For what it's worth, Saturday night is still rain, likely but not certain.
8/

Temperatures Sunday during the day right around freezing, dropping into the 20s overnight.
7/

Light snow possible Sunday morning, little to no accumulation. Heavier snow likely Sunday afternoon and evening, tapering off after 8pm and ending after midnight. Wind picks up Sunday night, gusts around 20mph could cause blowing and drifting conditions.

While it is likely to be all snow, there is also uncertainty in how heavy/dense the snow is going to going to be -- the same 0.5" could be 3" of heavy wet snow, or 6" of lighter fluffy snow, and again the storm track determines that.

The closer the center is to us, the more water falls. So the models are forecasting somewhere between 0.2 and 0.6 inches of water to fall from noon Sunday through just after midnight (+/- an hour or two either way).

As I mentioned this morning, the forecast is really a 1" to 6" range (see map below), but now the higher end is looking a lot more possible. Here's the struggle: the models are forecasting the track of this rather narrow storm to run somewhere in a band between Morristown and the Poconos.

Short version, still likely 2" - 4" but with a real upside potential to 6"
