HAVE A GREAT DAY METEOROLOGIST RICH HOFFMAN -
UPDATE MARCH 5th AT 8:30AM - BY METEOROLOGIST MATT HAMMER
Saturday 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 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 saturday
8pm Saturday
8am 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 DOWN
GFS 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 south
RPM 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 BY METEOROLOGIST MATT HAMMER - MONDAY MARCH 28th 2016 at 4:15PM
Good evening! After our rain today, we have drier weather on the way, but there will be more wind around tonight and tomorrow. We have a WIND ADVISORY in effect...see the below graphic and slideshow for more information on that.
Wind Advisory posted from this evening until 6pm tomorrow (Tuesday)...Gusts to at least near 40mph...
Sustained winds tonight will range from 20 to 30 mph with higher gusts...1 of 2
Our high temperatures today ranged from the upper 40's (east) to the lower 50's...
Normal High: 51 DegreesIn order to visually show you what's on the way, take a look at the futurecast slideshow below and the captions beneath each graphic. Just click the arrow to the right to advance each graphic...
It's always a good idea to look at the overall recent and projected weather trends. I find it particularly interesting to look over these temperature trend graphics. Notice how recently we have been close to normal average high temperatures. There are two graphics to look at in the below slideshow...
FUTURECAST: TONIGHT - Partly Cloudy to mostly clear... temps around the upper 40's to near 50 this evening...
FUTURECAST: EARLY TUE AM - A bit chilly, but not too bad with temps around 5AM close to 40 degrees...dry with partly cloudy skies...
FUTURECAST: TUE PM - Mostly Sunny with highs once again close to "normal" - near 52, upper 40's can be expected again towards the East End of Long Island...
FUTURECAST: TUE NIGHT to WED AM - It will be dry, but colder by Tuesday night and early Wednesday morning with lows back in the lower to middle 30's...1 of 4
The best days of this week are going to be tomorrow and Wednesday...after that we do see the chance for some rain...
For the most part, we have been close to seasonable levels in terms of temperatures over the last 7 days. The "straight line" in the middle of the temperatures on the above graphic represents the "normal high" for this time of the year...
Here's a look at the forecasted temperatures for the next five days...We see a brief warm-up and actually after Saturday we're looking at colder temperatures (40s) to start the first full week of April...1 of 2
A pair of dry days for Tuesday and Wednesday, then we see an increasing chance for rain Thursday into Friday...
Notice the brief warm-up Thursday and Friday, followed by the colder temperatures Sunday and Monday...

UPDATE BY METEOROLOGIST MATT HAMMER - SATURDAY APRIL 9TH 2016 AT 1:00PM
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!

Update by Meteorologist Rich Hoffman 9am June 1st 2016.ÂJUNE 1ST - The start of Meteorological Summer - (June - July and August) The 3 warmest months of the year.Summer Solstice - (Astronomical Summer) is Monday, June 20, 2016 at 6:34 PM EDT
When the sun's direct rays hit the tropic of Cancer (23 1/2 degree north)
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 2005ÂOn 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.

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.

WEATHER MAP - MONDAY SEPTEMBER 5TH Â -
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 5
Sunday morning sustained winds - 20 to 30 mph with higher gusts
Monday 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 - 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 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!

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...
TONIGHT:
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!

UPDATE BY METEOROLOGIST MATT HAMMER AT 8:45AM ON SATURDAY JANUARY 21ST, 2017ÂI 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!ÂÂ
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.ÂÂ
ÂCloudy 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...Â
ÂLate tonight, it's still mainly cloudy and it will be dry before midnight.Â
ÂRain showers arrive Sunday morning...
ÂPeriods of scattered rain showers Sunday afternoon...
ÂBy 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.
ÂIn fact, we already have a HIGH WIND WATCH posted for late Sunday night through Monday night:Â
ÂWe'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.ÂÂSo our STORM WATCH HEADLINES: Coastal flooding will be a big concern Monday as well.
ÂThrough Monday evening, we're looking at 1-2" of rain with some additional rain after 7pm Monday too.
ÂTo recap today - Mainly Cloudy - light winds for now - highs WELL above average in the low 50s!
ÂTonight will be dry to start, but expect a shower late after midnight.
ÂOur 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. :)ÂÂHave a great day!Â- Matt HammerFacebook: http://www.facebook.com/MattHammer12Twitter: http://www.twitter.com/MattHammer12Â

UPDATE BY METEOROLOGIST MATT HAMMER ON SUNDAY JANUARY 22ND, 2017 AT 5:00PMÂÂGood 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.ÂToday 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.ÂAs 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.
ÂTake 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...
ÂMonday 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.
ÂBy 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.
ÂWell to our NW, there could be some wet snow mixing in, but this is NOT the case this time for Long Island.
ÂHere 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...
ÂShowers 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.
ÂTO 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.ÂThat'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.ÂFeel 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.ÂHave a great evening!ÂYour Weather Friend,- Matt HammerÂInstagram: SEARCH "MATTHAMMER619"Â

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-4am
RPM Model - start time by 4am
GFS Model 7am Thursday
RPM model 8amTHURSDAY: 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 Thursday
GFS 1pm ThursdaySo how much snow? Below are the snow totals from the different models.
GFS 7pm Thursday
NAM model
EURO Model
GFS model
RPM model
National Weather Service forecast
National 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 Thursday6. 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 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

UPDATE BY METEOROLOGIST MATT HAMMER AT 10:30AM ON FEBRUARY 18TH, 2017
Happy 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 AT 2:00PM ON MARCH 9TH, 2017
Good 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 6
So, 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 Caption
Overnight...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 -
