SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1035 AM EDT TUE MAY 22 2001

...SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON ACROSS THE WESTERN
CAROLINAS AND NORTHEAST GEORGIA...

A VIGOROUS COLD FRONT APPROACHING FROM THE WEST LATE THIS MORNING
SHOULD CROSS THE REGION DURING THE AFTERNOON AND EARLY EVENING. THIS
FRONT WILL INTERACT WITH THE WARM AND HUMID AIR ACROSS THE WESTERN
CAROLINAS AND NORTHEAST GEORGIA TO GENERATE THUNDERSTORMS WITH THE
POTENTIAL TO PRODUCE SEVERE WEATHER. SCATTERED THUNDERSTORMS AHEAD
OF THE FRONT THIS MORNING ACROSS NORTH GEORGIA WILL STEADILY BECOME
MORE NUMEROUS AS THE FRONT APPROACHES. A LINE OF THUNDERSTORMS IS
EXPECTED TO DEVELOP JUST AHEAD OF THE FRONT...AFFECTING THE SOUTHERN
APPALACHIANS THROUGH EARLY AFTERNOON...THE FOOTHILLS DURING THE
AFTERNOON...AND THE PIEDMONT THROUGH THE LATE AFTERNOON.

ANY THUNDERSTORMS THAT DEVELOP TODAY WILL PRODUCE BRIEF TORRENTIAL
DOWNPOURS AND FREQUENT LIGHTNING. THE PRIMARY THREAT FOR SEVERE
WEATHER IS DAMAGING WIND GUSTS IN EXCESS OF 60 MPH. ISOLATED LARGE
HAIL IS POSSIBLE AS WELL...AND A BRIEF TORNADO IS NOT OUT OF THE
QUESTION. WHILE SEVERE WEATHER IS POSSIBLE ANYWHERE IN THE OUTLOOK
AREA...PIEDMONT SECTIONS WILL ACHIEVE THE WARMEST TEMPERATURES
BEFORE THE ARRIVAL OF THE FRONT...ALLOWING STRONGER THUNDERSTORMS TO
DEVELOP IN THAT AREA LATE TODAY.

SPOTTER GROUPS SHOULD BE PREPARED TO ACTIVATE QUICKLY THIS AFTERNOON.
A SEVERE WEATHER WATCH IS ANTICIPATED FOR ALL OR PART OF THE AREA BY
EARLY AFTERNOON. DISPATCHERS SHOULD ENSURE COUNTY EMERG9ENCY
MANAGEMENT OFFICIALS ARE AWARE OF THIS INFORMATION.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE MEDIA OUTLET FOR
ANY SEVERE WEATHER WATCHES OR WARNINGS.
