Rah thoughts
A cold and dry
air mass is
located across the Midwest, Great Lakes and Central Canada on
Wednesday, not in a favorable location to support a significant
winter storm. But with the upper heights collapsing into the
540s dm range by Thursday morning and sufficient cold
advection
to drop low level thickness values in the 1280s by 12Z Thursday,
some wintry precipitation is possible across the northern tier
of
NC late Wednesday night into Thursday morning as the
precipitation ends. EC
ensemble members from the 00Z run have
bounced back toward the potential for more wintry precip,
especially near the VA border and across the northern Coastal
Plain near KIXA. Still lots uncertainty with the track, and
especially the cold air so will hold off including much in the
way of accumulation. But a couple of hours of wet snow very
late Wednesday night to around daybreak Thursday is possible.
Coordinated with WPC and have introduced a coating of snow
accumulation near the VA border and across the northern Coastal
Plain. Lows will range in the lower to mid 30s.
