December 1st-2nd Winter Storm Observations

Final call snow map - includes today's snowfall as well



Look for light to moderate snow/sleet/freezing rain to begin between 11am-1pm today from southwest to northeast. From CNJ to NE NJ and NYC, expect the wintry precip to changeover to rain around 3-4pm, maybe a little earlier. Areas in a mix (N&W of NYC) may see minor snow accumulations, but for the most part, will be in a mix with dangerous icing developing this evening. Please avoid roads if possible.

The summary for today is little to no snow accumulations and if they do happen it will be N&W of NYC, maybe 1-3".

The overnight hours things get interesting. The secondary low is poised to develop off the coast of NJ but staying very close to the coast, well inside the 40/70 BM. CNJ, NYC and LI could be in a dry slot overnight into the morning hours with either light rain or no precip falling. N&W will continue seeing a mix - even into the overnight hours - but will notice it slowly changing to all snow by the morning. This is where the secondary low takes hold and has snow falling over the area almost all day. Mix/rain line will gradually shifts south-southeast throughout the day. For NYC, that changeover may not happen until 4-5pm. Any precip before then should be mainly rain, which is why accumulations for immediate NYC are cut down. Mid-level centers are on top of us during the day, so 850mb temps are mild stretching from NJ shore to LI into CT.

The CCB that develops - it will develop - will drop additional snowfall over a localized region. Where I have the yellow circle there is the possibility of additional snow, maybe as much as 6" in some spots. Worse conditions will be from 4pm-12am with moderate to heavy snow falling.

Snow will come to an end between 4-5am on Tuesday.

Have fun tracking everyone!!

4 to 8?! Sign me up nws saying 2 to 4. Do you realize you included nyc in the 4 to 8? Did you mean to do so? If that circle area inches a few miles west another 6 inches possible would be incredible but not counting on it. Why is nws so non interested and has wwa for us from beginning to end. Do you think possible southern Westchester gets a wsw? 4 to 8 is wsw criteria I believe. As usual no prep going on. I have haunting memories of last year.

Raining 28

Light freezing rain/sleet starting here on LI. Temp 32.1

21 degrees light sleet.Looks like we go right to the mix, no snow today.

Impressive cold pocket

Light sleet, 29.5°

Tiny little styrofoam-looking beads falling and bouncing off the ground, and skating. Very slippery out with just that powdered sugar look on the ground. Seven degrees away from today's forecasted high of 31. The precipitation is varying in intensity, coming and going.

Headed back from eastern CT nothing over here obviously yet report from yonkers is nothing just cold.

Light sleet and freezing rain 29°

Temperature actually falling now in Clinton - light freezing rain

24 degrees in Stillwater NJ at 1190 ft altitude,[im try g]https://i.servimg.com/u/f68/18/88/63/92/4f4a9a10.jpg[/img]

sleeting and raining EVERYTHING HIT GROUND FREEZES. Very slick !
Snow plow coming by and putting down salt, this is going to get interesting

27° in Wayne. No current precipitation, but flurries fifteen minutes ago

Ice in yonkers the San Francisco of ny it's not good if we get any ice look up yonkers cars ice on YouTube. Lots crazy videos.

I am surprised that the temp dropped three degrees in 20 min. Now 21

The sleet has effectively made driving a no-go. So little and just so slippery out

Precip running into very dry air, cooling the temps

I'm surprised at 21 degrees it's sleet normally would be snow.

23 and mostly cloudy in Hyde Park. Nothing yet.

Just some on and off light sleet 28 degrees I think we're going to have to wait for the better lift to come in around noon time which could change precipitation over to snow for a while but definitely looks I icy here

light rain and 33*

29 degree mix of freezing rain and sleet.  Pockets of warm air between 1000 - 1500 feet.  

Below the purple line i don't expect temperatures to go above freezing for several hours. Be very careful of the ice!

23.5 and light sleet.

What a bummer.

Jman just rain here at 30

When is the change over to snow happing?

HRDPS (short range Meso model) is showing a prolonged snow event with lots of banding NW of 95. If the location of the low is far inside the BM as much as it depicts that makes sense.
