But just based on the hype I expect most things to be closed on Monday. It’s supposed to be like 10 degrees again tomorrow night. And places north and west where a foot of snow or more will fall all districts will be closed 1 Link to comment Share on other sites More sharing options...

Even with the NAM that seems to be what we’re looking at. But I agree, definitely can’t discount it. I don't think it does. I noticed it halts the accumulation (at least on kuchera) as soon as we flip to sleet Link to comment Share on other sites More sharing options...

Bxstormwatcher360 Posted January 24 Share Posted January 24 The navgem and 557ww model have been all snow since the get. Little known but the most consistent modeling so far. They both show all levels at or below freezing for the duration of the event. Good to see ukie joined them after being in the warm camp. Link to comment Share on other sites More sharing options...

Winterweatherlover Posted January 24 Share Posted January 24 Best Guess Local best guess predictions, subject to change based on slight deviations in track Sandy Hook 7 inches than sleet/zr JFK 7 inches then sleet/zr NYC 8 inches then sleet Yonkers 10 inches then sleet HPN 12 inches then snow/sleet mix North shore LI- 10 inches then sleet Poughkeepsie 18 inches, all snow Link to comment Share on other sites More sharing options...

The oddest thing about the NAM to me is it does not even have crazy rates ahead of the changeover line. The frontogenesis is semi dislodged from the area where that would occur which may be why. But every other model shows insane rates 2-3 hours before that change occurs...so if the NAM is wrong on that idea the changeover may be delayed 2 Link to comment Share on other sites More sharing options...

Rmine1 Posted January 24 Share Posted January 24 Would you rather waste precip waiting for the column to cool enough to support snow, or to what we may be facing tomorrow evening? I most certainly rather have the snow on the ground before a possible mix, that will still be frozen. Far from ideal, but we all know that “ideal” snowstorms, especially for LI, are a rarity. We’ll all love the winter wonderland that won’t be melted away the following day, also very typical of recent winters. 1 Link to comment Share on other sites More sharing options...

RU848789 Posted January 24 Share Posted January 24 43 minutes ago, NEG NAO said: The ice accumulation potential and very cold temps make it a winter storm warning If meteorologists weren't so fixated on snow depth, but instead focused on frozen mass, 2" of sleet, alone, which is equivalent in frozen mass to 6" of 10:1 snow, would qualify for a warning. Same impacts on transportation and shoveling/plowing, plus it melts more slowly due to the much lower surface area to volume ratio. It doesn't have visibility issues, though, and it's not as pretty, but it's just about as impactful on the public. Link to comment Share on other sites More sharing options...

donsutherland1 Posted January 24 Share Posted January 24 7 minutes ago, wilton_wx said: Thoughts on HREF? For reference, here's the map though 1/26 0z. Typically, if one reduces the amounts by a category at this lead time, it's estimate is pretty good. As snow will continue to fall in parts of the Hudson Valley after 0z, it's current listing of 12"-15" there is reasonable. I think there will be some 18" amounts there.

Brasiluvsnow Posted January 24 Share Posted January 24 1 hour ago, wxman said: According to Gemini (aka "ask Jeeves"): In 2026, the FV3 model (specifically in its High-Resolution Window and GFS implementations) is noted for a more conservative approach to "warm noses" (elevated layers of air above freezing) compared to older models like the NAM. Warm Nose Prediction Characteristics Layer Integrity: The FV3 tends to maintain colder column integrity better than the NAM. In winter weather setups, it often predicts a weaker or later-arriving warm nose, which can lead to forecasts for more persistent snow while other models might suggest an earlier transition to sleet or rain.

Agree with that i'd always rather a snow to other precip scenario than the other way around near the coast. Link to comment Share on other sites More sharing options...

The NAM seems to be the only hi res model this warm (along with its replacement RRFS) so hopefully that’s a good sign. The hi res RGEM was insane at 6z.
