Snow potential Thursday night and Saturday 1/19 to 1/21

Wow...that is very close for comfort, 30 miles north and LI is screwed

I don't think it's as close as it looks. The map is slightly distorted.

The rain/snow line is 50 miles south of Staten Island along the Jersey coast and 75 miles south of the metro further inland in NJ. All of LI is snow with isolated mixing possible in the far SE tip. The rain/snow line always looks close to LI offshore because the surface temperatures over open waters are relatively warm. But surface temperatures over land are plenty cold and I think there is also margin for a warmer solution.

The models are trending too far south for my liking. I think Cold High Pressure is too far south and that could help suppress the storm a bit and put the axis of the heavy snow just south of NYC. Coming in drier is starting to worry me alittle. Possibly the snow will go too fast that it may come in as vigra since it will be too dry. The timing and the placement of the high needs to perfect to produce the overrunning snow storm. It is becoming more likely based on the model trends it will go too far south to bring the substantial amount of snow than go too far north the snow will change to rain. The more southerly track will cause a weaker storm and that means the storm will have less energy and moisture to work to go much north. The GFS/NAM/GGEM looked perfect to me. 2-4" I will take any day and even an inch would be good enough.

I can't believe it's been almost 3 months since NYC got 2.9"... What's even funnier is that NYC may get the same amount of snow as they did on 10/29.. Yet it will stick a lot better this time around..

kind of like the 70's and early 80's Mets fans that were happy just not to finish in Last place for the season. ;)

Light rain on Sandy Hook, light snow on Coney Island, heavy snow in between. :)

Nam was a little warm for the area. The Euro is great for the area. These storms tend to trend north at the last second. I doubt this will trend really north since we have a -PNA.

relax. You'll get 2-5 inches.

A storm further south means that the vort driving the storm is weaker, and therefore the lift and associated precip is a little weaker. Still, this winter it's impossible to complain about a 3-6" type of storm. Should easily be sufficient to generate advisories at least. Even with a slight north bump at the end most of us are good to go.

If I'm reading the models and comments correctly, it ooks like Central Jersey (most of Middlesex/Somerset/Hunterdon/Mercer), perhaps even including the northern Monmouth County coast, could be the bullseye, i.e., getting the heaviest precip without changing over to rain, except maybe at the very end, which doesn't really matter. That would be rare, although it did happen a few times over the past 2 years. I'd be happy with 2-4" of the white stuff...
