AREAS AFFECTED...TENNESSEE VALLEY INTO CENTRAL CAROLINAS
CONCERNING...SEVERE THUNDERSTORM WATCH 239...240...242...
VALID 082311Z - 090015Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 239, 240,
242 CONTINUES.
SUMMARY...SEVERAL CLUSTERS OF STRONG TO SEVERE THUNDERSTORMS WILL
CONTINUE TO AFFECT THE REGION THROUGH THE EARLY EVENING, BEFORE
DIURNAL COOLING WEAKENS STORMS. LARGE HAIL AND LOCALLY DAMAGING
WIND GUSTS ARE THE PRIMARY CONCERN.
DISCUSSION...RECENT REGIONAL RADAR IMAGERY CONTINUES TO SHOW
CLUSTERS OF THUNDERSTORMS FROM MIDDLE TN AND NORTHERN AL INTO
SOUTHERN WV. ANOTHER BROKEN LINE OF STORMS EXTENDS FROM
SOUTH-CENTRAL VA INTO UPSTATE SC. SEVERAL OF THESE STORMS CONTINUE
TO SHOW LOOSELY-ORGANIZED ROTATING UPDRAFTS CAPABLE OF HAIL AND
GUSTY WINDS. ACTIVITY WILL LIKELY BEGIN TO DIMINISH IN INTENSITY
DURING THE NEXT 1-2 HOURS AS DIURNAL COOLING OCCURS AND INSTABILITY
WEAKENS.
ONE AREA THAT MAY SEE CONTINUED CONVECTIVE DEVELOPMENT WILL BE
ACROSS SOUTHERN NC INTO PARTS OF NORTHERN SC - IN VICINITY OF A WEAK
MID-LEVEL SHORTWAVE TROUGH SEEN IN WATER VAPOR IMAGERY. CAPE VALUES
OF 1500+ J/KG AND SUFFICIENT WESTERLY FLOW ALOFT MAY MAINTAIN A RISK
OF SEVERE STORMS FOR A FEW MORE HOURS.
