AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
244 PM EDT SAT AUG 13 2011

.SYNOPSIS...
A COLD FRONT WILL APPROACH THE AREA FROM THE NORTHWEST AND MOVE
ACROSS THE WESTERN CAROLINAS LATE SUNDAY INTO EARLY MONDAY. HIGH
PRESSURE WILL GRADUALLY BUILD INTO THE REGION EARLY NEXT WEEK...
BEFORE WEAKENING BY MID-WEEK. ANOTHER COLD FRONT WILL LIKELY
APPROACH THE AREA BY THE END OF NEXT WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
CONVECTION HAS FORMED OVER THE MTNS AND ALONG A WEAK BOUNDARY JUST
SOUTH OF THE CWFA. EXPECT SCT STORMS TO MOVE OFF THE MTNS AND ACROSS
THE CWFA THRU THE AFTERNOON. EFFECTIVE SHEAR IS NOT AS STRONG TODAY
BUT MODERATE INSTABILITY AND DCAPE SHOULD HELP A FEW OF THE STORMS
TO PRODUCE SEVERE DOWNBURST WINDS. ISOLATED FLOODING CANNOT BE RULED
OUT GIVEN HIGH PW VALUES. NUMEROUS SHOWERS AND SCT STORMS ARE
EXPECTED TO MOVE IN THIS EVENING AND OVERNIGHT AS AN UPPER TROF
BRINGS FORCING AND UPPER DIVERGENCE INTO THE AREA. SEVERE CHANCE NOT
VERY HIGH OVERNIGHT...BUT FLOOD THREAT COULD BE GREATER GIVEN THE
CONTINUED HIGH PW VALUES AND BETTER SYNOPTIC FORCING. LOWS ABOVE
NORMAL.

SUNDAY...SHORT WAVE ROUNDS THE LONG WAVE TROF AND MOVES INTO THE
AREA. DEEP MOISTURE MOVES EAST DURING THE DAY TAKING THE CHC OF
WIDESPREAD CONVECTION WITH IT. HOWEVER...ENUF LOW LEVEL MOISTURE
WILL REMAIN FOR SCT CONVECTION TO DEVELOP BEHIND THE DEEP MOISTURE
ACROSS NC. DRIER AIR AND WLY FLOW SHOULD HELP KEEP CONVECTION TO A
MINIMUM OVER THE WRN UPSTATE AND NE GA DURING THE AFTERNOON. HIGHS
WILL BE TRICKY WITH WITH CLOUDS AND PRECIP EARLY BUT CLEARING SKIES
AT LEAST ACROSS THE SWRN CWFA FOR THE AFTERNOON. HAVE TRENDED TOWARD
THE COOLER MET WHICH IS A LITTLE BELOW NORMAL FOR SC BUT NEAR NORMAL
FOR THE UPSTATE AND NE GA.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
AT 2 PM EDT SATURDAY...AN UPPER LEVEL TROUGH WILL RESIDE ALONG THE
EASTERN SEABOARD FORM SUNDAY NIGHT THROUGH TUESDAY...WITH A WELL
DEFINED SHORTWAVE MOVING THROUGH ITS BASE ON MONDAY. A COLD FRONT TO
OUR EAST WILL SLOWLY DEPART SUNDAY NIGHT...WHILE NW FLOW UPSLOPE
SHOWERS PERSIST IN THE NC MOUNTAINS BORDERING TN. THESE SHOWERS WILL
ABATE ON MONDAY AS DRY HIGH PRESSURE BUILDS EAST ACROSS THE
APPALACHIANS. TEMPERATURES WILL RUN ONE CATEGORY OR SO BELOW NORMAL.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AT 2 PM EDT SATURDAY...A MEAN UPPER TROUGH WILL REMAIN ALONG THE
EAST COAST FORM TUESDAY NIGHT THROUGH SATURDAY. SOME WEAKENING OF
THE TROUGH IS EXPECTED WEDNESDAY AS SHORTWAVE RIDING MOVES THROUGH
BEHIND A DEPARTING SYSTEM...BUT MAJOR REAMPLIFICATION WILL TAKE
PLACE LATE IN THE WEEK AN UPPER LOW REACHES EASTERN CANADA...AND
SHORTWAVES DIVE SOUTHEAST INTO THE APPALACHIANS. RELATIVELY COOL
HIGH PRESSURE WILL REMAIN OVER THE CAROLINAS AND GA FORM WEDNESDAY
INTO FRIDAY. THIS AIR MASS WILL START OUT ABNORMALLY DRY FOR THIS
TIME OF YEAR...BUT WILL GRADUALLY MODIFY AS LOW LEVEL FLOW VEERS
FROM NE TO SE...AND MOISTURE IS LIFTED UPSLOPE FROM THE ATLANTIC. A
SLOW MOVING AND WEAKENING COLD FRONT APPROACHES FROM THE NW LATE
FRIDAY...AND FORECAST CONFIDENCE DECREASES AS THE FATE OF THIS
BOUNDARY IS UNCLEAR. POPS WILL START OUT QUITE LOW...INCREASING IN
STEP WITH MOISTURE LATE IN THE WEEK...ESPECIALLY ALONG THE UPSLOPE
FLOW FAVORED BLUE RIDGE. TEMPERATURES WILL RUN SLIGHTLY BELOW NORMAL
UNDER THE UPPER TROUGH.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
AT KCLT AND ELSEWHERE...CLOUD BASES ARE GENERALLY LOW VFR AND SHOULD
REMAIN THAT WAY UNLESS A CONVECTIVE CELL MOVES OVER THE AIRFIELD.
HAVE LOW VFR CIGS AND CB NOW OR BY 20Z GIVEN CELL MOVEMENT. CELL
MOVEMENT WILL BE THE PRIME DETERMINANT FOR RESTRICTIONS THIS
AFTERNOON. EXPECT WIDESPREAD SHOWERS AND SCT STORMS OVERNIGHT AS A
FRONT MOVES INTO THE AREA AND MVFR TO IFR CONDS. PRECIP CHC ENDS
FROM SW TO NE THRU THE DAY SUN...AS DO RESTRICTIONS. STILL TOO EARLY
TO TELL WHAT AREAS WILL NEED CB. WINDS WILL BECOME SLY THROUGH THE
AFTERNOON THEN LIGHT OVERNIGHT. WLY WIND EXPECTED TO DEVELOP BY MID
MORNING SUNDAY.

OUTLOOK...TSTM CHANCES DIMINISH SUNDAY NIGHT AS THE COLD FRONT MOVES
EAST. EXPECT DRIER WEATHER MON-WED...INCREASING CHC CONVECTION THU
AS ANOTHER SYSTEM APPROACHES FROM THE W.
