SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1117 AM EDT MON APR 21 2003

..A FEW SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON...

SCATTERED THUNDERSTORMS HAVE DEVELOPED ACROSS THE WESTERN CAROLINAS
AND EXTREME NORTHEAST GEORGIA TODAY AHEAD OF AN APPROACHING COLD
FRONT. THERE IS A CHANCE THAT A FEW OF THE THUNDERSTORMS COULD BE
SEVERE THIS AFTERNOON. A LIMITING FACTOR WILL BE THE AMOUNT OF
INSTABILITY GIVEN THE PERSISTENT LOW CLOUDS CAUSING LOWER
TEMPERATURES THAN PREVIOUSLY EXPECTED.

THE BEST CHANCE FOR SEVERE THUNDERSTORMS WILL BE ACROSS THE
NORTHWEST PIEDMONT OF NORTH CAROLINA...OR ROUGHLY NORTH OF A LINE
FROM SALISBURY TO STATESVILLE AND TAYLORSVILLE. HOWEVER...A FEW OF
THE THUNDERSTORMS THAT MOVE ACROSS THE REST OF THE WESTERN CAROLINAS
AND EXTREME NORTHEAST GEORGIA COULD PRODUCE DAMAGING WIND GUSTS AND
LARGE HAIL.

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