AREAS AFFECTED...PORTIONS OF KY/TN/NC/SC/GA

CONCERNING...SEVERE THUNDERSTORM WATCH 373...374...377...

VALID 302033Z - 302230Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
373...374...377...CONTINUES.

SUMMARY...THE RISK FOR SVR TSTMS CONTINUES ACROSS THE SEVERE
THUNDERSTORM WATCH AREAS.

DISCUSSION...TSTMS CONTINUE INCREASING IN COVERAGE AND INTENSITY
ACROSS THE REGION FROM PARTS OF MIDDLE TN TO THE SRN APPALACHIANS TO
THE PIEDMONT OF THE CAROLINAS. A MORE PROMINENT CONVECTIVE CLUSTER
ORGANIZING INTO A FORWARD-PROPAGATING LINE IS CROSSING PARTS OF
CNTRL/SRN SC AND SERN GA. MODERATE INSTABILITY AIDED BY SFC TEMPS IN
THE LOWER 90S AMIDST A MOISTURE-RICH PBL WILL ALLOW THIS ACTIVITY TO
CONTINUE SPREADING TOWARD THE SC COAST DURING THE NEXT FEW HOURS.
THE RISK FOR DMGG WIND GUSTS AND PERHAPS HAIL COULD ACCOMPANY THIS
ACTIVITY. IF CONFIDENCE WERE TO INCREASE THAT STRONGER ACTIVITY
DEVELOPS NEWD INTO NERN SC AND SERN NC...THEN A NEW WW MAY BE NEEDED
IN THESE AREAS. ADDITIONAL MORE ISOLATED TO SCATTERED CONVECTION
CONTINUES WWD INTO CNTRL GA TO MIDDLE TN. THE PRESENCE OF 1000-2000
J/KG OF MLCAPE WHERE CONVECTIVE OVERTURNING HAS NOT BEEN ABUNDANT
WILL CONTINUE TO ENCOURAGE ORGANIZATION OF MULTICELL CONVECTIVE
CLUSTERS GIVEN 20-30 KT OF EFFECTIVE BULK SHEAR. ISOLATED TO WIDELY
SCATTERED DMGG WIND GUSTS AND PERHAPS HAIL WILL BE OF CONCERN WITH
THESE TSTMS.
