From the NWS forecast discussion today, I think that it sums things up pretty well.
With most guidance lifting the upper low through the carolinas, becoming
more negatively tilted, this favors some precipitation in our
area. The biggest issue for winter lovers, outside of the
mountains, is the fact that this storm has trended so much
slower. The air mass in place at the surface is far from what
one would want to produce snowfall. This storm is going to get
all of its cold air aloft from that strong cutoff upper low. A
heavy band will setup somewhere northwest of the low pressure
center, and this is where the best chance for snowfall would
occur outside of the mountains. But even that may not be enough
for areas along the I-95 corridor, as temperatures look to be
well in the upper 30s to low 40s. The best chance for snowfall
lies along and west of the Blue Ridge, especially at higher
elevations. This matches the ensemble means at this point as
well, which paint a solid stripe of accumulating snowfall in
that area. Snowfall farther east can certainly not be ruled out
though at this time, but probabilities just aren`t looking as
promising. As always, consult weather.gov/lwx/winter for the
latest winter weather forecast updates. This storm system,
having trended slower in recent days, is still around 4 days
out, so many things can change in that amount of time. As said
in previous forecasts, cutoff upper lows are notoriously
difficult to handle, and any small deviation in track/speed
could spell big changes to the forecast.
