from the NWS/Storm Prediction Center

...CAROLINAS THROUGH MID ATLANTIC...

THE 12Z WEDNESDAY RAOB DATA SHOWED ONLY A SHALLOW MOIST LAYER WITH
LOW 60S DEWPOINTS NEAR THE SURFACE ACROSS COASTAL FL AND SC. AS A
RESULT DEWPOINTS HAVE RECENTLY MIXED DOWN IN THE 50S IN THESE AREAS.
HOWEVER...THE BOUNDARY LAYER OVER THE GULF STREAM CONTINUES TO
MODIFY...AND PERSISTENT SLY LOW LEVEL FLOW WILL LIKELY ADVECT LOW
60S DEWPOINTS NWD THROUGH THE CAROLINAS AND PARTS OF VA BY THURSDAY
AFTERNOON. THIS ALONG WITH DIABATIC HEATING WILL RESULT IN MLCAPE
FROM 800-1200 J/KG DURING THE AFTERNOON. A FEW STRONG-SEVERE STORMS
MAY DEVELOP IN THIS REGION DURING THE DAY WITH A PRIMARY THREAT OF
ISOLATED DAMAGING WIND AND POSSIBLY SOME HAIL. THE KINEMATIC
ENVIRONMENT WILL BECOME INCREASINGLY FAVORABLE FOR ORGANIZED STORMS
FROM LATE AFTERNOON AND ESPECIALLY THURSDAY EVENING AS THE UPPER
TROUGH APPROACHES AND LOW LEVEL JET INCREASES. ADDITIONAL STORMS MAY
DEVELOP IN THIS REGION DURING THE EVENING AND OVERNIGHT WITHIN ZONE
OF ASCENT JUST AHEAD OF THE SHORTWAVE TROUGH. DEEP SHEAR AROUND 40
KT AND INCREASINGLY LARGE LOW LEVEL HODOGRAPHS WOULD SUPPORT
SUPERCELLS CAPABLE OF PRODUCING ISOLATED TORNADOES AS WELL LEWP
STRUCTURES CAPABLE OF DAMAGING WIND.
