.DISCUSSION...
.KEY MESSAGE 1...
As an upr trof swings thru late this aftn and eve, DPVA along with
steepening lapse rates may trigger sct-isold shwrs. Some mixing with
snow is possible especially across the interior. No accums expected.
Residual moisture however may allow for some pockets of black ice to
develop overnight as temps drop into the 20s, depending on the
extent of surface drying.
.KEY MESSAGE 2...
A cold front is progged to move across the region Thursday night
into early Friday. Precip probabilities have increased slightly,
with the most likely timeframe for rain occurring after midnight.
This is when the modeling is coming into agreement with the most
organized lift/convergence coinciding with moisture. The atmosphere
quickly dries out Friday morning behind the cold front. Temperatures
should be able to rise well into the 50s across the area as dew
points drop throughout the day. Dry conditions will continue into
next Monday with high pressure in control. Daytime temperatures will
likely end up well below normal on Saturday in the low to mid 40s,
before slowly trending milder Sunday into next Monday. High
temperatures by next Monday should be in the 50s. The coldest nights
appear to be Friday and Saturday night with temperatures in the 20s
and lower 30s, coldest inland.
