Area forecast discussion, Jul 29, 10:10 AM EDT, 3 hours 2 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1010 AM EDT SUN JUL 29 2001

VERY MOIST AIR MASS IN PLACE TODAY ACROSS THE ENTIRE FORECAST AREA
WITH PW ON GSO MORNING RAOB AROUND 2.1 INCHES...170 PERCENT OF
NORMAL...AND SURFACE BOUNDARY ANALYZED TO THE NORTH. SATELLITE/KGSP
RADAR SHOWS AREA OF WARM-TOPPED CONVECTION MOVING SLOWLY EAST BUT
REMAINING OVER NC. MAIN CONCERN FOR TODAY IS THE POTENTIAL FOR
FLOODING...AND CURRENT FLASH FLOOD WATCH HAS THE GREATEST THREAT
AREA OUTLINED NICELY. WILL NOT EXPAND AT THIS TIME.

THE CURRENT SET OF ZONES IS IN NEED OF SEVERAL ADJUSTMENTS BASED ON
THE CURRENT LOCATION OF THE PRECIP. THE NC SRN PIEDMONT ZONES WILL
BE BROKEN OUT TO GO WITH A CATEGORICAL POP BASED ON THE LIGHT RAIN
ALREADY MOVING ACROSS THAT AREA. THE SOUTHERNMOST ZONES WILL ALSO BE
BROKEN OUT TO BRING THE PRECIP IN DURING THE LATER PART OF THE
AFTERNOON. TEMPS ARE AT LEAST A CATEGORY OR TWO TOO WARM OWING TO
THE EXTENSIVE CLOUD COVER AND ONGOING PRECIP ACROSS ALL BUT THE
SOUTHERNMOST ZONES...IF THEY GET A FEW BREAKS IN THE CLOUD COVER.

THE RUC INDICATES THAT THE MAIN BAND OF PRECIP WILL SLOWLY SHIFT
SOUTH INTO NORTHERN SOUTH CAROLINA LATE IN THE DAY. IF THAT IS THE
CASE...THEN THE PRECIP CHANCE FOR TONIGHT IS WAY TOO LOW. WILL NOT
UPDATE TONIGHT PERIOD AT THIS TIME...BUT EXPECT TO BUMP POPS UP IN
THE NEXT SET OF ZONES.

.GSP...
GA...NONE.
kNC...FLASH FLOOD WATCH TODAY FOR ZONES NCZ033>034...
NCZ048>055...NCZ058>059.
