PB GFI Posted December 24, 2013 Share Posted December 24, 2013 There could be some treacherous driving as everything will freeze solid behind the Arctic front.

bluewave Posted December 24, 2013 Share Posted December 24, 2013 Should have stayed in Laurel Hollow tonite I remember one of these squalls back in the 80's that came in during the afternoon and the sky got as dark as a summer thunderstorm with flakes as big as quarters and low visibilities peaking for about 10-20 minutes.

weathermedic Posted December 24, 2013 Share Posted December 24, 2013 Looks like northern Nassau/western Suffolk get the most out of this tonight as per posted model pics Link to comment Share on other sites More sharing options...
ag3 Posted December 24, 2013 Share Posted December 24, 2013 People need to be careful. Models have NYC above freezing and in the mid to upper 30s as the precip moves in. LI is close to 40 degrees. While it will cool down for whoever gets under the band, it will have a very hard time accumulating for the 1st half hour or so and this "event" has very limited precip. The actual accumulating snow will be very limited to a small area and a lot of areas will begin as rain/slop. Link to comment Share on other sites More sharing options...

Those temps are probably overdone. 4km NAM and 12km NAM have temps in the to mid 30's for highs, and low 30's when the precip arrives. A lot of models over do the surface warmth on LI.

Coastalfront Posted December 24, 2013 Share Posted December 24, 2013 any accumulation will likely be just north of the city, surface temps will be warm as stated above. Link to comment Share on other sites More sharing options...
bluewave Posted December 24, 2013 Share Posted December 24, 2013 The spots that get under the best band will probably plunge from the mid-30's to around freezing in a few minutes enhancing the icy road threat as any initial slush will freeze solid behind the front. The CAA is very strong with the steep lapse below 800 mb. Link to comment Share on other sites More sharing options...

The snowfall will accumulate anywhere the rates are heavy enough as the dews will be in the teens and surface temps plunge in a few minutes to near freezing.

TWCCraig Posted December 24, 2013 Share Posted December 24, 2013 Temps crash fast on the 12z NAM. Decent rates over LI at that time, before precip, temps are around 34, when heaviest precip arrives, temps drop into the upper 20s. Link to comment Share on other sites More sharing options...
FreeRain Posted December 24, 2013 Share Posted December 24, 2013 any accumulation will likely be just north of the city, surface temps will be warm as stated above. 850s temps are cold. Don't see any accumulation problems on LI. More worried about missing out on such a narrow band. Link to comment Share on other sites More sharing options...
hooralph Posted December 24, 2013 Share Posted December 24, 2013 Good to hear from you, man. Hope all is well. All is indeed good. Love life in NYC. Just need a dump of fresh powder in Central Park. I didn't make it out after the snows this week and while running in the park Sunday in the 70 degree temps was shocked to see that the ponds had been frozen.
