AREAS AFFECTED...WEST VIRGINIA INTO CENTRAL AND SOUTHERN PARTS OF
VIRGINIA
CONCERNING...SEVERE THUNDERSTORM WATCH 247...
VALID 272254Z - 280100Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 247
CONTINUES.
SUMMARY...ISOLATED DAMAGING WIND GUSTS REMAIN MOST LIKELY ACROSS
PORTIONS OF CENTRAL AND SOUTHERN VIRGINIA OVER THE NEXT COUPLE OF
HOURS.
DISCUSSION...AS OF 22:45 UTC A BROKEN BAND OF STRONG TO SEVERE
STORMS WAS ONGOING FROM NORTHEAST OF ROANOKE TO WEST OF RICHMOND,
WITH A STORM MOTION OF 282/38 KT. LATEST SURFACE ANALYSIS AND
VISIBLE SATELLITE INDICATE A CORRIDOR OF LESS-DENSE CLOUD COVER TO
THE SOUTH OF THE ONGOING STORMS, WHERE TEMPERATURES REMAIN IN THE
LOW/MID 80S WITH DEWPOINTS IN THE UPPER 60S TO LOW 70S. RESULTANT
MLCAPE IS ESTIMATED IN THE 1000-1500 J/KG RANGE WITHIN THAT CORRIDOR
WITH RELATIVELY STEEP LOW-LEVEL LAPSE RATES. AREA VWPS INDICATE
WESTERLY WINDS ABOVE 1 KM AGL WITH 30-35 KT OF DEEP-LAYER SHEAR,
WHICH WILL CONTINUE TO SUPPORT SOME STORM ORGANIZATION FOR THE NEXT
COUPLE OF HOURS WITH THE PRIMARY HAZARD BEING LOCALLY DAMAGING WIND
GUSTS.
COOLING BOUNDARY-LAYER TEMPERATURES AND A CORRESPONDING INCREASE IN
AIR MASS STABILITY ARE EXPECTED TO LEAD TO AN INCREASINGLY SPORADIC
SEVERE THREAT BY 01Z.
