You'll be fine. Even once it snows, it's going to take some time to cool the road surfaces enough for snow to stick. After 4 PM I'd stay off the roads. I have friends coming in from Sunday River (8.5 hour drive) They will be back by 4:30 tomorrow
I'm going to try and get into IBSP Monday (research purposes). I feel somewhere between there and Squan will be the bullseye. Matter of finding somewhere that doesn't have massive drifts
If 18z trends hold on with the 0z suite I'd say the odds for warning level snows increase significantly for NYC.
Still, I'm cautious. We've had the rug pulled out beneath us before.
