VALID 021329Z - 021500Z

THREAT FOR LOCALLY STRONG / SEVERE WIND GUSTS APPEARS TO EXIST...AND
WILL PERSIST THROUGH APPROXIMATELY MIDDAY.

WITH RELATIVELY MOIST /60S DEWPOINTS/ BOUNDARY LAYER ACROSS SERN VA
AND ADJACENT NERN NC...AIRMASS HAS BECOME MINIMALLY UNSTABLE. 
LIMITED DESTABILIZATION MAY CONTINUE AS COOLER MID-LEVEL
TEMPERATURES SPREAD EWD ASSOCIATED WITH APPROACHING MID / UPPER
TROUGH.  HOWEVER...DESTABILIZATION POTENTIAL WILL BE LIMITED DUE TO
NNEWD ADVANCE OF PRE-FRONTAL CLOUDS / PRECIPITATION.

NONETHELESS...VERY STRONG LOW-LEVEL WIND FIELD -- AS REVEALED BY
MORNING RAOBS AND AREA VWPS -- SUGGESTS THAT AT LEAST SOME THREAT
FOR DAMAGING WINDS WITHIN BROKEN / FRONTAL CONVECTIVE LINE AS IT
SHIFTS EWD ACROSS THIS REGION. CURRENT EXTRAPOLATION SHOWS THAT
THIS LINE SHOULD CLEAR THE COAST BY MIDDAY / EARLY
AFTERNOON...EFFECTIVE ENDING ANY SEVERE THREAT.
