AREAS AFFECTED...PARTS OF THE CAROLINAS INTO NORTHEAST GA
CONCERNING...SEVERE THUNDERSTORM WATCH 459...
VALID 252040Z - 252215Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 459
CONTINUES.
SUMMARY...THE DAMAGING WIND THREAT MAY GRADUALLY INCREASE INTO THE
EARLY EVENING. ISOLATED HAIL ALSO REMAINS POSSIBLE.
DISCUSSION...EXTENSIVE CONVECTION IS ONGOING LATE THIS AFTERNOON
ACROSS PARTS OF EASTERN NC, WITH ADDITIONAL STORMS IN WESTERN NC,
AND DEVELOPING CUMULUS INTO PARTS OF SC AND EAST-CENTRAL/NORTHEAST
GA. ADDITIONAL STORM DEVELOPMENT IS POSSIBLE INTO EARLY EVENING,
WITHIN A VERY UNSTABLE (MLCAPE OF 3000-4000 J/KG) ENVIRONMENT.
GENERALLY WEAK DEEP-LAYER SHEAR CONTINUE TO HAMPER STORM
ORGANIZATION, BUT THE STRONG INSTABILITY AND STEEP MIDLEVEL LAPSE
RATES WILL CONTINUE TO SUPPORT VIGOROUS UPDRAFTS.
OUTFLOW IS GRADUALLY EXPANDING ACROSS EASTERN NC, AND THERE MAY BE
SOME TENDENCY FOR A LOOSELY ORGANIZED STORM CLUSTER TO PROPAGATE
SOUTH/SOUTHWESTWARD WITH TIME, AS OUTFLOW IMPINGES UPON A HOT AND
VERY MOIST ENVIRONMENT. A SIMILAR EVOLUTION COULD TAKE PLACE WITH
ONGOING STORMS ACROSS WESTERN NC. THIS COULD LEAD TO MORE
CONCENTRATED AREAS OF DAMAGING WIND WITH TIME. THE STRONGEST
UPDRAFTS WILL ALSO CONTINUE TO BE CAPABLE OF PRODUCING ISOLATED
HAIL.
