AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
659 PM EDT THU SEP 1 2011

.SYNOPSIS...
A RIDGE OF HIGH PRESSURE WILL REMAIN ENTRENCHED ACROSS THE SOUTHEAST
AND DOMINATE OUR WEATHER THROUGH SUNDAY. A COLD FRONT IS EXPECTED TO
MOVE IN BY LABOR DAY AND STALL NEAR THE AREA THROUGH THE MIDDLE OF
NEXT WEEK.

&&

.NEAR TERM /THROUGH FRIDAY/...
TWEAKED LATE DAY POP TO REFLECT DEEP CONVECTIVE CVRG...LOW TO SLIGHT
CHANCES ALONG AND SE OF THE SOUTHERN BLUE RIDGE AND ACRS THE NC
PIEDMONT N OF I-40. ALL ACTIVITY SHOULD DISSIPATE BY MID-EVENING.
INCREASING THICKNESS VALUES AND INCREASING SURFACE DEWPOINTS SHOULD
RESULT IN MIN TEMPS AROUND OR SLIGHTLY ABOVE NORMAL TONIGHT.

THE MAIN STORY FOR FRIDAY WILL BE THE HEAT...AS THE UPPER TROUGH
SHIFTS AWAY FROM THE EAST COAST...ALLOWING THE RIDGE AXIS TO BUILD
INTO THE REGION. OWING TO RECENT GUIDANCE PERFORMANCE...A BLEND OF
THE MAV/MET TEMPS APPEARS TO BE A SAFE BET...AND THIS WILL YIELD
MAXES ABOUT 10 DEGREES ABOVE NORMAL FRIDAY AFTERNOON...OUR WARMEST
DAY IN OVER THREE WEEKS. FORECAST SOUNDINGS TOMORROW DEPICT RATHER
WARM MID-LEVELS. HOWEVER...THERE SHOULD BE ADEQUATE CAPE TO SUPPORT
ADDITIONAL ISOLATED HIGH TERRAIN SHOWERS. THE NAM AND THE GFS ALSO
DIVE A SW TROUGH DOWN THE EASTERN PERIPHERY OF THE RIDGE...WITH SOME
QPF RESPONSE OVER THE NC PIEDMONT AS WELL...SO SLIGHT CHANCE POPS
WILL ALSO BE CARRIED EAST TO THE I-77 CORRIDOR.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AS OF 230 PM THURSDAY...UPPER RIDGE WEAKENS BUT REMAINS OVER THE
REGION SAT...THEN WEAKENS FURTHER SUN AS A SHORTWAVE APPROACHES FROM
THE NW. THE SFC PRES GRADIENT BETWEEN A DEVELOPING TROPICAL SYSTEM
IN THE W GULF AND HIGH PRES OFF THE E COAST WILL PUT THE CWA IN LGT
E TO SE FLOW THRU THE WEEKEND. WITH HIGHER THKNS AND THE S FLOW...
TEMPS WILL BE ABOVE AVG SAT AND AS MOISTURE BEGINS TO INCRS EXPECT A
CHC OF SHWRS/TSTMS...MAINLY MTNS...SAT AFTN-EVE. ECMWF SHOWS A COLD
FRONT MOVG IN FROM THE NW SUN AND WITH MOISTURE SURGING N AHEAD OF
THE SYSTEM...EXPECT CHC POPS OVER THE MTNS EARLY IN THE DAY...
SPREADING ACROSS THE CWA SUN AFTN. WITH FALLING HEIGHTS AND INCRSNG
CLOUDS LOWS WILL BE ABOVE AVG WITH HIGHS NEAR AVG SUN.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AS OF 230 PM THURSDAY...GFS DEEMED AN OUTLIER FOR THE EXTENDED PD
WITH AN ECMWF/CANADIAN BLEND USED FOR THIS FCST. AN UPPER TROF DIGS
OVER THE OH VALLEY SUN...THEN MOVES ACROSS THE E US MON-MON NIGHT
AND OFF THE E COAST TUE. AN ASSOC SFC COLD FRONT MOVES IN FROM THE W
MON WITH CHC POPS ACROSS THE CWA. FRONT SHOULD PUSH SE OF THE AREA
TUE BUT REMAIN CLOSE ENOUGH FOR MOISTURE TO BE DRIVEN UP OVER THE
BOUNDARY BY THE TROPICAL SYSTEM THAT IS EXPECTED TO DEVELOP IN THE W
GULF THIS WEEKEND...AND STAY THERE THRU MOST OF NEXT WEEK. WITH THIS
IN MIND WENT WITH SLIGHT CHC POPS...MAINLY ACROSS THE S CWA TUE-THU.
WITH LOWER HEIGHTS AND THKNS VALUES LOOK FOR BELOW AVG TEMPS MON-THU.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
AT KCLT...THERE COULD BE A FEW HIGH BASED STRATOCU LINGERING INTO
THE NIGHT...OTHERWISE THERE REMAINS JUST A SMALL CHANCE OF SEEING
A BRIEF VSBY REDUCTION JUST BEFORE SUNRISE. THE LATEST SHORT RANGE
OP MODELS AND ENSEMBLES ARE KEYING ON A SUBTLE BNDRY DRIFTING INTO
THE NC PIEDMONT FRIDAY AFTERNOON. THIS MAY WARRANT AN INCREASED TSTM
RISK...BUT AT THIS POINT WILL NOT INTRODUCE ANY CB.

ELSEWHERE...WHERE SFC DWPTS REMAINED HIGHER THIS AFTERNOON...THERE
WILL BE A CHANCE OF A PERIOD OF 5-6SM AT KAND/KHKY EARLY FRIDAY
MORNING...ESPECIALLY IF KHKY GETS A TSTM EARLY THIS EVENING.
GUIDANCE IS STILL PROGGING A PERIOD OF LIFR VSBY AT KAVL...BUT AS
WAS THE CASE LAST NIGHT...VSBY ONLY FELL TO 6SM EARLY THIS
MORNING...AND WILL STICK WITH THAT. GOING POP IS LOW ENUF TO
NOT MENTION ANY CB FOR FRIDAY AFTERNOON.

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 FORM
THE NW.
