From RAH:
As the low center pushes off the Carolina coast and deepens, banded
precip is possible to its NW, over the
NC Piedmont. As the column
cools with both
deepening CAA and increasing rates, a mix then
switchover to mostly snow is expected. While surface temps initially
would seem to not support much accumulation (
esp given observed
soil temps in the 40-45F range), a dusting to close to an inch appears
possible on grassy surfaces over the N Piedmont, with the higher end
of this range occurring where rates are particularly intense. Precip
should trend out overnight as the low moves further offshore, exiting
NE sections last just prior to daybreak. Expect lows from around
30 N to the mid 30s SE. Predicted snowfall amounts at this time appear
to fall just shy of an advisory, but will keep an eye on upcoming model
precip area and
QPF and their vertical
thermal structures to determine
the potential for banding that could increase totals. -GIH
