AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
648 PM EDT FRI SEP 2 2011

.SYNOPSIS...
A RIDGE OF WEAK HIGH PRESSURE WILL REMAIN ENTRENCHED ACROSS THE
SOUTHEAST AND DOMINATE OUR WEATHER PATTERN THROUGH SUNDAY. A COLD
FRONT WILL THEN MOVE OVER THE CAROLINAS BY LABOR DAY AND STALL OUT
THROUGH THE MIDDLE OF NEXT WEEK.  MEANWHILE...A TROPICAL DEPRESSION
WILL APPROACH THE GULF COAST...AND SPREAD MOISTURE NORTH ACROSS THE
AREA FROM THE LATE WEEKEND THROUGH THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
ISOLATED TO WIDELY SCATTERED CONVECTION WILL CONTINUE TO DEVELOP
OVER THE HIGHER TERRAIN OF THE WESTERN CAROLINAS AND VIRGINIA THIS
AFTERNOON...AND EVENTUALLY MOVE INTO/DEVELOP OVER THE PIEDMONT. IT
WILL BE INTERESTING TO SEE WHAT HAPPENS AS SOUTHERN NC MTN
CONVECTION MOVES INTO THE UPSTATE LATER THIS AFTERNOON...AS
INSTABILITY DROPS OFF QUICKLY SOUTH OF THE SOUTHERN ESCARPMENT.
SLIGHT CHANCE POPS HAVE NEVERTHELESS BEEN PULLED A LITTLE SOUTH TO
THE I-85 CORRIDOR. CONVECTION WILL BE MOST VIGOROUS OVER THE NC
PIEDMONT LATER THIS AFTERNOON AND EARLY EVENING...AS ANYTHING
DEVELOPING OVER OR MOVING INTO THAT AREA WILL HAVE STRONG
INSTABILITY TO WORK WITH. ALTHOUGH FREEZING LEVELS ARE QUITE HIGH
OVER THE REGION...DOWNDRAFT CAPE IS ALSO VERY HIGH...ESP OVER THE NC
PIEDMONT. THERE SHOULD BE AN ENHANCED RISK FOR ISOLATED MICROBURSTS
WITH THE STORMS THIS AFTERNOON/EARLY EVENING. ANY ONGOING CONVECTION
SHOULD WEAKEN THROUGH LATE EVENING...AFTER WHICH A WARM NIGHT IS
EXPECTED...OWING TO HIGHER DEWPOINTS AND CONVECTIVE DEBRIS. MIN
TEMPS SHOULD AVERAGE ABOUT A CATEGORY ABOVE NORMAL.

FOR SATURDAY...THE UPPER HIGH WILL BE WEAKENING OVER THE AREA...AS
IT WILL BE /UNDER ASSAULT/ FROM ALL SIDES...FROM THE NORTHWEST WITH
APPROACH OF A MAJOR UPPER TROUGH...FROM THE SOUTHWEST DUE TO THE
CIRCULATION AROUND T.S. LEE...AND TO THE EAST DUE TO WEAKENING UPPER
LOW. WITH RESULTANT LOWERING THICKNESSES AND DEVELOPING EASTERLY
FLOW...MAXES SHOULD BE ABOUT 5 DEGREES COOLER THAN TODAY. THERE WILL
ALSO BE PERSISTING CHANCES FOR DIURNAL CONVECTION...ESP ALONG THE
EASTERN/SOUTHERN ESCARPMENT...WHERE THE USUAL TERRAIN EFFECTS WILL
BE AIDED BY WEAK UPSLOPE FLOW.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 230 PM FRIDAY...UPPER RIDGE CONTINUES TO WEAKEN SUN AS A
SHORTWAVE APPROACHES FROM THE NW. THE SFC PRES GRADIENT BETWEEN TS
LEE IN THE W GULF...AND HIGH PRES OFF THE E COAST WILL PUT THE CWA
IN LGT S FLOW SUN. AS THE UPPER TROF AND ASSOC SFC COLD FRONT MOVE
IN FROM THE NW...AND WITH MOISTURE SURGING N AHEAD OF THE SYSTEM...
EXPECT CHC POPS OVER THE MTNS EARLY IN THE DAY...SPREADING ACROSS
THE CWA IN THE AFTN. WITH LOWER HEIGHTS AND INCRSNG CLOUDS...LOWS
WILL BE ABOVE AVG WITH HIGHS NEAR AVG SUN AFTN. AS THE FRONT MOVES
INTO THE MTNS SUN NIGHT...INCRSNG S WINDS WILL BRING DEEPER MOISTURE
OVER THE AREA. THE UPPER TROF SLOWS DOWN MON WITH A WEAK SHORTWAVE
RIDGE MOVG OVER THE CWA FROM THE SW BUT THE SFC FRONT STALLS OVER
THE AREA. COMBINED WITH STRONG LL UPGLIDE/UPSLOPE AND DEEP MOISTURE
HAVE LIKELY POPS WITH PERIODS OF MDT RAIN EXPECTED. HIGHS WILL BE
BELOW AVG MON.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 230 PM FRIDAY...MODELS ARE COMING INTO BETTER AGREEMENT FOR
THE MON NIGHT-FRI TIME FRAME WITH THE COLD FRONT STALLED OVER THE
AREA TUE WHILE MOISTURE FROM TD13 CONTINUES TO SURGE UP FROM THE
GULF ON INCREASING S FLOW. IT APPEARS THAT MDT TO HEAVY RAIN WILL BE
THE MAIN CONCERN...ESPECIALLY ALONG THE BLUE RIDGE ESCARPMENT WITH
PERSISTENT ISENTROPIC LIFT AND UPSLOPE FLOW. ON WED MODELS SHOW THE
UPPER TROF MOVG E WITH THE SFC LOW ASSOC WITH TS LEE MOVG SLOWLY N
TOWARD CNTRL TN AS IT FILLS. THIS WILL KEEP THE AREA IN DEEP...
MOIST S FLOW SO KEPT LIKELY POPS OVER THE MTNS/FOOTHILLS THRU THE
DAY. DETAILS ARE UNCERTAIN BUT GFS IS FASTER BRINGING DRYER AIR IN
BEHIND THE SYSTEM. BOTH MODELS AGREE ON DEEP DRYING WED NIGHT-THU
AND HELD ON TO CHC POPS THU WITH A SLIGHT CHC ON FRI. TEMPS WILL BE
BELOW AVG THRU FRI.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
AT KCLT...A ROUND OF GUSTY TSTMS LOOKS PROBABLE EARLY THIS EVENING.
LATER TONIGHT...LINGERING DEBRIS CLOUDS SHOULD DIMINISH AND SFC
WINDS...ALTHOUGH REMAINING LIGHT WILL BECOMING NE. THERE WILL LIKELY
BE MOISTENING OF THE BLYR TOWARD DAYBREAK BUT IT IS NOT CONCLUSIVE
THAT CIGS NEAR 1K FEET WILL REACH KCLT...BUT WILL CERTAINLY BEAR
WATCHING AS THE NIGHT WEARS ON. WILL PLAN ON KEEPING FCST VSBY NOT
WORSE THAN MVFR PENDING HOW MUCH RAIN FALLS THIS EVENING. ON
SATURDAY...WITHIN THE EASTERLY FLOW...FORCING FOR DEEP CONVECTION
IS SHAPING UP TO BE GREATEST CLOSER TO THE MTNS...SO THERE IS NO
PLAN TO ADD ANY CB MENTION AT THIS TIME.

ELSEWHERE...SAVE FOR A NEAR TERM TSTM PROBABILITY AT KHKY...DEEP
CONVECTIVE PROBABILITIES LATER THIS EVENING ACRS THE UPSTATE
TERMINALS AND KAVL LOOK SMALL ENUF FOR FORGO ANY CB MENTION. WILL
PROBABLY CONTINUE TO LIMIT PRE-DAWN UPSTATE VSBY REDUCTIONS TO JUST
KAND AND A PERIOD OF IFR BR AT KAVL. WITH SCATTERED AFTERNOON MTN
TSTMS EXPECTED ON SATURDAY...WILL INTRODUCE CB AT KAVL.

OUTLOOK...VFR WEATHER EXCEPT OCCASIONAL MORNING VISIBILITY
RESTRICTIONS IN FOG AND HAZE. ON MONDAY...MVFR AND IFR WEATHER IS
POSSIBLE IN SHOWERS AND THUNDERSTORMS AS A COLD FROM ARRIVES FROM
THE NW. THE EARLY PART OF NEXT WEEK MAY SEE EXTENDED PERIODS OF LOW
CLOUDS AND LOW VISIBILITY.
