AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
247 PM EDT THU AUG 11 2011

.SYNOPSIS...
HIGH PRESSURE WILL MOVE FROM THE OHIO VALLEY TODAY TO THE EAST COAST
ON FRIDAY. A COLD FRONT WILL THEN APPROACH THE AREA FROM THE
NORTHWEST LATE SATURDAY AND MOVE OVER THE CAROLINAS EARLY SUNDAY
BRINGING SHOWERS AND THUNDERSTORMS.

&&

.NEAR TERM /THROUGH FRIDAY/...
EXPECT THE CONVECTION DEVELOPING ALONG THE BLUE RIDGE TO MOVE SOUTH
AND EAST INTO THE FOOTHILLS AND PIEDMONT THRU THE AFTERNOON.
ADDITIONAL CONVECTION WILL DEVELOP OVER THE SRN UPSTATE NEAR A WEAK
LOW PRESSURE AND SFC BOUNDARY. THIS SHOULD LEAD TO AT LEAST SCT
COVERAGE ACROSS MOST OF THE CWFA UNTIL EVENING. SOME OF THE STORMS
COULD BE SEVERE GIVEN THE MODERATE SHEAR AND INSTABILITY ACROSS THE
AREA.

OVERNIGHT...EXPECT THE CONVECTION TO DISSIPATE BUT SHOWERS COULD
LINGER THRU THE NIGHT...ESP IN NC...DUE TO CONTINUED LOW LEVEL SELY
FLOW AND DECENT LOW LEVEL MOISTURE. CLOUDS SHOULD LINGER AS WELL
HELPING TO KEEP LOWS AROUND NORMAL.

WEAK SHORT WAVE ENERGY MOVES ACROSS THE AREA FRIDAY IN THE LINGERING
UPPER TROF. AT THE SFC...AN INVERTED TROF DEVELOPS OVER THE AREA
BETWEEN HIGH PRESSURE PASSING BY TO THE NORTH AND A WEAK LOW
PRESSURE CENTER OVER SRN GA. LOW LEVEL FLOW WILL REMAIN SELY WITH
CONTINUED LOW LEVEL MOISTURE. EXPECT CONVECTION TO DEVELOP ONCE
AGAIN AND COULD BE EVEN MORE WIDESPREAD THAN THU. HAVE KEPT POP AT
SCT COVERAGE FOR NOW...BUT LIKELY MAY BE NEEDED OUTSIDE OF THE MTNS.
WITH THE LINGERING CLOUDS AND LOWER THICKNESSES...HIGH TEMPS WILL BE
RIGHT AROUND NORMAL.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AS OF 130 PM THURSDAY...THE SHORT TERM FCST PICKS UP AT 00Z ON
SATURDAY WITH THE BEGINNING OF A MARKEDLY MORE ACTIVE PERIOD.
VARIOUS LOBES OF SHORTWAVE ENERGY IN THE MID/UPPER LVLS PROPAGATE
TOWARDS THE FCST AREA AS THE UPPER LVL TROF DIGS DOWN OVER THE UPPER
MISS RIVER VALLEY AND ARRIVES AT OUR DOORSTEP BY 00Z SUNDAY. ON
SATURDAY...THE SFC HIGH SLIDES OFF THE ATLANTIC SEABOARD CAUSING OUR
LOW LVL WINDS TO CONTINUE TO VEER AROUND TO SOUTHERLY. LOW AND MID
LVL MOISTURE WILL QUICKLY RAMP UP IN THE AFTERNOON/EVENING WITH PWAT
VALUES INCREASING ABOVE CLIMATOLOGY. LATEST MODEL SOUNDINGS GENERATE
SOME HEALTHY INSTABILITY OVER MOST OF THE CWFA...HOWEVER BEST
FORCING AND MOISTURE INFLUX IS EXPECTED SUNDAY MORNING DURING THE
MINIMUM INSOLATION PERIOD. REGARDLESS...BY SAT EVENING I RAMP POPS
UP TO LIKELY OVER MOST OF THE NC MTS AND HIGH END SOLID CHANCE
ELSEWHERE. TEMPS SHOULD BE RIGHT AROUND CLIMO WITH HIGHS AROUND 90
OVER THE LOWER ELEVATIONS AND LOW TO MID 80S FOR THE MTS. ON
SUNDAY...THE FRONTAL BOUNDARY WILL MOVE OVER THE FCST AREA EARLY
WITH COOLER AND DRIER NWLY FLOW IN ITS WAKE. I EXPECT WIDESPREAD
SHOWERS AND TS WITH SOME ORGANIZED SVR POTENTIAL...HOWEVER THE BEST
DYNAMICS DO NOT COINCIDE WITH THE BEST HEATING...SO INSTABILITY WILL
BE SOMEWHAT MINIMAL DURING THE FROPA. THINGS WILL DRY OUT SUNDAY
EVENING AS THE FRONT MOVES SE OF THE CWA AND I LOWER POPS TO CHANCE
OVER THE MTS FOR ANY LINGERING NW FLOW MOISTURE. TEMPS WILL LIKELY
BE A BIT BELOW CLIMO WITH THE WIDESPREAD CLOUD COVER AND PRECIP.

&&

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
AT 2 PM EDT THURSDAY...AN UPPER TROUGH WILL REMAIN ALONG THE EAST
COAST FROM MONDAY THROUGH THURSDAY. A COLD FRONT WILL DEPART OUR
AREA TO THE SOUTHEAST ON SUNDAY NIGHT...THEN RELATIVELY COOL AND DRY
HIGH PRESSURE WILL BUILD OVER THE AREA FROM THE NORTHEAST THROUGH
THURSDAY. POPS WILL BE MINIMAL...AND MAINLY BASED IN THE MOUNTAINS
FOR OROGRAPHIC EFFECTS. TEMPERATURES WILL RESEMBLE LATE SUMMER OF
EARLY AUTUMN.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
AT KCLT AND ELSEWHERE...LINE OF TSRA FORMING ALONG THE BLUE RIDGE
WILL SPREAD EAST AND SOUTH THRU THE AFTERNOON. HAVE INCLUDED CB
EVERY SITE WITH TEMPO TS AT KHKY WHERE TSRA IS NEARBY. WILL AMD
OTHER STIES AS NEEDED. OTHERWISE...EXPECT VFR CIGS TO DEVELOP THIS
AFTERNOON AND CONTINUE OVERNIGHT AS SELY FLOW ACTS ON LINGERING LOW
LEVEL MOISTURE. EVEN THE MORE BULLISH NAM KEEPS CIGS AT TAF SITES
VFR...SO HAVE GONE THAT WAY AS WELL. BEST CHC FOR ANY FOG IS AT
KAVL. DID NOT MENTION ANY SHRA BUT THEY COULD LINGER OVERNIGHT AT
THE NC SITES AS WELL. EXPECT AN EVEN BETTER DAY FOR CONVECTION FRI
BUT TOO EARLY TO INCLUDE IN TAFS ATTM. KEPT VFR CIGS THRU THE
PERIOD. WINDS ARE TRICKY WITH WEAK LOW PRESSURE AND LEE TROF IN
PLACE. HAVE TRENDED TOWARD A MDL BLEND WITH E TO SE WIND BECOMING NE
OVERNIGHT. KAVL THE EXCEPTION WHERE N WIND CONTINUES.

OUTLOOK...EVEN BETTER CONVECTION CHANCES SATURDAY AND SUNDAY. A COLD
FRONT SHOULD BRING MUCH DRIER WEATHER MON AND TUE.
