NAM model simulating some light accumulated precipitation south of D.C. as of 4 a.m. Saturday morning. Note the freezing line is well to the west, near I-81. (

There are two problems for getting snow Friday night:

1) The bulk of the moisture is passing to the south
2) Temperatures, while cooling sufficiently at upper levels for a brief period of snow, will be well above freezing at the surface (35+).

Maybe, over the northern neck of Virginia and southern Maryland, where precipition is a bit steadier, the rain mixes with snow before ending with no accumulation. That’s the most I expect.

An upper level disturbance (the orange and red shaded area) streams in from the northwest Sunday morning. (GFS model, valid 7 a.m.) (

I’m trying hard to find snow, and just don’t see much promise - whether it’s the short term or the long term.
