If this comes in hot and heavy with a couple hours of heavy snow it could leave a little on the ground. My zone forecast says snow maybe heavy at times, so that would make sense with that idea.
6z euro warmed in the 850 levels at 15z versus 00z run at 18z is about 1° warmer as well overall.
For that matter seems 6z warmed a little for a bunch models.
Northern long Island fairs far better at marginal winter time events and holding onto frozen precip a little longer versus south lie. Will all depend on on fast temps rise I guess.
Finally found something but here's Wednesday record highs for a bunch of areas.
KLGA: 66-1985
KJFK: 62-1990
Islip: 61-2012
Central Park: 72-1874 (wow)
Upton: 50-2017
Newark: 68-1985
Bridgeport: 60-2012
Haven't had time to check but I'm guessing there won't be much wind otherwise long Island areas still will be cold unfortunately thanks to that marine influence.
