...SEVERE WEATHER OUTLOOK...

SURFACE LOW PRESSURE WILL REMAIN NEARLY STATIONARY ACROSS THE
WESTERN CAROLINAS THROUGH THE AFTERNOON HOURS. MEANWHILE... A STRONG
UPPER LEVEL DISTURBANCE WILL SLOWLY MOVE EAST... INTO SOUTHWEST
VIRGINIA BY THIS EVENING.

IT NOW APPEARS THAT THE GREATEST INSTABILITY WILL BE EAST OF THE
SURFACE LOW CENTER... ACROSS CENTRAL AND EASTERN NORTH CAROLINA.
HOWEVER... A FEW THUNDERSTORMS MAY STILL REACH SEVERE LIMITS...
PRODUCING STRONG WINDS AND LARGE HAIL... ALONG AND EAST OF A LINE
FROM CHARLOTTE TO YORK... UNION... LAURENS... ABBEVILLE AND
ELBERTON.

CLOSER TO THE UPPER LEVEL LOW... ACROSS THE MOUNTAINS OF THE WESTERN
CAROLINAS... THERE WILL BE A LITTLE MORE SUN THIS AFTERNOON... ALONG
WITH COLDER TEMPERATURES IN THE UPPER LEVELS OF THE ATMOSPHERE.
THEREFORE... ISOLATED SEVERE THUNDERSTORMS WILL ALSO BE POSSIBLE
THIS AFTERNOON AND EVENING ACROSS THE MOUNTAINS OF THE CAROLINAS.

IN BETWEEN THESE TWO AREAS... ACROSS MUCH OF THE FOOTHILLS AND
WESTERN PIEDMONT... LOW CLOUDS ARE EXPECTED TO RESULT IN TOO LITTLE
HEATING FOR THERE TO BE MUCH OF A SEVERE THREAT THIS AFTERNOON.
HOWEVER... THERE WILL STILL BE SCATTERED SHOWERS AND THUNDERSTORMS
ACROSS ALL THE WESTERN CAROLINAS AND NORTHEAST GEORGIA.

SPOTTER GROUPS SHOULD BE PREPARED TO ACTIVATE QUICKLY THIS AFTERNOON
AND THIS EVENING. DISPATCHERS SHOULD ENSURE COUNTY EMERGENCY
MANAGEMENT OFFICIALS ARE AWARE OF THIS INFORMATION.
