905 PM EDT WED AUG 6 2003

KGSP RADAR SHOWS MOST OF THE REMAINING CONVECTION CONFINED TO THE NC
FOOTHILLS AND THE SOUTHERN PART OF THE CLT METRO AREA. LAPS ANALYSIS
SHOWS MOST OF THE REMAINING SURFACE BASED INSTABILITY LIMITED TO THE
NC PIEDMONT...WHICH STANDS THE BEST CHANCE OF ADDITIONAL PRECIP FOR
THE REST OF THE EVENING. WATER VAPOR IMAGERY SHOWS VORT AXIS MOVING
IN FROM N GA. AS THIS FEATURE SWINGS THROUGH THE REGION OVERNIGHT...
IT COULD TRIGGER ADDITIONAL CONVECTION AT ANY TIME. WILL NOT LOWER
POP BELOW CHANCE RANGE FOR THAT REASON...BUT WILL ADJUST POPS TO
MATCH ONGOING CONVECTION. AS FOR TEMPS...AREAS OF THE LOWER SC
PIEDMONT ARE ALREADY AT FCST LOWS OWING TO COOL POOL IN THE WAKE OF
EARLIER CONVECTION. WILL TWEAK TEMPS DOWN THERE BY A DEGREE...BUT
WILL LEAVE TEMPS ALONE ELSEWHERE.

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