POSSIBLE...

TYPICAL MID-JULY HEAT AND HUMIDITY WILL RESULT IN THE ATMOSPHERE

TERRAIN...INTO THE FOOTHILLS AND PIEDMONT. IN ADDITION...A TROUGH OF
LOW PRESSURE EAST OF THE MOUNTAINS IS EXPECTED TO PROVIDE A FOCUS
FOR THE DEVELOPMENT OF ADDITIONAL SHOWERS AND THUNDERSTORMS. SOME OF
THESE STORMS WILL ALSO BE CAPABLE OF PRODUCING LARGE HAIL...DAMAGING
WIND GUSTS...AND LOCALIZED FLASH FLOODING. THUNDERSTORMS WILL BEGIN
TO WEAKEN SHORTLY AFTER SUNSET...AND SHOULD DISSIPATE BY MIDNIGHT.

SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
330 PM EDT WED JUL 16 2003

...ISOLATED FLOODING AND A FEW SEVERE THUNDERSTORMS POSSIBLE THIS
EVENING...

SCATTERED THUNDERSTORMS WILL CONTINUE TO DEVELOP ACROSS THE WESTERN
CAROLINAS AND NORTHEAST GEORGIA THROUGH SUNSET. ANY THUNDERSTORMS
THAT DEVELOP WILL DRIFT SLOWLY SOUTHEAST...PRODUCING HEAVY RAINFALL
OF 1 TO 2 INCHES OVER AFFECTED AREAS. THIS RAINFALL MAY BE
SUFFICIENT TO PRODUCE LOCALIZED FLOODING IN POOR DRAINAGE LOCATIONS.
IF THUNDERSTORMS DEVELOP REPEATEDLY IN THE SAME GENERAL
AREA...STREAMS AND CREEKS WILL ALSO EXPERIENCE VERY RAPID RISES AND
SOME COULD APPROACH BANKFULL.

THE GREATEST THREAT OF EXCESSIVE RAINFALL THIS EVENING WILL BE OVER
THE NORTH CAROLINA FOOTHILLS...ESPECIALLY JUST EAST OF THE BLUE
RIDGE. ANY LOCATION ACROSS THE REGION...HOWEVER...WILL BE
SUSCEPTIBLE TO TORRENTIAL RAINFALL IF A THUNDERSTORM DEVELOPS.

IN ADDITION TO THE HEAVY RAIN...ANY OF THESE STRONG THUNDERSTORMS
WILL ALSO HAVE THE POTENTIAL TO PRODUCE SMALL HAIL AND WIND GUSTS TO
35 MPH. A FEW THUNDERSTORMS COULD BECOME SEVERE...GENERATING HAIL
THE SIZE OF PENNIES OR NICKELS AND WIND GUSTS TO 60 MPH. THE
THUNDERSTORMS ARE EXPECTED TO DISSIPATE BY MIDNIGHT.

SPOTTER GROUPS SHOULD BE PREPARED TO RELAY REPORTS OF FLOODING...
WIND...OR HAIL TO THE NATIONAL WEATHER SERVICE. DISPATCHERS SHOULD
