SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
954 PM EDT WED AUG 9 2000

...SLIGHT CHANCE OF SEVERE THUNDERSTORMS OVERNIGHT IN THE NORTHERN
MOUNTAINS...NORTHERN FOOTHILLS AND NORTHWEST PIEDMONT OF NORTH
CAROLINA...

WEDNESDAY EVENING...A LARGE AREA OF SHOWERS AND THUNDERSTORMS OVER
THE CENTRAL APPALACHIANS...EXTENDING WESTWARD TO THE OHIO VALLEY...
WAS RACING SOUTHWARD...TOWARD THE WESTERN CAROLINAS...AT BETWEEN 55
AND 60 MPH. IF THE AREA WERE TO CONTINUE MOVING AT THIS PACE...THE
LEADING EDGE OF A LINE OF STRONG...TO SEVERE... THUNDERSTORMS WOULD
BE IN THE VICINITY OF THE NORTHERN MOUNTAINS OF NORTH CAROLINA BY
MIDNIGHT. BECAUSE OF THE RAPID MOVEMENT OF THIS AREA...THE
STORM PREDICTION CENTER HAS UPGRADED THE NORTHERN MOUNTAINS...AND
THE NORTHERN FOOTHILLS AND EXTREME NORTHWEST PIEDMONT OF NORTH
CAROLINA...TO A SLIGHT RISK FOR SEVERE WEATHER OVERNIGHT. TOWNS
INCLUDED IN THE SLIGHT RISK AREA INCLUDE BURNSVILLE...NEWLAND...
LENOIR... TAYLORSVILLE...AND MOCKSVILLE.

THE AREA OF CONVECTION IS EXPECTED TO WEAKEN AS IT ENCOUNTERS
SLIGHTLY MORE STABLE AIR OVER OUR REGION...BUT THE RAPID MOVEMENT OF
THE LEADING LINE OF STORMS WILL CREATE FAVORABLE CONDITIONS FOR
DAMAGING STRAIGHT LINE WINDS AND LARGE HAIL. BECAUSE OF THE MOIST
AIRMASS CURRENTLY IN PLACE OVER THE CAROLINAS AND GEORGIA...VERY
HEAVY RAIN WILL ALSO ACCOMPANY ANY THUNDERSTORMS.

THE SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MARCH SOUTHWARD
THROUGH THE PREDAWN...WEAKENING AND EVENTUALLY BREAKING UP.
STILL...WIND GUSTS TO 40 MPH COULD BE EXPERIENCED AS FAR SOUTH AS
ASHEVILLE...HENDERSONVILLE...GLASSY MOUNTAIN...CLAYTON...AND
LINCOLNTON.
