on Saturday will be in the single digits to the teens. WE SPRING FORWARD Saturday night and lose an hour of sleep, but gain that extra hour of daylight!Yes, we are all still watching the potential for a more significant storm around the Tuesday time frame of next week, but it is still too early for any specifics on that.Have a great evening!Be sure to check Bill Korbel's updated evening forecast on News 12 Long Island starting at 5pm.- Matt Hammer
UPDATE BY METEOROLOGIST MATT HAMMER AT 10:30AM ON FEBRUARY 18TH, 2017Happy Saturday everyone! We'll keep this brief because the weather is very much cooperating this weekend. We are seeing gorgeous conditions all across Long Island today. If you happen to take a weather related photo be sure to send it my way on social media - thanks!Take a look at our weather headlines for this weekend:
We have nice, dry weather in control across much of the northeast today. We'll see some fair-weather clouds around, but that's it.Our morning low temperatures were COLD, but actually close to the average of around 26 in most spots. These temps are the coldest we'll see all weekend!FUTURE WEATHER MAP for the middle of this afternoon shows mainly sunny skies and highs in the upper 40s to low 50s...normal high is 41.
By later tonight and into early Sunday, we'll see some more clouds overhead, but it stays dry. Lows overnight will be around the upper 30s...Then, get ready for an even warmer day tomorrow! Mostly sunny skies develop again with highs in the upper 50s. The exception being the east end, but it will still be well above average there too.
To RECAP:...and here's a check of water conditions today:
Over the next seven days we will see mainly dry weather. Also, mostly above average temperatures. The chilliest weather will be Monday and Tuesday. A few rain showers are possible Wednesday and then we have a shot at some steadier rain for the start of next weekend.Have a great day!- Matt HammerFacebook: http://www.facebook.com/MattHammer12Twitter: http://www.twitter.com/MattHammer12Instagram: @MattHammer619
UPDATE BY METEOROLOGIST MATT HAMMER ON FEBRUARY 11TH 2017 AT 3:00PM
UPDATE: 3:45PM - Shortly after this post, not to my surprise, the National Weather Service issued a WINTER WEATHER ADVISORY for LONG ISLAND from 2AM Sunday until 12 NOON...for a bit of snow and sleet accumulation as well as the chance for an icy mix and freezing rain...roads likely very dangerous tomorrow morning...the original post follows below...I hope everyone is having a good start to the weekend. We saw mostly cloudy skies today and we have some wet and wintry weather on the way to discuss.I talked about a lot of this on Facebook this morning (www.facebook.com/MattHammer12) if you'd like to see a video version. Here, you can look at some of those graphics and more in addition to getting full details on the next seven days.So, as we go into tonight...skies will remain mainly cloudy and it'll be dry for much of the night. As we look towards early Sunday morning, that's when some big changes arrive.After topping off above average in the mid 40s this afternoon, eventually overnight temperatures will be falling back to around freezing. This is very important because as our next system moves in tomorrow morning, it will begin as wintry weather. This begins to take place well after midnight though. So, any evening plans tonight will be just fine.I'll show you a few futurecast images below. Notice the temperatures. Around 4am the wet and wintry weather will be closing on into Long Island with temperatures likely in the low 30s.By mid-morning, we are watching the chance for some problems. If we keep the colder air in place for a little while (...and I think we do...), we are looking at least a brief period of snow/wintry mix and the possibility of freezing rain. Basically a sloppy, slushy, potentially icy mess before plain rain. It would not take much to create some very slippery travel for tomorrow morning. It's a close call and especially the North Shore could see up to an inch or two of slushy wet snow before a changeover. We'll be watching this closely tonight and tomorrow morning. Roads will likely be very messy to start the day tomorrow.We eventually go over to a plain, cold rain which will likely be moderate to heavy at times. The rain in conjunction with melting snow will create big puddles and may cause some minor issues near poor drainage areas. Temperatures barely make it to 40 tomorrow.By late Sunday night into Monday morning ,we are still seeing some showers and it does get a bit more complicated... :)This is all a part of what's going to become a major blizzard for areas in New England NORTH OF LONG ISLAND. We get the sloppy mess on Sunday, followed by increasing winds and very windy conditions Sunday night into Monday. Wind gusts easily 40-50mph with a few higher gusts possible. You can see a map of the storm below by early Monday morning. The lines you see indicate a strong wind over the northeast and Long Island on the backside of the storm out of the northwest. This is a colder wind and will help bring some colder air...and potentially some snow showers back in the picture for the first part of Monday. The best chance for any snow will be east on Monday and computer models are suggesting a coating to an inch or two at most right now for that.Potential Light Accumulation Monday morning from the European model (1 to 2")Above you'll see the potential light accumulation projected lighter than the EURO on the North American Mesoscale Forecast System (NAM) model - around a coating to one-half inch on this projection. At the end of the day...it is likely to see a light accumulation and a slick commute Monday morning....after a sloppy Sunday.So, to recap and talk briefly about the next seven days...Tonight - dry, fine, becoming colder.Early Sunday - snow/wintry mix/rain moves in. We watch temps and precip closely for any icy, messy travel.Sunday Midday - a cold rain - it's breezy and becoming windier late.Sunday Night - showers, becoming very windy.Monday - Very windy with the chance for some morning snow in spots.Tuesday - dry and sunny.Wednesday - a clipper system passes to our north. Perhaps some scattered snow showers.Thursday - You may read online or see on social media people talking about a big storm for Thursday. As of today, that storm is shown offshore. This could change and we really won't start to have a good idea on its whereabouts until Monday.Feel free to reach out to me on Facebook, Twitter or Instagram and have a great Saturday! I will update quickly on those pages before sleep tonight and be back on-air at 7AM with any potential issues tomorrow morning.- Matt HammerFacebook: www.facebook.com/MattHammer12Twitter: www.twitter.com/MattHammer12Instagram: @MattHammer619
UPDATED BY METEOROLOGSIT RICH HOFFMAN FEBRUARY 7TH 2017 AT 630AM
Going to be a fun next 60 hours. Chance for record highs and then 12 hours later, breaking out the shovels.
On and off rain today one batch this morning and another early afternoon, looks like around quarter of an inch or rain.
Warm for Wednesday… and then track of coastal storm is important – looks like we are on the northern edge so any shift in track will change snow totals.
Tracking coastal storm - Most of the Major forecast models call for a moderate snowfall 3 to 8 inches. As we know with all storms track is very important. The storm will be fast moving and we have a high near Hudson bay that could suppress the south to the south. These would lower snow amounts. Much better idea tonight when the energy gets closer to the East Coast.
TODAY: Areas of Fog and drizzle. Cloudy with periods of rain. South-Southeast 5 to 15 mph. Highs near 47. Sunset: 5:18pm.TUESDAY INTO WEDNESDAY MORNING
TONIGHT: Cloudy skies with areas of fog. A few showers. Winds Southwest 10 to 15 mph. Lows near 43. Sunrise: 6:55am.
WEDNESDAY: Morning showers giving way to partly sunny skies. Highs near 58. Record High is 59 set in 2009.
WEDNESDAY NIGHT: Cloudy skies with rain to wintry mix and then to snow after 2am. Snow could be heavy at times. Lows near 32.Below weather maps from http://www.tropicaltidbits.com/analysis/models/GFS model start time towards 1am-4amRPM Model - start time by 4amGFS Model 7am ThursdayRPM model 8am
THURSDAY: TRACKING COASTAL STORM. Snow, moderate to heavy in the morning tapering off in the afternoon. Get the shovels ready with potential of more than 3 inches. We the right track we could see more than 6 inches. Highs near 34.RPM NOON ThursdayGFS 1pm ThursdaySo how much snow? Below are the snow totals from the different models.GFS 7pm ThursdayNAM modelEURO ModelGFS modelRPM modelNational Weather Service forecastNational Weather Service forecast
So with all that being said, How much snow are we getting rich.. ?
1. Start time 2am to 5am - may start as rain or mix before all snow
2. moderate to heavy snow possible 8am to 1pm
3. Track is important - we are on the northern edge so any movement south or east we will see less snow.
4. As of Tuesday morning - my idea - Northern and Western areas of Nassau county 3 to 5 inches of snow, Suffolk county 4 to 8 inches of snow. Highest amounts look to be in Suffolk county.
5. snow will taper off west to east during the afternoon of Thursday
6. very cold weather Thursday night into Friday - lows teens and 20s highs near 30.
THURSDAY NIGHT: Partly Cloudy. Cold. Lows 15 to 22.
FRIDAY: Mostly sunny and cold with highs around 30. OVERNIGHT: Mostly Cloudy with some snow showers. Lows around 25. Minor snow accumulation possible.
SATURDAY: Morning rain or snow showers possible. Partly Sunny in the afternoon. Highs near 43. OVERNIGHT: Mostly Cloudy, chance of rain or snow showers. Lows near 32.
SUNDAY: Cloudy skies with rain showers. Highs near 44. OVERNIGHT: Mostly Cloudy skies. A few showers. Lows near 35.
MONDAY: Sun and Clouds. Highs near 44. OVERNIGHT: Mostly Clear. Lows near 30.
UPDATE BY METEOROLOGIST MATT HAMMER ON SUNDAY JANUARY 22ND, 2017 AT 5:00PMGood evening! While the southeast US has been dealing with severe weather, including tornadoes, this weekend, we gear up for our nor'easter that arrives Monday.Today we've seen a lot of clouds and we did have some breaks of sunshine too. Temperatures stayed very mild again with highs into the upper 40s and lower 50s! Islip MacArthur Airport hit a high of 54 today. This is actually a NEW RECORD which breaks the previous record of 51 degrees set last in 1986! However, we have much more important things to talk about than a new record high temperature today.As we go into tonight, you'll notice the wind start to pick up.Our HIGH WIND WARNING officially begins 1AM Monday and goes until 1AM Tuesday. We're looking at sustained winds of 30-40 mph with gusts at least 50-60 mph. It is very possible to see some isolated gusts that go higher than this. In fact, take a look below and you can see what the National Weather Service is outputting for the MAXIMUM potential wind gust through the storm. Montauk point with the potential to see a 70+ gust! Whether it's 50-60 mph or a few higher gusts, these winds mean business and will create problems tomorrow.This means we'll likely see at least some power outages...with the best chance for this during the afternoon and evening hours on Monday. We'll be bordering on the "moderate" potential by that point.Take a look at the forecast weather map images below to give you a better idea of what the RAIN situation is looking like for this storm...around 8PM tonight - mainly cloudy skies with a few spotty showers possible...Monday morning around 7AM...expect light rain showers...nothing too crazy with the rain just yet, but by this point the WIND will really be cranking already and we could see some MINOR coastal flooding during the early high tide cycle.By early afternoon, and definitely by 3PM as depicted here, we're looking at moderate to heavy windswept rain and dangerous driving conditions. We have to watch for some ponding on roadways in addition to the strong, gusty winds.Well to our NW, there could be some wet snow mixing in, but this is NOT the case this time for Long Island.Here on LI we are looking at a rain event. With a nor'easter like this during this time of the year, many times we WOULD be talking about a big snowstorm, but not this time. By 6PM across Nassau and Suffolk, we're still dealing with the heavy rain and very strong winds...Showers will linger Monday night and into the day on Tuesday. Throughout Tuesday, we will see gradually improving conditions with some clearing by Tuesday night.Total rainfall amounts through the storm look to be on the order of 1 to 3 inches with some locally higher amounts possible.TO RECAP:We do not want to minimize the coastal flooding concern for tomorrow AT ALL. During Monday's first HIGH TIDE CYCLE, expect minor coastal flooding. You can see some of those high tide times below:For the SECOND round of HIGH TIDES on Monday, that is when we are concerned about moderate to LOCALLY MAJOR coastal flooding. Places like Freeport, Lindenhurst, all of our low lying coastal communities that are flood prone, etc. Tides will be running 3.5 to 4.5 feet above normal! You can see some of those high tide times for round two below:Once we get through the storm, we get the return of sunshine on Wednesday and it looks like drier weather will prevail for the rest of the week. It stays quite mild for Wednesday and Thursday. After that, temperatures drop to near seasonable levels Friday into next weekend.That's all for now. Please tune into Bruce Avery this evening and overnight on News 12 Long Island for updated forecasts. Rich Hoffman will guide you through the weather during the morning rush followed by Bill Korbel in the afternoon and evening.Feel free to reach out to me as well on Facebook, Twitter or Instagram and I'll do my best to respond. Also, tomorrow -- we can certainly use your storm photos and video! PLEASE ONLY TAKE PHOTOS AND VIDEO IF YOU CAN DO SO SAFELY! You can share with us on social media and email us at LIDesk@news12.com. From all of us here at News 12, we hope you stay safe during the storm and we'll do our best to give you the most up-to-date and accurate information possible.Have a great evening!Your Weather Friend,- Matt HammerInstagram: SEARCH "MATTHAMMER619"
UPDATE BY METEOROLOGIST MATT HAMMER AT 8:45AM ON SATURDAY JANUARY 21ST, 2017I hope you are all off to a great start to the weekend! We have quite the weather ride on the way for Monday and not the best of weekends of weather either. So, let's go over it!We started off today with an overcast sky and also some reduced visibility in spots with patchy fog. Areas of fog will be returning tonight.Cloudy skies dominate the day today. At best, we'll see some brightening or a few breaks of blue sky in the overcast conditions through this afternoon. You can see the forecast map below showing the clouds holding through this afternoon...Late tonight, it's still mainly cloudy and it will be dry before midnight.Rain showers arrive Sunday morning...Periods of scattered rain showers Sunday afternoon...By Monday, we'll be dealing with a Nor'Easter. You can clearly see those tighter lines. No, that's not an error - that's a STRONG easterly wind gusting 50 to 60 mph.In fact, we already have a HIGH WIND WATCH posted for late Sunday night through Monday night:We'll first start to notice the wind pick up a bit Sunday afternoon and evening...By Monday morning, as you can see above, we'll have SUSTAINED WINDS 25 to 35 mph with much higher gusts.So our STORM WATCH HEADLINES: Coastal flooding will be a big concern Monday as well.Through Monday evening, we're looking at 1-2" of rain with some additional rain after 7pm Monday too.To recap today - Mainly Cloudy - light winds for now - highs WELL above average in the low 50s!Tonight will be dry to start, but expect a shower late after midnight.Our primary weather concern over the next 7 days is our nasty Nor'Easter for Monday. Power outages will be possible with those strong gusty winds. Also, as can be a big problem here on our island, coastal flooding will remain one of the top impacts of the day. Slow improvements Tuesday, then a really nice day on Wednesday. Temperatures stay above average through the end of the week. After that, it will get colder for the last few days of January and beginning of February...it is winter after all. :)Have a great day!- Matt HammerFacebook: http://www.facebook.com/MattHammer12Twitter: http://www.twitter.com/MattHammer12

UPDATE BY METEOROLOGIST MATT HAMMER AT 8:30AM ON January 8th, 2017
Good morning! We had a partly sunny start to the day today, but even though we are seeing some sun to start, don't let that deceive you! It is downright frigid outside!
Early morning temperatures were in the teens, but as if that's not cold enough...it feels even colder! We still have a windy day today with winds NW 15-25 mph. Early this morning, winds were sustained around 5 to 15 mph with gusts 20 to 25 mph.That wind makes it FEEL LIKE the single digits all day long today...
Let's quickly recap our storm from yesterday - our first significant widespread Long Island storm of the season so far! Let's look at Suffolk first - our early morning forecast numbers yesterday before the first snowflakes flew were 4 to 8" West of Rt. 112 and 6 to 12" East. In the end, we were towards the higher end of the 4 to 8" in Western Suffolk with a few locations overachieving by around an inch or so. East of Rt. 112 - within range - around 10" to 12"
In Nassau, as you can see above, we were forecasting 4" to 8" before the first flakes fell and ended up on the higher end of that, with several locations exceeding by one or two inches.
So, hopefully your cleanup is well underway and I hope you all remained safe in the storm. Back to today...
Take a look at the futurecast images below and we'll notice that we do run the risk for some flurries or a passing steadier snow shower this afternoon. We are not talking about anything that would really accumulate on top of our snow from yesterday. At worst, a dusting or fresh coating will be likely under any steadier snow shower should one hold together well passing over Long Island.
What we're watching today, as you can see above, are snow showers and flurries from the Great Lakes streaming south and east towards Long Island. Use the arrow to the right of each image to advance the graphics...
1 of 4
So, to recap today: (REMINDER: Low 20s feel like single digits with the wind...adding insult to injury)
Out on the water today...
Even though it is frigid outside, it would still take over 30 minutes to get frostbite. That being said, please still dress in multiple layers today and cover as much exposed skin as possible if you're heading outside! As we head into the heart of winter though, take a look at the frostbite potential chart from the National Weather Service below...
Over the next seven days, we have snow melting that will happen easily with warmer temperatures arriving and a few chances for some rain showers...
Have a great day!
Please continue to send in your storm photos and videos to either the News 12 Long Island social media pages or to mine using the following links:
UPDATE BY METEOROLOGIST MATT HAMMER AT 8:00AM on January 7th, 2017
Good morning! I just wanted to post a brief update on the latest forecast for you here this morning with our latest snow totals.A WINTER STORM WARNING is in effect for all of Long Island...
Here's our storm as of 8AM this morning...Any darker blue shadings indicate where more moderate to heavy snow is...
It is definitely plenty cold to support snow! These temperatures will remain fairly steady through the day. With temperatures this cold, we're looking at a drier and more powdery snow.
That's important because the wind will be a factor today and aid in blowing that snow around a bit.
Winds this morning were sustained about 10-20 mph...
Take a look at the futurecast images below and you can see that we will be dealing with steady snow this afternoon and evening...highest amounts will be East...use the arrow to the right of the image to advance the graphic...
1 of 3
Please try not to travel this afternoon and evening unless you absolutely have to. Roads will become dangerous quickly...poor visibility with moderate to heavy snow...
Latest SNOW TOTALS - Please check back with us for any updates...
Over the next 7 days, we will see a mix of clouds and sun tomorrow with a few passing snow showers possible, but nothing too significant...watch for icy and snow covered roads today through tomorrow...
We see much milder weather return by mid-week with a few chances for rain showers...
Please send in your snow photos, videos and latest totals! Remember, if you still have some snow on the ground from Friday, try to clear a path on the grass to start fresh with new measurements from today's storm! You can send any of this to our News 12 Long Island social media pages or by searching "Matt Hammer 12" on Facebook or Twitter...
Have a great day and be safe!

Good Morning - Forecast update by METEOROLOGIST RICH HOFFMAN SUNDAY DECEMBER 11TH 2016 AT 10AM.
A cold start to our morning with temperatures in the 20s. I am tracking a storm that will move through the Great Lakes and Bring a little snow and then rain to Long Island starting this evening into Monday.
So, what can we expect. First, Long Island weather is always different than areas North and West of Long Island when it comes to snow storms. Second, listen to the forecast and know who is forecasting for what areas. Third, Stay tuned to News12 and download the News12 weather app.
Today: Temperatures in the 20s this morning. Clouds will increase through the day and become cloudy this afternoon. Temperatures between 3 and 6pm will range from 30 to 35. Cold enough for some snow and some slick roads. Some light snow and flurries will develop late afternoon, mostly on the light side. Once the sunsets, with the cold roads, even a half inch of snow could create slick roads so be alert driving this evening.
TONIGHT: Cloudy skies with temperatures from 6pm to Midnight in the 32 to 35 degree range. We will have some light snow or flurries. Some minor snow accumulation. Most areas half inch or less, some areas could see around 1 inch. If the Precipitation comes down for a period, some areas could see 1 to 2 inches. As you can see we are not expect a lot of snow, but even minor snow can create issues on the roads. After MIDNIGHT: Temperatures will rise to close to 40 and any snow will change to rain. Any snow accumulation will be washed away.timeline showing snow going to rain and warmer air on the way.
THE BELOW WEATHER MAP IS FOR 1AM MONDAY......You can see the snow changing over to rain at this point. Temperatures are warming to around 40.1am Monday weather map.
MONDAY: Morning rain, heavy at times. Temperatures will be in the 40s. Some puddles and slick roads will create a sloppy morning rush hour. Winds Southwest to West 15 to 25 and gusting to 35 mph. Rain will taper off after 2pm, it will be windy and mild. Highs 45 to 50. Sunset: 4:25pm.

UPDATE BY METEOROLOGIST MATT HAMMER - SUNDAY DECEMBER 4TH, 2016 - 10:30AM
Well, I hope everyone is having a great weekend so far! Today is a really nice day to finish the holiday outdoor decorations, get a Christmas tree or do anything outdoors! It won't be warm, but at least it looks great with plenty of sunshine.
Here's what's going on. We have dry weather in control for today, but take a look below and notice all the green and blue colors to our South and West. That's what we're watching for late tonight and Monday morning.FUTURECAST SLIDESHOW: Use the arrows to the right of the below image to advance to the next graphic...After an afternoon of mainly sunny skies, clouds begin to increase later tonight...The information that is put into these images comes from our computer forecast guidance models...It's not always "what you see is EXACTLY what you get" with these projections. So, focus on the general idea here. Showers arrive after midnight. There's a good chance at a mix of snow and rain showers to start...After a mix of rain and snow showers to start the day, plain rain showers continue from mid-morning until around noon Monday...
1 of 3
Back to today for a moment - our morning lows today were definitely cold - generally upper 20's to lower 30's.
Through this afternoon, we'll be in the lower 40's with a NW breeze at 10-15 mph. The normal high this time of year is 47 degrees. Plenty of sunshine though as I mentioned, so enjoy it! We'll just see some high, thin and wispy cirrus clouds today.Waters look OK for the rest of today...just a bit breezy!
Our weather changes begin tonight with increasing clouds before midnight. Lows should bottom out around the lower 30s.
The below map is from the National Weather Service (NWS) and tells us their thinking on our wet and slightly wintry weather event on the way for late tonight and Monday morning. North and West of Long Island is where the best chance at some light snow accumulation is.
This map below is also from the NWS and shows the likelihood at seeing more than one tenth of an inch of snow. Notice how the chances of this aren't all that great on Long Island. Even if we do get a quick coating in spots, a transition to all plain rain showers all across LI instead of a mix of rain and snow is likely after daybreak. So, this next system is going to be mainly wet instead of mainly white or wintry. That being said, there may be a few slick spots very early tomorrow morning, but nothing much more than that.
Now, that all important Hyper-local 7 Day Forecast!
A bit unsettled at times this week, but the big highlight will be the much colder air that's on the way as we head towards next weekend!
As always, if you have any forecast comments, questions or weather photos - head to my social media pages and I will get back to you as soon as I can.
Have a great day and upcoming week!

Update By Meteorologist Matt Hammer at 9:30AM on November 19th 2016
Good morning! We've been talking about a big change in the weather for awhile now and it is almost here. So, if you're a fan of warmer than average temperatures (I sure am!) then try to get outside today and enjoy one last day of this warm weather. Big changes start tomorrow.
Above you can see a map of what's happening today. As of 9:30AM this morning, skies were mostly sunny all across Long Island. This will change throughout the day. Starting with the eastern half of LI - you can see the grey color offshore. Those are clouds pushing back West towards Long Island. So this afternoon, skies become increasingly cloudy for Eastern then Central Suffolk County. Back to the West, we have a cold front advancing East. Along with it...the chance for some wet weather starting tonight. It also marks the leading edge of our colder air.
Take a look at the Futurecast slideshow below for more on the timing of the wet...and perhaps brief chance of some wintry weather...Unfortunately, there are other changes too and not just with the air temperatures. A big factor tomorrow and really into Tuesday will be the WIND. Take a look at the projected SUSTAINED wind speeds tomorrow and Monday:By tonight, skies are mostly cloudy with scattered showers arriving...Showers continue overnight...Sunday won't be a washout, but there will be the chance for a few showers. During the afternoon and evening, any shower may have a few wet snowflakes mixed in...Chance for a rain shower or couple of snow showers...Dry by Monday afternoon...
1 of 5Sunday morning sustained winds - 20 to 30 mph with higher gustsMonday morning sustained winds - 20 to 30 mph with higher gusts
Gusts over the next two days will likely be between 40 and 50 miles per hour. On Tuesday, it will still be very breezy, but not as windy. So far we've gone over the change in terms of rain and perhaps a snow shower or two, the wind and to top it all off it will feel MUCH colder.
So, let's recap:
Our "jumping off point" today, as I like to call it, varied across Nassau and Suffolk. You can see those morning low temperatures below:Normal Low = 36
Expect a lot of sun to start the day with increasing clouds over the East End this afternoon and all across Long Island we'll see more clouds starting this evening. We could at least tie a record high today set back in 1999!No advisories until 6pm...Small Craft Advisory starts then...have to watch for Gale Force Winds tomorrow and Monday...Scattered showers arrive tonight. Otherwise, mostly cloudy. Lows near 40. Becoming windy.
Over the next 7 days... windy, colder and unsettled tomorrow with a few showers. It will feel more like the 20s and 30s over the next couple of days due to the colder temps in conjunction with strong winds. Highs Monday and Tuesday will be around 44 with mainly dry weather. The wind subsides considerably finally by Wednesday. It does look like we could have some showers to contend with on Thanksgiving, but at least it will be feeling a bit better outside with highs around the low 50s again.
Have a great day! Remember, if you have any weather photos, videos or comments - please reach out to me on social media using the links below...thanks!

Update by Meteorologist Matt Hammer 10:30AM October 22nd 2016
Good morning! Clearly, it is not a great start to our weekend in terms of the weather. It's damp, gloomy, chilly, windy....a day to enjoy inside!
So, there's a few things to discuss about today. The biggest weather story will end up being the wind. Yes, we also have the periods of rain showers to contend with as well. Rain will start to taper off this afternoon, but we cannot rule out showers until later this evening and tonight...
Our HIGH TEMPERATURE for the day actually occurred a little after midnight. By no means will it be feeling like the mid 60s for the rest of today!
In fact, it quickly got much cooler early this morning as a front came through. See below for what temperatures were like around 10AM:
Chilly! What makes matters worse is the wind. Winds will be strongest this afternoon and tonight.
Above, you can see what sustained winds were like around 10AM. Breezy, but not horrible...yet.Wind gusts this morning were generally between 20 and 30 mph.By this afternoon and evening, winds will be sustained 20-30 mph. Gusts by this point can be expected around 40-50 mph.
Below you can see how the radar was looking around 10AM. Note the general idea here. We still have a few rounds of these showers to get through. The occasional downpour cannot be ruled out either. We will begin to dry out throughout the afternoon, but scattered showers will be possible...
FUTURECAST RAIN / CLOUDS / TEMPS:Early this afternoon...showers remain. CHILLY! Temps in 40's and it will feel even chillier when you factor in the wind...This evening, still the chance for a couple of showers, but the rain will be much more scattered by this point...still very chilly too...Overnight...skies clear......and a little something EXTRA if you were wondering or need to know...here's the latest allergy report:We wake up to plenty of sunshine tomorrow morning, but you'll need the heavy fall coat!You do NOT want to find yourself out on the waters today...GALE WARNING!
So, let's recap today's headlines...Try to secure any loose outdoor objects if you have not done so already...we see SOME improvements starting tonight...
Now, the next seven days...SEE BELOW THE IMAGE FOR FULL 7 DAY FORECAST TEXT DETAILS!
Wind Advisory starting at 2pm! Winds will be strongest this afternoon and into this evening. Gusts may approach 50 mph. Chance for scattered downed tree limbs and isolated power outages. Be sure to secure loose outdoor objects. Also, watch out for roads covered with wet leaves. This will make driving a bit more slippery. Cloudy with periods of rain showers today. Highs occurred just after midnight - around 66 at Islip. Temps fall through the day. Afternoon temperatures will be closer to 50 degrees. Chilly!
Wind Advisory. Chance for a leftover shower early, otherwise clearing skies overnight. Lows near 43 degrees. Still Windy. Winds WNW 15-35 mph.
Mainly sunny. Windy and cool. Highs near 60 degrees. Winds WNW 20-35 mph.
During the early morning hours, around 4AM-7AM, there could be a shower. Mostly sunny skies develop for the afternoon. Highs near 62 degrees. Normal high = 60. Breezy. Winds NW 10-20 mph. Record High = 74 (2001). OVERNIGHT: Mostly clear and chilly. Lows around 41 degrees. Some 30's in Pine Barrens. Normal Low = 43. Record Low = 30 (2003).
Mostly sunny and cool with highs near 53 degrees. Normal high = 60. Record High = 76 (2001). OVERNIGHT: Partly cloudy to mostly clear. COLD! Lows around 36 degrees. Low 30's in Pine Barrens. Normal Low = 42. Record Low = 32 (2013).
Mostly sunny and staying cool. Highs near 54 degrees. Normal high = 60. Record High = 73 (1989). OVERNIGHT: Partly cloudy and chilly with lows around 38 to 43 degrees. Normal Low = 42. Record Low = 30 (2006).
Increasing clouds. Highs near 57 degrees. Normal high = 59. Record High = 72 (1989). OVERNIGHT: Mainly cloudy. Lows around 42 degrees. Normal Low = 42. Record Low = 31 (1988).
Cloudy with periods of rain. Highs near 59 degrees. Normal high = 59. Record High = 74 (1989). OVERNIGHT: Showers end. Lows near 45 degrees. Normal Low = 42. Record Low = 32 (2000).

Updated by Meteorologist Matt Hammer 1:00PM October 8th 2016Our cloudy and at times, showery start to the weekend...Good afternoon!While our weather could look a lot better right now, thankfully it is nothing like those living along the Southeast coast of the US have been dealing with thanks to Hurricane Matthew. Matthew officially made a landfall near McClellanville, SC at around 10:45AM. The Carolinas continue to deal with the gusty winds and dangerous flooding rains as we go through today.Below you'll see a snapshot of what Matthew looked like around 12:30PM along with the updated track from the National Hurricane Center from 11AM.The brightest colors = the heaviest of the tropical rains.In terms of our weather across Long Island, see the futurecast images below. Just click the arrow to the right to advance each graphic!Thankfully, Matthew is expected to continue weakening and move offshore through the day tomorrow. You can see the latest track DOES NOT include that "loop" back towards the Bahamas that was originally anticipated. Matthew should be a tropical depression by Monday...Scattered showers this afternoon...Areas of steadier showers tonight...chance for a tropical downpour.Widespread showers early Sunday morning...Starting to dry out Sunday afternoon...
1 of 4We could see around a quarter to one half inches of rain in spots through tomorrow afternoon. NOTE: Rain will hold on longest for the East End and will end from West to East with also some breaks of sun likely from West to East too through tomorrow afternoon.
Quick Check of Today's Allergy Report:
Out on our waters today:As we go through the overnight hours and into our Sunday, the wind will pick up a bit. We could have some gusts to around 25 mph tomorrow. The image below shows expected sustained winds around 10AM Sunday morning...So, tomorrow starts off with rain. Gradually improving weather during the afternoon. Columbus Day Monday looks great with sunshine and cool temps in the low 60's. After that, the rest of the week does not look bad either with partly to mostly sunny skies and highs in the 60's.Have a great day!- Matt HammerFollow on Twitter: www.twitter.com/MattHammer12"Like" on Facebook: www.facebook.com/MattHammer12
Updated by Meteorologist Rich Hoffman 1030am October 4th
Below is the track from the National Hurricane Center
Hurricane Matthew is a Slow moving storm - For the most part moving North between 5 and 10 mph. The storm will start moving to the Northwest over the next 12 hours impacting Bahamas and then near the East Coast. Most of the Computer agree to a Hurricane within 100 miles of the East of Florida towards Friday Morning. The left side of a Hurricane is the weaker side but still can be very dangerous with strong winds, heavy rain, and coastal flooding. Comparing two of the more well know models, the American GFS and the European ECMWF we have difference in track and speed starting late of Friday - See the below maps. The storm could be Post -Tropical as it passes Long island or Strong Tropical storm to low end category one hurricane.NHC forecastYellow line Euro, Red Line GFS - pressure fields
By 2pm on Saturday you see a difference in Location - GFS is faster to the North and on the Coast of North Carolina - If this happens this would move likely be a landfall as a Strong category 1 or 3 Hurricane. ECMEF Euro keeps storm off shore but close enough for major impacts in the Southeast.
You can see on the above map the models are close together Near Northern Florida on Friday - Not making landfall but close enough to produce heavy rain, strong winds and coastal issues.6am Sunday
Big difference in timing and location in the two models - GFS much closer to Long island with greater impacts. EURO much further south at this point with less Li impact.GFS at this point racing past long island.
So if the GFS model happens what to expect - SATURDAY: Partly Sunny to cloudy skies. Breezy. Showers towards evening. Highs 67 to 72. OVERNIGHT: Cloudy. Periods of Moderate to Heavy Rain. 2-4 inches of rain. Windy - gusts 25 to 50 mph. Beach Erosion and Coastal Flooding. Lows near 60. SUNDAY: Cloudy. Periods of Moderate to Heavy Rain. 1-3 inches of rain. Windy - gusts 25 to 50 mph. Beach Erosion and Coastal Flooding Highs - Sunday night gusty winds 20 to 40 mph, showers ending. Lows 47 to 52. COLUMBUS DAY - Mostly Sunny, windy Highs near 63.EURO by Monday 5am
IF THE ECMWF ( EURO MODEL) IS CORRECT - what to expect - SATURDAY: Partly Sunny skies. Breezy. Highs 67 to 72. SATURDAY NIGHT. Cloudy. Breezy. Chance of showers by Sunday morning. SUNDAY: Cloudy. Periods of Moderate to Heavy Rain. 1-3 inches of rain over eastern Long island, Western Long Island 1 inch or less. Windy - gusts 20 to 40 mph. Beach Erosion and Coastal Flooding possible. Highs 65 to 70 - Sunday night gusty winds 20 to 40 mph, showers ending. Lows 47 to 52. COLUMBUS DAY - Mostly Sunny, windy Highs near 63. Euro forecast shows less of an impact as it will be further south and east as it moves passes long island.
Those are the models, - What do I think? As of now - it is still a watch and wait game for Long island - A lot of things can happen from now til Thursday. Prepare for rain and gusty winds late Saturday into Sunday - Think kinda like strong nor'easter. For now - when storm track changes so will the forecast. I will fine tune the forecast through the week, remember this storm could see go straight out to sea and we see little impacts or go to the west a little more and we could see tropical storm force conditions. Continue to stay with News12, online, on TV and the news12 Weather app for updates.
UPDATE BY METEOROLOGIST MATT HAMMER AT 12:00PM SUNDAY OCTOBER 2ND 2016
Good afternoon! The big weather story as we go throughout this week will of course be Hurricane Matthew. Unfortunately, yes, the strongest storm of the year in the Atlantic thus far just so happens to have my name!
Below is the latest track from the National Hurricane Center on Hurricane Matthew. Still a Category 4 storm with winds around 140 mph. It's latest movement as of 11am today was West slowly at 3 mph. It is expected to turn North tonight. This will be a major storm for Haiti, parts of Jamaica and Eastern Cuba. While the hurricane force winds only extend out 35 miles from Matthew's center, parts of Haiti could see up to 40 inches of rain! High rain totals are expected in Jamaica and Cuba as well. Mudslides and flooding will be huge problems in these locations through tomorrow.
As we head towards the middle of the week, Matthew will be centered over the Bahamas. It's at this point (around Wednesday) that we should get a much better handle on the East Coast impacts, if any, from Matthew.
You probably see the below kinds of maps all over the internet. "Spaghetti plots." The general idea with these hurricane forecast models has been to take the storm towards the coast and then out to sea and sparing much of the eastern seaboard from any major impacts. This is not set in stone though. There are some outliers in the computer guidance models that take the storm more along the coast so we still very much need to watch this closely...hopefully the out to sea track verifies!
That's the latest on Hurricane Matthew for now. In terms of weather for Long Island the rest of today - mainly cloudy and cool with highs near 66 degrees. Some brief areas of drizzle cannot be ruled out. There is a small chance for the skies to at least appear a bit brighter later this afternoon for a time, otherwise cloudy.
Areas of fog develop tonight as our unsettled weather pattern continues...
Monday we will see a better chance for a couple of more steady scattered showers. Otherwise, mostly cloudy. Tuesday will start mainly cloudy with breaks of sunshine. A mix of sun and clouds Wednesday and Thursday. Mostly cloudy Friday. Then, if, and that's a BIG IF, we see any direct impacts from Hurricane Matthew, the time period for that looks to be next weekend. Even if the storm does not take a track too close to Long Island, we will see some increased surf later in the week.
Follow me on Facebook and Twitter for additional updates. Rich Hoffman and Bill Korbel will have new updates on News 12 Long Island tomorrow.
Have a great day!

Update by meteorologist RIch Hoffman 8pm Thursday September 29th
HURRICANE MATTHEW GRADUALLY BECOMING BETTER ORGANIZED...
...HEADING FOR THE CENTRAL CARIBBEAN SEA...
SUMMARY OF 800 PM AST...0000 UTC..
ABOUT 150 MI...240 KM NNE OF CURACAO
MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H
PRESENT MOVEMENT...W OR 270 DEGREES AT 15 MPH...24 KM/H
MINIMUM CENTRAL PRESSURE...987 MB...29.15 INCHES5 day track from NHC
Matthew will be a slow mover and make a right turn over the weekend and then head north to close to the North Carolina Coast. The Overall weather pattern and the upper level weather features will help steer Matthew. As of right now it looks like Matthew will stay south and east of Long Island. It will not be until late Monday into early Tuesday morning that we will have a much better handle on the track of the storm. For now we are in a Watch and wait to see how the atmosphere plays out.The below map is the GFS model and shows Matthew at 2pm on Thursday as a strong Category One HurricaneGFS model
Here is the GFS model for Friday 2pm - notice how the storm curves south east away from Long Island. If this patterns holds we may see some beach erosion and coastal flooding. But no major impacts. We would see some rain showers and gusty winds 30 to 40 mph. Again timing for Long Island of potential impacts would be from October 6th to 8th.GFS model for 2pm Friday oct 7th
UPDATE BY METEOROLOGIST MATT HAMMER AT 9:30AM SEPTEMBER 17TH 2016
Good morning and welcome to the final "official" weekend of Summer 2016. We are starting off the weekend with some really nice weather. We are generally seeing mostly sunny skies to start with fair-weather cumulus and some high, thin clouds filtering in at times. It was a rather chilly start to this morning though across parts of Long Island. Take a look at our morning minimum temperatures below!A 40 degree start in Westhampton!
Today is easily going to be the better half of the weekend.
In terms of the tropics...the closest system to us right now is what's left of Julia. This system will actually help enhance some of the rain we'll get later Sunday into Monday. What I'm showing you below is the projected track of Tropical Storm Karl. Hopefully the storm curls back out to sea by the end of next week, but this is something we will be watching closely.
Today will continue to be a great beach and boating day. Even though it won't be the hottest of days, it will still be nice enough to head to the water. Cooper's Beach in Southampton was looking a bit lonely this morning, but there were a few people enjoying sunrise at the beach.
Here's the deal for Sunday. During the day it won't be a washout, but we'll have the threat for some on and off showers. The best chance for Long Island to see heavier, steadier showers and a few thunderstorms will be Sunday night into Monday. Here's the futurecast image for Monday morning showing the potential for lingering steady rain. Parts of LI could get around two inches of rain under the heaviest bands.
Whether you're a fan of the hot summer weather or the cooling trend we see in fall, the equinox is next Thursday at 10:21AM EST.
So, let's recap the next few days. Today is great and the better half of the weekend. All of your outdoor plans will be just fine today...and if you don't have any outdoor plans - try to make some!
Tomorrow is unsettled, the worst being tomorrow night into Monday. After that, gorgeous weather Tuesday with highs about ten degrees above normal. Slightly cooler air returns for the rest of the week, but still above average as we begin the new season of Fall on Thursday.
Have a great day!
Remember to send me any of your weather photos, videos or comments on Facebook and Twitter - thanks!

Tracking Hermine...Update from News 12 Meteorologist Matt Hammer at 4:15PM September 3, 2016Good afternoon!Here's a quick update on what's going on...Tropical Storm Warnings posted for Long Island and the immediate surrounding area...You've noticed the cloud cover, the cooler temps and a bit of a breeze developing today. Overall, not a horrible day, but of course it could be a lot better. All things considered, today is/was the day to do any outdoor activities in addition to securing loose outdoor objects with the weather expected to take a big turn for the worse throughout Sunday and beyond...This is a nice graphic from the National Weather Service highlighting the primary hazards from Hermine locally...Latest HERMINE track as of 2pm Saturday afternoon...little change...You may be hearing the term "post-tropical Hermine" - please don't let this classification fool you! It does not mean that the forecast changes or the storm is weaker. In fact, the storm will strengthen over the warm Atlantic waters and should regain full tropical characteristics over the next 24 to 48 hours...potentially back to full hurricane strength...Please also take a look at this info graphic from the National Hurricane Center...We've been hammering home (no pun intended) the fact that COASTAL FLOODING is going to be the biggest impact from HERMINE here on Long Island. That has not changed.In order of most problematic to least problematic, here's what we're still looking at:1. COASTAL FLOODING / STORM SURGE / BEACH EROSION (WORST Sunday evening through at least Tuesday)Starting Sunday morning we will likely see some minor coastal flooding issues begin to materialize. MODERATE TO MAJOR coastal flooding (Perhaps similar to Irene...) will be likely after that and linger through at least Tuesday. Storm surge should average THREE TO FIVE feet with that five or even six foot surge possible for the western LI Sound on the north shore...very dangerous! In addition, we cannot forget the near new moon phase and tides running two to five feet above normal. You can always see the current day's high tide cycles on News12.com and I will be airing them on News 12 Long Island again tomorrow morning/afternoon.2. WINDSA Tropical Storm Warning (which we have) is put out when tropical storm wind conditions are expected within 36 hours. This equals wind speeds greater than 39 mph and less than 74 mph. Most of our wind GUSTS will be in this category, but we are expecting SUSTAINED WINDS of 25-40 mph...with gusts generally between 40 and 60 mph. This can still cause at least scattered power outages. Strongest winds Sunday evening through perhaps at least the first half of Tuesday. This is dependent on the exact track of HERMINE.3. RAINThe rain impacts with this storm as it currently looks for Long Island is minimal. Generally an inch or two should still do it and most of that would be in the Monday time frame. We do have to watch to see how close exactly the storm gets because it could be a matter of only a few miles with these outer rain bands and if they come close enough parts of LI could see some heavier rain.So, part of this is a "wait and see" unfortunately with how bad exactly the wind and any rain will be, but that coastal flooding problem and erosion will be bad no matter what at this point.
A quick look at the next seven days for you, since we've been focusing on the next couple of days on-air for good reason...we could see lingering coastal flood concerns beyond Tuesday...something we just have to watch for right now...Towards the end of the week, while some of you may be back to school, summer will be back!Please stay safe, stay tuned in to News 12 Long Island or right here on News12.com and we'll keep you covered on the latest throughout the duration of HERMINE's impacts in Nassau and Suffolk.If you have any storm photos or video (safety first!) or questions about the storm and what's to come, please feel free to reach out to me on social media and I will do my best to respond! When it comes to crunch time, this will become more difficult so always check the on-air forecasts and the web site first and foremost.Be safe and try to have a nice weekend!- Matt HammerFacebook: www.facebook.com/MattHammer12Twitter: www.twitter.com/MattHammer12

RECORD HEAT TO END THE WEEK!
It was another hot and humid day across Long Island today. In fact, we broke the previous record high for the day at Islip MacArthur Airport topping out around 92 degrees! The previous record was 90 (2009). Above you can see the rest of today's almanac including our current sunrise and sunset times...
Dew points late this afternoon and into early this evening were still in the upper 60s and low 70s. So, the humidity is definitely still there, but it will be lowering tonight!
Take a look below at our weather headlines:
FUTURECAST IMAGES FOR SATURDAY AND SUNDAY AFTERNOONS:
It really is going to be a nice weekend. In part because we'll have that lower humidity around, especially Saturday, with plenty of sunshine. Hopefully you can spend some time outdoors this weekend. The UV INDEX will remain HIGH so you'll definitely want to use the sunscreen with sun burn times remaining less than a half hour.Nice, clear weather for Saturday!The mostly sunny skies continue for Sunday!
1 of 2
A LOOK AT THE TROPICS: Gaston is still expected to intensify into a hurricane this weekend, but as of 5PM Friday evening Gaston remains a tropical storm with winds around 65 mph. The current projected track takes the storm way out to sea during next week. We do have to watch "Invest 99L" for development over the next several days.
So for tonight, lowering humidity will be the highlight with mainly clear skies...
If you want to do some boating on Saturday - looking good!Island-wide we will have a really nice start to the weekend with sunshine and warm to hot temperatures, but much more tolerable humidity.
The highlights over the next seven days...
We keep the hot temperatures around through the middle of next week. Overall dry conditions. Small chance for a late storm on Monday. The best chance for wet weather will come on Wednesday - a few scattered afternoon showers and storms. Temperatures look to drop off slightly towards the end of next week with highs only in the upper 70's by next Friday...
Have a great night!

Update by Meteorologist Rich Hoffman 11am August 9th 2016Are you ready for the spectacular meteor show - Perseid Meteor Shower. The meteors are the debris trail of the comet Swift-Tuttle. Peak will be August 11th into the 14th, Highest numbers will be the morning of the 12th.
12:53 a.m. EDT, give your eyes 30 to 45 minutes to adjust to the darkness.
So how do you view the meteors?
Look East-Northeast after Midnight - Best times 1am to 4am.
Stay away from Lights - Light Pollution stops most Long Islanders from seeing the beautiful night sky.
Check the weather forecast.
The forecast does call for chance of showers and storms at night - I think we could have breaks in the clouds.

Sunrise 5:21am Sunset 8:27pm - more than 15 hours of daylight
Normal High is 78
Normal Low is 62
Record High is 93 set in 1995
Record Low is 50 set in 2005On June 20th at 6:34pm Eastern Daylight Time, the Sun's direct rays will hit the Tropic of Cancer and we will have more than 15 hours of Daylight - This is also the northmost point that the sun's direct rays will hit. On June 21st the Sun's Direct Rays will start moving south once again back to the Equator for fall. This is why days start getting shorter after the Summer Solstice. If you notice water temperatures take a little more time to warm up. Our warmest water temperatures typical happen in September - Yes water temperatures are warmer in September and October than they are in May and June. This is also why we have a better chance of a tropical system impacting Long Island in late summer and fall compared to early on in the Tropical Season which is from June 1st to November 30th. Remember Sanday was October 22nd to October 30th 2012.June 1st is also the start of Tropical/Hurricane Season. ( June 1st to November 30th)
Generic term for tropical depressions, tropical storms, and hurricanes.You tube video on Hurricanes -
A tropical cyclone in which the maximum sustained surface wind speed is at least 74 mph.
A typhoon is the same thing, just what it’s called in the western Pacific. The U.S. Joint Typhoon Warning Center uses the term super typhoon to apply to typhoons with sustained winds of at least 150 mph.
TROPICAL STORM (T.S.)
A tropical cyclone in which the maximum sustained surface wind speed ranges from 39 to 73 mph. Though less intense wind-wise than hurricanes, tropical storms and tropical depressions can produce destructive and deadly flooding from heavy rainfall.HURRICANE FORECAST FROM NOAA FOR 2016Official Hurricane Forecast - http://www.nhc.noaa.gov/Local National Weather Service Tropcial Page - http://www.weather.gov/okx/tropicalRemember it only takes one storm for it to be a bad season - We have to take it one week at a time, again typically we don't see tropical activity around Long Island until late August into September.The last Hurricane to cross Long Island was Gloria in 1985.Read more on Gloria - http://www.hurricanes-blizzards-noreasters.com/HURRICANE-GLORIA.html
UPDATE BY METEOROLOGIST MATT HAMMER - SUNDAY MAY 29TH 2016 AT 9:00AMGood morning! I hope everyone is having a good weekend so far. If you were hoping to spend Memorial Day outdoors tomorrow, you will have to deal with a good soaking rain unfortunately. Hopefully you can get outside today and enjoy one more day of nice weather.We have sunshine filtered at times by some high, thin clouds. The shot above of some of our hyper-local weather cameras was taken this morning.We are also tracking what's left of Bonnie. At the time of writing this post Bonnie is a Tropical Depression. While we were not expeecting a direct hit from Bonnie, we will have rain influenced by moisture from Bonnie for Memorial Day tomorrow. More on that a bit down the page...Here's a snapshot of what we're seeing across Long Island for today:It will be another great beach and boat day. Just apply the sunscreen early and often because the UV INDEX is VERY HIGH at a 9 again today!Here's a look at conditions today on the water...no advisories and if you will be down at the beaches, just keep in mind there is a moderate rip current risk today - always make sure you swim where there's a lifeguard!Here's a snapshot of what we can expect tonight...rain develops around midnight...Just to give you an idea of the timeline of the rain for Memorial Day, the next several graphics are from our futurecast computer model. Notice the bright colors - that indicates those tropical downpours from moisture from Bonnie streaming North across Long Island. While the rain may be associated with that storm to our South, we do not have to worry about wind tomorrow.After we get through the rain tomorrow, which looks like it will linger at least as some scattered showers into tomorrow evening...the weather for the middle part of the week looks OK. There could be a shower early Tuesday otherwise a mix of clouds and some sunshine with highs near 77. Sun and clouds for Wednesday - 75. Mostly cloudy on Thursday with a small chance for a shower. Towards next weekend, we could have a few scattered showers and storms.Have a great day and enjoy the sun and dry weather while you still can!- Matt Hammer
UPDATE BY METEOROLOGIST MATT HAMMER - SATURDAY MAY 28TH 2016 AT 11:00AM
Our Memorial Day weekend is off to a great start weather-wise! Take a look at some earlier shots from some of our hyper-local weather cameras - plenty of blue sky!
If you're one of MANY on Long Island spending a good deal of time outdoors today then the above graphic is just for you. Be sure to apply the sunscreen often today or you'll likely be hurting tomorrow!
If you'll be near NYC or the five boroughs today, there is an Air Quality Alert in effect. This means that the very young, elderly and those of you with respiratory issues should limit strenuous outdoor activities today and everyone should stay hydrated.
Allergy sufferers like myself - sorry, but the pollen levels remain high today and by this afternoon that "feels like" temperature will range from the upper 70's (South Shore and East End) to the mid to upper 80's (North Shore).
So, island-wide - a nice summer-like day today with highs again well above normal. Dry with a mix of sun and some clouds. Any pop-up shower activity should stay North and West of Long island.Plan on taking the boat out today? The Ocean and Sound are looking good!
Expect dry weather to continue tonight with lows very mild - around 64 degrees. Normal low is 54.
Unfortunately, Memorial Day is not looking great...you can see the futurecast image below showing rain and some downpours...
So today and tomorrow are mostly great. Rain develops tomorrow night and will be heavy at times with the chance for a couple of thunderstorms Monday morning into early Monday afternoon. The rain may start to taper off to salvage some barbeques by evening, but keep checking back with us for any timing changes to this...
Have a great weekend!

I hope everyone is enjoying their weekend. We have another really nice weather day today across Long Island. Plenty of sunshine as you can see from some early morning shots in Woodbury, Riverhead and Long Beach - just use the arrows to advance any of the below slideshows!Woodbury around 8AMRiverhead around 8AMLong Beach around 8AM

So here's what's happening across the country. We have high pressure, which drives our nice weather, in control really across the eastern half of the country right now. That is not good news for our friends out to the west...
Notice all of the snow and rain out west - all of which has been slow moving due to our high pressure that continues to provide Long Island with sunshine...
Notice to any boaters today - there is a Small Craft Advisory again for the Ocean only, where waves will be 5-8 feet.
Take a look at the forecast graphics below to see what's ahead for the next day or two:Through this evening we will continue to see sunshine and clear skies...More of the same can be expected for the start of Monday...towards later Monday evening we'll start to notice more clouds move on in...Towards early Tuesday morning there is a slight chance for a passing shower or two, mainly towards the east end of Long Island...otherwise just a mainly cloudy start to Tuesday...
1 of 3
So, let's recap the rest of today. Sunshine with highs mainly in the mid 60's. It will be cooler by the immediate shoreline and the east end, but still quite nice there too!
You will need the sweatshirt or light jacket tonight most likely with lows around the lower 40's. The Pine Barrens and places near Westhampton can expect some chillier lows in the mid 30's!
On Monday we get a bit more of a Westerly wind which will allow temperatures to get into the low 70's - a little cooler south and east...
There may be a spot shower early Tuesday otherwise a mix of sun and clouds.
The coolest day of the week will be Wednesday - 58.
After that, Thursday looks great and we see the chance for some steadier showers later Friday into Saturday.
Have a great day!

Have you been outside yet today?! It was another chilly start to the day - in fact COLD in spots! Take a look at this morning's low temperatures below...That being said, it was another gorgeous sunny start to the day too with temperatures getting nice and comfortable again this afternoon. Sunny skies prevail all across the northeast right now!
We will see some high, thin clouds at times, but that's it for today. It will also be a bit cooler right at the shorelines. Use the arrow to the right of the below graphic to see what's in store for tonight...
1 of 2
Over the next 7 days, things keep getting better before "worse." It will be warmer tomorrow and there will be less of a breeze so it will feel even that much better outside.
Monday will be the warmest day of the upcoming week with highs around 71. Clouds increase later on Monday and there will be the threat of a few early showers to start Tuesday. Outside of that, not too much in terms of any wet weather to speak of.
Enjoy this nice spring stretch - finally!

I'll say it again...HOPEFULLY this is the last time we have to talk about snow around here until next winter!
Let's take a look at your weather headlines for the rest of this weekend...We could see a quick coating to AT MOST one inch of slushy snow on colder surfaces through this evening really only if any heavier bands develop.Our high temperature today around 46 degrees actually occurred late this morning.FREEZE WARNING late tonight through the start of Sunday.It will actually FEEL like 15 to 25 degrees overnight tonight...
Heading to Citi Field? Here's your NY METS game forecast!Possible leftover rain or snow shower to start...then mainly cloudy and cold - BUNDLE UP!
There is finally some seasonable spring weather on the way...
Sunday will still be chilly, but after that - some rain moves in later Monday and Tuesday...
Notice the milder temperatures though for all of next week!
Have a great day!

I hope you are having a great start to your weekend, but there is a lot of weather to talk about!It starts with what will continue to be a dreary and damp day for the rest of today, although rain will become a bit more scattered this afternoon under mainly cloudy skies. Highs around 55 degrees. By tonight, we start to see the winds become strong and temperatures fall back into the 30's...A HIGH WIND WARNING goes into effect at midnight...gusts through Sunday morning will range from around 40-60 mph. This will result in some tree limbs and power lines coming down and we'll see the risk for power outages. Wind will diminish Sunday afternoon and evening.
If you're like me, you'll hate that we even have to mention this, but we do...
There will be a period of snow early Sunday morning. We are not expecting much accumulation, but there could be a coating to a half inch or so from around 5AM to 9AM in addition to those potentially damaging winds. Just use caution traveling tonight and tomorrow morning.
Once we get through the wild weather tonight and tomorrow morning, there will be a system that we are watching for Monday likely to bring us rain and snow showers once again. Stay with us for the latest on that wintry mix potential...
Then, it turns dry but colder for Tuesday - a bit milder towards the end of next week, but it will come with the threat of rain again...
THAT'S SPRING FOR YOU!
Have a great day...

Update 1PM March 20th by Meteorologist Matt HammerWinter Weather Advisory - West of William Floyd Parkway starting at 6pm | Winter Storm Warning East of William Floyd Parkway starting at 6pm
Well, "Happy Spring!" ...
We're tracking what will hopefully be our last winter storm of the 2015-2016 winter season.Snow will likely begin as a mix of rain and snow late this afternoon and into this evening before changing to all light to moderate snow overnight.
We are looking at the biggest impacts of this being any overnight travel and your Monday morning rush. Please budget a little extra travel time tomorrow morning. Snow will be ending from West to East from 7-10 am. Take a look at the futurcast images below for more details. Just click the right arrow to advance the graphics...Final Totals: The basic idea here has remained consistent. Less snow to the west, more to the east. 2-5" in areas under the "advisory" (West of the William Floyd Parkway) and more snow around 4-7" East of that under the Winter Storm Warning...I think this futurecast image from one of our computer models is a bit too slow with the start time of our wintry weather. Look for some light mix or snow around this time this evening, even an hour or so beforehand.Overnight, it's all snow any leftover mix quickly changes over. Notice the sharp cutoff just to our north and west...Snow looks to be heaviest during the overnight towards the East End, where that Winter Storm Warning will be in effect overnight.Early Monday morning (around 3-7am) we will still have snow coming down with low visibility due to wind gusts 20-30 mph. The Monday morning rush does not look great...Snow quickly exits Monday morning from 7am to 10am from West to East.Sunshine breaks through late Monday morning into Monday afternoon and we will see our snow begin to melt quickly with temperatures climbing into the 40's.
1 of 5
Remember, we've had snow in Spring before - including this time last year! Four to seven inches fell across parts of Long Island during the official start of Spring in 2015.
Snow starts to melt Monday afternoon. Then, notice the warming trend throughout the week. There could be a few spot showers along the way, but that's about it. Next weekend, I know it's early, but right now it looks great with highs around 50 degrees and lots of sunshine.
Have a great rest of your weekend and be safe if you have to travel in the snow later on and early tomorrow morning!

Update 11am March 18th By METEOROLOGIST RICH HOFFMAN
Say the word Snow and everyone gets into a Frenzy - There is a difference between snow and SNOW. We can have Flurries, Snow Showers, Light Snow, Moderate Snow, Heavy Snow and the Big Ole' Blizzard.
It seems more and more people dislike Snow - Now it's about 80% against 20% for.
So what will happen the next few days.
1. A cold front this evening will bring colder weather starting tonight into the weekend.
2. Storm developing in the Tennessee Valley will Track Northeast and South of Long Island.
3. Spring Starts 12:30am Sunday March 20th when the Sun's direct rays hit the Equator.
4. Rain and Snow develop between 8am and noon on Sunday and ends Monday morning
5. Precipitation Ends Early Monday and then late day sun with highs in the 40s.
6. 50s and 60s end of next week.FRIDAY AFTERNOON: Sun and Clouds. Chance of a shower between 3 and 6pm. Windy. Winds West-Northwest 10 to 20 mph. Highs near 55. Sunset: 7:03pm.Friday to Saturday Forecast
FRIDAY NIGHT: Mostly Clear, a little breezy early. Cold. Winds North-Northwest 5 to 10 mph. Lows near 30, some 20s around the Pine barrens.
SATURDAY: Mostly Sunny with some late day clouds. A little chilly. Highs 40 to 45. OVERNIGHT: Increasing Clouds with chance of snow towards morning. Lows 25 to 30.
SUNDAY: SPRING STARTS 12:30am. PALM SUNDAY. TRACKING COASTAL STORM - Timing, Track and Strength still in question. Cloudy and Cold. Periods of Rain and Snow. Winds North-Northwest 15 to 25 gusts to 35 mph. Wind Chills in the 20s. Highs 35 to 38. Snow during the day this time of year is hard to accumulate on roads - unless it comes down heavy.
Here is a look at the Storm Track -8am saturday8pm Saturday8am Sunday
Below are the SNOW TOTALS from different weather computer Models from 0z model data, 12 z data comes out during the day, 0z is the overnight model runs. From 12z Thursday to the 0z models Friday the track was to the east more. I will track to see if there is a difference from 0z run to the next 12z run. I WOULD PREPARE FOR 3 INCHES TO 5 INCHES, and if a east storm track happens snow totals will go down.. Forecast will change a few more times before Sunday. When snow falls during the daylight hours during the spring it melts when it hits the pavement and snow accumulates on colder surfaces like grassy areas. This time of year the sun is high enough in the sky that even if its cloudy and snowy the sun's energy can melt the flakes as they fall. Hence why it's very difficult to get a major snow storm after March 17th.EURO seems to have the highest amounts as of now and the last 24 hours storm track moved to east and totals went DOWNGFS has the storm, weaker and a bit east hence the lower amounts.NAM HAS A MIXTURE OF RAIN WITH SNOW and keeps the storm more to the southRPM MODEL AS RAIN TO SNOW with more snow north and west of Long Island.
SUNDAY NIGHT: : Wintry Mix and Snow. Be prepared for several inches of snow. Lows 30 to 32.
MONDAY: Morning Clouds and Snow Showers. Icy roads possible for morning rush hour. Windy. Partly Sunny in afternoon. Northwest winds 15 to 25 mph. Wind Chills in the 20s.Be Prepared for a couple of inches of snow. Highs near 44.
MONDAY NIGHT: Partly Cloudy. Cold. Lows 27 to 32.
TUESDAY: Sun and Clouds and Breezy. Highs 42 to 47. OVERNIGHT: Mostly Cloudy. Lows 30 to 35.
WEDNESDAY: Partly Sunny. Warmer. Highs in the low 50s. OVERNIGHT: Partly Cloudy. Lows 40 to 45.
THURSDAY: Sun and Clouds. Mild. Highs 53 to 58. OVERNIGHT: Mostly Cloudy. Lows in the 40s.
UPDATE MARCH 5th AT 8:30AM - BY METEOROLOGIST MATT HAMMERSaturday morning sunshine in Riverhead.
We started off our weekend with a gorgeous sunrise this morning. Mostly sunny skies started the day all across Long Island. As we go through today, we will notice clouds increase this afternoon. It will stay dry. You can see in the picture below that we have a batch of snow showers and flurries to the west. Those will be weakening before reaching us. At worst, we're looking at a few morning flurries or a snow shower early tomorrow.
Today will be nice and dry. Normal high for this time of the year is 45. So, we will be a little below average today with those increasing clouds. Tonight will become mostly cloudy and there could be a passing flurry very late, otherwise dry.
Take a look at the futurecast below to see how the rest of our weekend pans out. Just click the arrow to the right to advance the images:Afternoon clouds today after morning sunshine...mid 30's around 5pm after highs near 40 degrees...A late flurry possible overnight, otherwise the best chance for any snow looks to be early tomorrow morning in just the form of a few passing snow showers at worst. Temperatures at the surface by this point will be above freezing...After an early flurry, clouds clear for sunshine on Sunday. Highs in the low 40's...
1 of 3
We have a MAJOR warm-up on the way for the upcoming week. We'll have late April to early May weather for the middle of the week! Take a look at projected highs through Thursday below...that'll feel nice - who agrees?! The record high for Wednesday is 64 (2000). We have a good shot at breaking that!
Other than the big warm-up on the way, dry Monday through Wednesday with partly to mostly sunny skies. Showers arrive for the end of the week as temperatures cool back into the mid-40's by the start of next weekend.
Have a great day!

UPDATE FEBRUARY 29TH AT 9:00PM - BY METEOROLOGIST MATT HAMMER
As we round out meteorological winter and head into meteorological spring, we had quite the mild day today after a line of rain showers moved through. We got back into that sunshine and once we did, temperatures rose fast across Long Island. Take a look at today's high temperatures on the map below:We actually set a new record leap day high at Islip MacArthur Airport just before 5pm! We hit 58 degrees then which broke the previous record for Feb. 29th previously set in 2004. If you were in Nassau County, you had temperatures in the low 60's today. Our normal, average high this time of the year is 43 degrees. However, some cooler air is on the way.
Satellite and radar will look like the above image throughout the overnight hours - nice and dry.
Heading to the bus stop in the morning? Check your school day forecast below:
We do have a dry day on the way for Tuesday, but there is some rain that will be back in the picture by Tuesday night. Click through the futurecast images below to see around when the rain arrives...Dry Tuesday afternoon with sunshine and a few clouds...Becoming cloudy with scattered showers arriving Tuesday night...Periods of rain Wednesday morning with some embedded heavier downpours...Rain and clouds exit during Wednesday afternoon...
1 of 4
BOATERS: Here's a look at what conditions will be like on the ocean and sound tomorrow:
So, let's recap what's on the way. Overnight - partly cloudy and colder with lows in the 30's.
Tuesday starts dry, then cloudy with showers later Tuesday night.
Periods of rain, especially through Wednesday morning.
Over the next seven days, after those showers Wednesday morning, it turns colder for Thursday, but it will be dry. We are tracking a coastal storm for Friday. The computer models MAINLY keep this system offshore for right now, but if there is an adjustment to this then that could mean we would see more snow for Long Island. It's something we'll track closely this week.
Dry after that for the start of the weekend and then we could see a few snow showers by Sunday.
Have a great night!
