NWS take on early next week,
One of the recent runs of a major weather model (00z GFS) suggested
a substantial amount of accumulating snow across much of the area
Sunday night. This type of storm, however, doesn`t seem to fit with
the overall weather pattern (fast-moving cold front plowing offshore
with a subtropical ridge off the Southeast coast usually aren`t
favorable for significant lower elevation snow in the Mid-Atlantic).
Several other model simulations since have keyed in on what may be
more likely: a brief period of wet snow on the backside of the
strong cold front Sunday night. Widespread, prolonged/plowable snow
seems very unlikely at the moment given (1) very mild temperatures
are expected beforehand, and (2) dry air will chase the storm
offshore before precipitation can fall as snow for too long. Given
the anticipated warm temperatures beforehand, it will be difficult
for snow to stick (if it falls at all). Regardless of any wintry
precipitation, there is much higher confidence in gusty winds of 30-
35+ mph and wind chill temperatures dropping into the 20s and teens
Sunday night into Monday morning (around 0 for the higher
elevations where stronger, damaging wind gusts are possible).
The colder weather looks to last about 36 to 48 hours before
temperatures begin to moderate once again by the middle of next week.
