AREAS AFFECTED...DELMARVA SWWD INTO THE NC PIEDMONT

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 111633Z - 111800Z

CORRECTED FOR TYPO THIRD PARAGRAPH

TSTMS ARE EXPECTED TO INCREASE IN COVERAGE AND INTENSITY THIS
AFTERNOON WITH GREATEST SEVERE WEATHER THREAT EXPECTED ACROSS THE
DELMARVA AND ADJACENT VA PIEDMONT.

LATEST REGIONAL RADAR MOSAIC INDICATES TSTMS DEVELOPING ALONG THE
BLUE RIDGE FROM N OF ROA TO N OF HKY. DOWNSTREAM AIRMASS ACROSS THE
VA/NC PIEDMONT REGION HAS WARMED INTO THE 80S...AND WHEN COUPLED
WITH DEWPOINTS IN THE UPPER 60S TO MID 70S...IS RESULTING IN MLCAPES
OF AROUND 1500 J/KG. TSTMS ARE EXPECTED TO INCREASE IN COVERAGE AND
INTENSITY THIS AFTERNOON AS THEY MOVE/DEVELOP EWD INTO THIS
INSTABILITY AXIS.

IT APPEARS THAT THE GREATEST SEVERE WEATHER POTENTIAL WILL EXIST
FROM THE DELMARVA REGION SWD ACROSS THE VA PIEDMONT WHERE CLOSER
PROXIMITY TO APPROACHING MID/UPPER-LEVEL JET STREAKS WILL RESULT IN
STRONGER WIND SHEAR PROFILES. CONVECTIVE TRENDS WILL BE MONITORED
AND A WW MAY BE REQUIRED IN THE NEXT HOUR OR TWO FOR NRN PORTIONS OF
THE DISCUSSION AREA.
