Still snow and sleet with frigid temperatures to start, but when you can't just say it's cold when the entire dynamics change and it's entirely possible that a large chunk of coastal areas get to or above freezing. Maybe the eastern tip of LI changes to rain but I highly doubt anyone else does unless we see prolonged onshore winds given the severity of the cold air coming in. I could see freezing rain happening if we get a shallower cold layer at the surface. Bottom line is hopefully this NAM run is wrong. 1 Link to comment Share on other sites More sharing options...

weatherpruf Posted January 23 Share Posted January 23 8 minutes ago, NJwx85 said: That NAM run wasn’t great but we’re still 36hrs out and things are going to continue to fluctuate. Any further North and there’s going to be some serious ZR issues for Southern parts of the area. Even as is, the NAM has about a 30 mile swath of 0.10 to 0.20 more or less over 95 with closer to a half inch South of Philly and into DC. they could also get plain rain in the southern parts, but i don't know if that would help.

eduggs Posted January 23 Share Posted January 23 11 minutes ago, Tar Heel Snow said: FWIW, on RRFS, the sleet line only barely brushes LI but keeps the city all snow The RRFS is snowier than the NAM for sure, but the RRFS also shifted northward with the heaviest snow and the thermals. 12z had better ratios and was a mid-HV down to near NYC jack. 18z has it up near ALB with heavy snows to the NY border. Obviously it will shift around somewhat but it's disappointing not to see a clear colder/south trend at 18z so far. 1 Link to comment Share on other sites More sharing options...

It’s not just the NAM, though NAM is the least snowy of the bunch If you add 1-2" of sleet that counts as accumulation too but I always thought 12" for NYC which they have now and 14" yesterday was too aggressive. I'd go with 12" maybe in Yonkers and 8" in SI/Rockaway. 1 Link to comment Share on other sites More sharing options...

NJwx85 Posted January 23 Share Posted January 23 18z ICON is one hell of an ice storm South of I-80. Plain rain on the Jersey coast up to about Tom’s River. Link to comment Share on other sites More sharing options...
Tar Heel Snow Posted January 23 Share Posted January 23 Shoot, sorry everyone. Not sure why pivotal defaulted to showing the old run when I clicked, but the 18z RRFS was a lot messier about 8-9 hours of snow and then 8-9 hours of IP/ZR. Ugh.

This type of storm doesn't jackpot NYC to Philly. These do best along I-90. This is the storm where Boston catches up and probably surpasses us at least along the coast for seasonal snow-wouldn't be surprised if they get 16-18". We're lucky we have this high pressure dome in place to provide an overrunning surface so we get the initial thump of snow down into VA, otherwise this would be the usual SWFE couple inches to rain/sleet. But is something like the NAM possible here with a stronger primary low-sure. Even that though would probably be 4-6" snow then a couple more inches of sleet-however it would also bring the dryslot in quicker. 1 Link to comment Share on other sites More sharing options...
