Latest NAM shows the inconsistency of the modeling of Tuesday’s snow. The NAM has moved the snow to the afternoon and evening on Tuesday. Additionally, the secondary low develops far from the coast.

The QPF is about 0.48 inches water, but I wouldn’t hang your hat on that number.   Despite the QPF,  I’m thinking 1-3 inches snow by late Tuesday evening.   This “storm” could just fizzle out.

11 pm: Latest GFS maintains a similar QPF, but has the heaviest snow before daybreak on Tuesday. These are large differences and model inconsistency in this time frame suggests that neither is correct. This snow remains low confidence.
