Im always a little skepitcal when the models are showing something that climo wise almost never happens. I sort of agree with this will end up either mostly snow or mostly rain camp near the coast although I can see with the high placement how the setup the models are showing makes sense but wouldn't really take it that seriously beyond 72 hours.
If the warmer scenario happens I could definitely see crippling icing in the climo spots of Sullivan, Ulster, Passaic and Orange counties.
