NWS STORM PREDICTION CENTER NORMAN OK
1238 PM CDT WED MAY 26 2004

AREAS AFFECTED...ERN KY/WV/WRN AND CNTRL VA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 261738Z - 261915Z

TSTMS ARE EXPECTED TO INCREASE IN COVERAGE AND INTENSITY THROUGH THE
AFTERNOON HOURS. CONVECTIVE TRENDS WILL BE MONITORED AND A WW MAY BE
REQUIRED.

TSTMS HAVE GRADUALLY INCREASED OVER THE MOUNTAINS OF FAR WRN VA OVER
THE PAST HOUR FROM GILES COUNTY SWD INTO WASHINGTON COUNTY.
MEANWHILE...LONG-LIVED SUPERCELL WITH A HISTORY OF LARGE HAIL
PRODUCTION WAS LOCATED OVER MASON COUNTY WV MOVING ESEWD AT 40KTS.
THOUGH HIGH CLOUDINESS IS TENDING TO OVERSPREAD REGION FROM THE
W...PRESENCE OF DEWPOINTS IN THE 60S AND PARTIAL SUNSHINE IS
CONTRIBUTING TO POCKETS OF MODERATE INSTABILITY WITH MLCAPES
APPROACHING 1000-1500 J/KG. THIS COUPLED WITH STRONG WIND SHEAR
PROFILE OBSERVED CURRENTLY ON CHARLESTON WV VWP SUGGESTS THE
POTENTIAL FOR ORGANIZED TSTMS...INCLUDING SUPERCELLS WITH LARGE HAIL
AND DAMAGING WINDS. 

EXPECT WRN VA STORMS TO CONTINUE TO INTENSIFY AS THEY PROGRESS EWD
THIS AFTERNOON. ADDITIONAL TSTMS CURRENTLY DEVELOPING DOWNSTREAM
FROM ONGOING MCS WILL LIKELY MOVE OUT OF WW 293 WITHIN THE NEXT
COUPLE OF HOURS. THUS...A NEW WW MAY BE REQUIRED E OF WW 293.
