SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1150 AM EST SAT MAR 9 2002

...SEVERE THUNDERSTORMS POSSIBLE FROM LATE AFTERNOON THROUGH EVENING
ACROSS THE WESTERN CAROLINAS AND NORTHEAST GEORGIA...

A COLD FRONT WILL MOVE RAPIDLY EAST ACROSS THE SOUTHERN APPALACHIANS
THIS EVENING. THIS FRONT WILL INTERACT WITH THE WARM AND MOIST
AIRMASS IN PLACE ACROSS THE SOUTHEAST TO MAINTAIN A PERSISTENT LINE
OF SHOWERS AND THUNDERSTORMS. SHOWERS AND THUNDERSTORMS HAVE ALREADY
DEVELOPED AHEAD OF THE FRONT IN WESTERN TENNESSEE...AND THIS LINE
SHOULD REACH THE NORTH CAROLINA MOUNTAINS BY LATE AFTERNOON OR EARLY
EVENING.

STRONG WINDS ALOFT IN THE ATMOSPHERE TODAY WILL CREATE THE POTENTIAL
FOR DAMAGING WIND GUSTS TO DEVELOP. WIND GUSTS TO NEAR 60 MPH WILL
BE POSSIBLE WITH THE LINE OF THUNDERSTORMS. DIME SIZED HAIL MAY ALSO
ACCOMPANY THE PASSAGE OF THE LINE. THE THUNDERSTORMS SHOULD AFFECT
THE MOUNTAINS OF THE WESTERN CAROLINAS AND NORTHEAST GEORGIA BETWEEN
4 AND 8 PM THIS EVENING...WHILE ADJACENT FOOTHILL AND PIEDMONT
SECTIONS WILL BE AFFECTED MAINLY FROM 8 PM TO MIDNIGHT.

SPOTTER GROUPS SHOULD BE PREPARED TO ACTIVATE QUICKLY LATE THIS
AFTERNOON AND THIS EVENING SHOULD SEVERE WEATHER DEVELOP.
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

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

THUNDERSTORMS WILL AFFECT THE MOUNTAINS OF THE WESTERN CAROLINAS AND
NORTHEAST GEORGIA THROUGH ABOUT 7 PM THIS EVENING...AND THEN
PIEDMONT SECTIONS THROUGH MIDNIGHT.
