SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
502 AM EST SAT FEB 22 2003

...SEVERE WEATHER AND HEAVY RAINFALL EXPECTED ACROSS THE AREA
TODAY...

AN AREA OF LOW PRESSURE WILL MOVE ACROSS THE TENNESSEE VALLEY
THROUGHOUT THE DAY. THIS WILL ALLOW A WARM FRONT TO LIFT NORTHWARD
ACROSS THE WESTERN CAROLINAS AND NORTHEAST GEORGIA THIS MORNING
THROUGH THE EARLY AFTERNOON. WARM...MOIST...AND UNSTABLE AIR WILL
MOVE IN BEHIND THE WARM FRONT...AND CREATE A FAVORABLE ENVIRONMENT
FOR THE DEVELOPMENT OF THUNDERSTORMS. A LARGE AREA OF RAIN WITH
EMBEDDED THUNDERSTORMS WILL MOVE ACROSS THE AREA THIS MORNING...AND
INTO THE EARLY AFTERNOON. A FEW OF THESE STORMS WILL LIKELY BECOME
SEVERE...WITH THE MAIN THREAT BEING IN THE FORM OF DAMAGING STRAIGHT
LINE WINDS. ISOLATED WEAK TORNADOES WILL ALSO BE POSSIBLE...
ESPECIALLY ALONG THE NORTHWARD MOVING WARM FRONT.

AS A COLD FRONT MOVES TOWARD THE AREA LATER THIS AFTERNOON INTO THIS
EVENING...ANOTHER ROUND OF THUNDERSTORMS WILL BE POSSIBLE. THESE
STORMS COULD ALSO BE SEVERE...WITH A CONTINUED THREAT OF DAMAGING
WINDS. HOWEVER...IT IS POSSIBLE THAT THE ATMOSPHERE WILL BECOME MORE
UNSTABLE THIS AFTERNOON...WHICH WOULD ALLOW FOR THE DEVELOPMENT OF
STRONGER STORMS PRODUCING LARGE HAIL AND ISOLATED TORNADOES.

ALTHOUGH SEVERE WEATHER WILL BE POSSIBLE ACROSS THE ENTIRE AREA
TODAY...IT APPEARS THAT THE GREATEST THREAT FOR SEVERE THUNDERSTORMS
WILL BE IN AREAS SOUTH OF I-85. ALTHOUGH THUNDERSTORMS ARE NOT
EXPECTED TO BE AS INTENSE OVER THE MOUNTAINS...WINDS ALOFT TODAY
ARE EXPECTED TO BE VERY STRONG...AND EVEN WEAK STORMS MAY BE CAPABLE
OF BRINGING SOME OF THESE STRONG WINDS INTO THE VALLEYS...RESULTING
IN DAMAGE TO TREES AND POWER LINES.

IN ADDITION TO SEVERE WEATHER...HEAVY RAINFALL WILL ACCOMPANY SOME
OF THE THUNDERSTORMS. THIS COULD PRODUCE ISOLATED FLOODING ALONG
SMALL CREEKS AND STREAMS...AS WELL AS IN URBAN AND POOR DRAINAGE
AREAS.

STAY TUNED TO NOAA WEATHER RADIO OR THE MEDIA FOR THE LATEST
INFORMATION ON THIS SEVERE WEATHER SITUATION...INCLUDING POSSIBLE
WATCHES AND WARNINGS.
