SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1210 PM EDT WED JUN 13 2001

...A FEW SEVERE THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON AND THIS
EVENING...

THE ATMOSPHERE WILL BECOME QUITE UNSTABLE THIS AFTERNOON...DUE TO
LINGERING TROPICAL MOISTURE...AS AN OLD AREA OF LOW PRESSURE MOVES
AWAY TO THE EAST. A SMALL BUT STRONG UPPER LEVEL SYSTEM IS EXPECTED
TO MOVE SOUTH ACROSS THE WESTERN CAROLINAS AND NORTHEAST GEORGIA
THROUGH THIS EVENING...WHICH WILL AID THUNDERSTORM DEVELOPMENT.

SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON. SOME
OF THE THUNDERSTORMS MAY GROW STRONG ENOUGH TO PRODUCE SMALL HAIL
AND GUSTY WINDS...AND A FEW OF THE THUNDERSTORMS MAY PRODUCE
DAMAGING WIND GUSTS. ANY THUNDERSTORMS THAT DEVELOP SHOULD PRODUCE
HEAVY RAIN...PERHAPS ENOUGH TO PRODUCE SOME FLOODING PROBLEMS IF
SEVERAL STORMS MOVE ACROSS THE SAME LOCATION. WIDESPREAD SEVERE
WEATHER IS NOT EXPECTED.

THE BEST CHANCE OF SEVERE WEATHER WILL BE OVER THE MOUNTAINS...WITH
THE POSSIBILITY OF A SEVERE STORM OR TWO MOVING OUT OF THE MOUNTAINS
INTO THE FOOTHILLS AND PIEDMONT IN THE LATE AFTERNOON OR EARLY
EVENING.  CONTINUING RAIN AND CLOUDS LATE THIS MORNING OVER PARTS OF
THE PIEDMONT...FROM YORK AND UNION SOUTH CAROLINA...TO SOUTH OF
CHARLOTTE...WILL REDUCE THE THREAT OF SEVERE WEATlHER IN THOSE
LOCATIONS.
