SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
108 PM EDT TUE JUL 29 2003

...SEVERE THUNDERSTORMS POSSIBLE ACROSS EXTREME NORTHEAST GEORGIA
AND THE WESTERN CAROLINAS...

THUNDERSTORMS WILL INCREASE IN COVERAGE AND INTENSITY THROUGHOUT
THE AFTERNOON. A MOSTLY SUNNY START TO THE DAY HAS RESULTED IN A
VERY UNSTABLE ATMOSPHERE. AS A COLD FRONT APPROACHES FROM THE
NORTHWEST...AND A POTENT UPPER LEVEL DISTURBANCE ROTATES ACROSS
THE REGION THIS AFTERNOON...THERE IS THE POTENTIAL FOR SOME OF
THE THUNDERSTORMS TO BECOME SEVERE. THE MAIN SEVERE WEATHER THREAT
THROUGH EARLY EVENING WILL BE DAMAGING WIND GUSTS TO NEAR 70 MPH.
THUNDERSTORMS SHOULD WEAKEN WITH THE LOSS OF DAYTIME HEATING.

WITH A WEAK WIND FLOW ALOFT...ANY THUNDERSTORMS THAT DO DEVELOP ARE
EXPECTED TO MOVE SLOWLY...AND COULD PRODUCE AT LEAST A COUPLE OF
INCHES OF RAIN IN ANY ONE LOCATION. STANDING WATER ON ROADS...AND IN
POOR DRAINAGE AREAS IS LIKELY WHEREVER THUNDERSTORMS LINGER FOR LONG
PERIODS. STREAMS...CREEKS AND RIVERS COULD SEE QUICK RISES ACROSS
THE REGION...ENHANCING THE POSSIBILITY OF LOCALIZED FLOODING.

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

STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE MEDIA OUTLET FOR
THE LATEST UPDATES CONCERNING THIS POTENTIAL SEVERE WEATHER
SITUATION.
