AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
300 PM EDT WED JUL 24 2002

CONVECTION HAS ONCE AGAIN DEVELOPED ACROSS A GOOD PORTION OF THE CWA
THIS AFTERNOON. EXPECT BEST COVERAGE THROUGHOUT THE AFTERNOON AND
EVENING TO OCCUR ACROSS THE MOUNTAINS...AND ALONG AND NEAR THE
SURFACE FRONT THAT CONTINUES TO MAKE SLOW PROGRESS THROUGH NORTHERN
NC. MODEL CONSENSUS IS TO HANG THIS BOUNDARY UP ACROSS NORTHERN
PORTIONS OF OUR CWA THROUGH EARLY FRIDAY. ALTHOUGH MID LEVEL SHEAR
AXIS AND ASSOCIATED COOL POOL THAT HAS SUPPORTED CONVECTION OVER THE
PAST COUPLE OF DAYS WILL CONTINUE TO WEAKEN...VERY MOIST ATMOSPHERE
COMBINED WITH FRONT WARRANTS HIGH CHANCE TO LIKELY POPS ACROSS THE
AREA THROUGH THURSDAY NIGHT.

HEIGHTS BEGIN FALLING ACROSS THE EASTERN U.S. THURSDAY NIGHT INTO
FRIDAY...AS SERIES OF SW TROUGHS SWING ACROSS THE MIDWEST INTO THE
NORTHEAST. THIS WILL ALLOW WEAKENING FRONT AND DEEPER MOISTURE TO
PUSH EAST OF THE AREA DURING THE DAY FRIDAY...SUPPORTING LOWER POPS.
WILL RETAIN LOW CHANCE POP FOR SATURDAY TO COVER POSSIBILITY FOR
DIURNAL CONVECTION...ALTHOUGH SUSPECT THAT THIS WILL HAVE TO BE
LOWERED IN LATER PACKAGES.

MID LEVEL RIDGE BEGINS TO BUILD OVER THE SOUTHEAST DURING THE DAY
SUNDAY AND REMAINS IN PLACE THROUGH THE EARLY PART OF THE WORK
WEEK...SUPPORTING VERY WARM TEMPS AND MINIMAL PRECIP CHANCES.
ANOTHER FRONT WORKS ITS WAY TOWARD THE AREA BY WEDNESDAY...BUT HAVE
OPTED TO LEAVE POPS OUT OF THE FORECAST FOR NOW.

.GSP...
GA...NONE.
NC...NONE.
SC...NONE.
