AREAS AFFECTED...SERN VA...ERN NC
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 271529Z - 271630Z
LATEST WV IMAGERY CLEARLY DEPICTS A WEAK SHORTWAVE TROUGH LIFTING
NEWD ACROSS SC TOWARD MIDDLE ATLANTIC REGION. RADAR TRENDS SUPPORT
THIS FEATURE WITH DEEPENING CONVECTION OVER SC...AND ALONG AN AXIS
OF DEEPER CONFLUENCE STRETCHING ACROSS CNTRL NC INTO SERN VA.
THUNDERSTORMS ARE BEGINNING TO DEVELOP OVER SERN VA WITHIN THIS
ZONE...AND SHOULD SOON DEVELOP SWWD AS SHORTWAVE ENHANCES
CONVERGENCE. AS TEMPERATURES WARM INTO THE LOWER 80S THERE IS
GREATER CONFIDENCE IN ROBUST UPDRAFT DEVELOPMENT. SHEAR VECTORS
FAVOR ORGANIZED LINE SEGMENTS WITH POSSIBLE ISOLATED SUPERCELLS.
DAMAGING WINDS ARE THE MOST LIKELY SEVERE THREAT.
