AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
509 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/...
OUTFLOW DRIVE CONVECTION WILL PUSH EAST ACROSS THE PIEDMONT THROUGH
MID EVENING. ADDITIONAL SCATTERED ACTIVITY WILL LIKELY DEVELOP BACK
OVER THE MTNS AS UPPER LEVEL SHORTWAVES AHEAD OF THE MAIN TROUGH
APPROACH. SHEAR REMAINS SOMEWHAT LIMITED...AND INSTABILITY SHOULD
STEADILY WANE THROUGH THE EVENING HOURS TO KEEP THE SEVERE THREAT A
BIT MARGINAL. HOWEVER...FORCING WILL GRADUALLY IMPROVE AND COVERAGE
SHOULD RAMP UP AGAIN FROM THE WEST OVERNIGHT AS A COLD FRONT
APPROACHES. ANY HYDRO PROBLEMS IN THE HEAVIEST SHOWERS SHOULD BE
ISOLATED AS THE STORMS ARE MOVING EAST AROUND 20 KT.
HOWEVER...FLOODING COULD STILL OCCUR IN ANY TRAINING THAT
DEVELOPS.

SUNDAY...ANOTHER 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 /21Z SATURDAY THROUGH THURSDAY/...
AT KCLT...THUNDERSTORM OUTFLOWS SHOULD PRODUCE TSRA AT KCLT BETWEEN

CIGS SHOULD FALL TO MVFR DURING THE TSRA...BUT WITH VFR CLOUDS
LIKELY INTO THE EARLY MORNING HOURS...FOLLOWED BY MVFR AGAIN AFTER

INCREASE THROUGH SUNDAY AS UPPER SUPPORT INCREASES ALONG WITH THE
ARRIVAL OF A SFC COLD FRONT. SE WINDS EARLY IN THE PERIOD WILL
BECOME WESTERLY LATE IN THE PERIOD.

ELSEWHERE...THE INITIAL BAND OF OUTFLOW DRIVEN THUNDERSTORMS WILL
LKELY MOVE EAST OF A KAND TO KGSP TO KHKY LINE BY MID EVENING...BUT
ADDITIONAL THUNDERSTORMS ARE EXPECTED TO FILL IN TO THE WEST LATE
THIS EVENING OVERNIGHT AS UPPER SUPPORT IMPROVES AND A COLD FRONT
ARRIVES FROM THE NW. THE PRECIPITATION AND LOW LEVEL MOISTURE WILL
YIELD IFR TO MVFR CONDITIONS THROUGHOUT OVERNIGHT. PRECIPITATION
CHANCES WILL SLOWLY END FROM SW TO NE THROUGH SUNDAY AFTN...ALONG
WITH RESTRICTIONS. WESTERLY WINDS SHOULD DEVELOP BY LATE MORNING AND
INCREASE THROUGH LATE DAY.

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