AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
248 PM EDT TUE SEP 9 2008

.SYNOPSIS...
AN APPROACHING COOL FRONT WILL MOVE THROUGH THE CAROLINAS TODAY INTO
WEDNESDAY. ON THURSDAY A COOLER WEDGE OF HIGH PRESSURE WILL BUILD
BACK IN ACROSS AREA. TEMPERATURES WILL RETURN TO NEAR NORMAL ALONG
WITH AN UNSTABLE ATMOSPHERE MAKING FOR A CHANCE OF AFTERNOON
THUNDERSTORMS OVER THE WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AHEAD OF THE APPROACHING COLD FRONT...STRONG UPPER LEVEL DIVERGENCE
WILL MOVE INTO THE FORECAST AREA FROM THE SOUTHWEST STARTING AROUND
21Z. THIS FORCING WILL COMBINE WITH THE BEST 850 TO 500 MB
DIFFERENTIAL POSITIVE VORTICITY ADVECTION TRAVERSING THE NORTHERN
TIER OF THE FORECAST AREA DURING THAT 21Z TO 00Z AS WELL. THUS
WIDESPREAD COVERAGE IS EXPECTED ACROSS THE NRN HALF OF THE FORECAST
AREA...WITH SCATTERED TO NUMEROUS COVERAGE SOUTH.

CONVECTION HAS STARTED ALONG THE BLUE RIDGE AND OVER THE MOUNTAINS
THIS AFTERNOON...AND THIS SHOULD BE QUICKLY DRIVEN EASTWARD THROUGH THE
PIEDMONT THROUGH THE EVENING HOURS. RICH LOW LEVEL EQUIVALENT
POTENTIAL TEMPERATURES...LINGERING MID LEVEL DRY AIR...UPPER
SUPPORT...AND 20 TO 25 KT OF DEEP LAYER SHEAR WILL MAXIMIZE THE
SEVERE THREAT OVER THE INTERSTATE 77 CORRIDOR THROUGH EARLY
EVENING...AND A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED.

THE APPROACHING COLD FRONT WILL LAY OVER ACROSS THE NRN TIER OF THE
FORECAST AREA TONIGHT. THE NAM IS THEN MORE AGGRESSIVE IN PULLING
THE BOUNDARY SOUTHWARD THROUGH THE CWFA THROUGH EARLY WEDNESDAY AS
ISENTROPIC LIFT OVER THE COLD WEDGE SETS UP. THIS MORE AGGRESSIVE
AND COOLER SOLUTION OF THE NAM...WITH ITS TERRAIN HANDLING...SEEMS
THE BETTER ANSWER AND WILL BE FOLLOWED THROUGH WEDNESDAY. SOME
DEGREE OF COUPLED UPPER JET FORCING LINGERS THROUGH WEDNESDAY...AND
WEAK RIPPLES IN THE WSW UPPER FLOW WILL CONTINUE TO AFFECT THE
REGION THROUGH THE DAY. MAX TEMPERATURES WILL BE ONE TO TWO
CATEGORIES BELOW THE COOLER MOS IN MOST LOCATIONS WED.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 2 PM TUESDAY...COOL AIR DAMMING EVENT FOR WED AND THURS STILL
APPEARS TO BE ON TRACK. THE CENTER OF HIGH PRESSURE IS STILL FCST TO
BUILD OVER THE NORTHEAST UNITED STATES DURING THIS TIME PERIOD. NEW GFS
AND NAM12 DO APPEAR TO HAVE THE COOL AIR WEDGE BREAK DOWN A BIT MORE
ABRUPTLY ON FRIDAY AS IT SHIFTS WINDS OUT OF THE SOUTH BY EARLY
AFTERNOON. POPS LOOK EVEN MORE FAVORABLE LATE WED AND EARLY THURS AS
LLVL MOISTURE AND FORCING SHOW MORE PROMISE FOR NOTABLE PRECIP
ESPECIALLY OVER THE PIEDMONT. ALSO INCREASED POPS FRIDAY AFTERNOON
AND EVENING OVER THE HIGHER ELEVATIONS TO ACCOUNT FOR THE LIKELIHOOD
OF ENHANCED UPSLOPE FLOW FROM THE SE COUPLED WITH DECENT CAPE
VALUES. WITH THESE INGREDIENTS IN PLACE...THE POSSIBILITY FOR SEVERE
CONVECTION IS PRESENT. TEMP VALUES DID NOT REQUIRE MUCH MODIFICATION
FOR THURS...WHILE VALUES WERE INCREASED A FEW DEGREES FOR THE LATTER
PART OF FRI AND EARLY SAT IN ORDER TO REFLECT A MORE RAPID WEAKENING
AND RETREAT OF THE COOL AIR WEDGE. IF THE 12Z GFS REMAINS ACCURATE
WE SHOULD EASILY BE ABLE TO REBOUND BACK TO NORMAL MAX TEMPS ON SAT.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 200 PM TUESDAY...EXTENDED PORTION OF THE FORECAST WILL BEGIN
WITH AN UPPER ANTICYCLONE BUILDING OVER THE SE U.S. AS IKE MOVES
INTO THE WESTERN GULF/TX. THIS WILL BRING A RETURN TO SUMMERLIKE
CONDITIONS OVER THE FORECAST AREA THIS WEEKEND WITH TEMPERATURES
REBOUNDING TO ABOVE AVERAGE VALUES. FOR SAT AND SUNDAY...IT SHOULD
BE GENERALLY DRY...EXCEPT FOR SOME ISOLATED LATE AFTERNOON
THUNDERSTORMS ACROSS THE MOUNTAINS/FOOTHILLS. 12Z GFS HAS COME MORE
INTO LINE WITH THE 00Z ECMWF IN REGARD TO THE REMNANTS OF IKE AND
THE TIMING OF A COLD FRONT FOR THE EARLY NEXT WEEK. GFS NOW CAPTURES IKE
AS WELL IN WESTERLIES AND MOVES IT QUICKLY NE ALONG A FRONTAL
BOUNDARY AND INTO THE LOWER GREAT LAKES BY MONDAY. THIS FRONT IS
FORECAST TO REACH THE CAROLINAS AND SOUTHERN APPALACHIANS DURING
THE DAY ON MONDAY. THEREFORE...HPC SOLID CHANCE POPS LOOK GOOD FOR
MONDAY. GUIDANCE HINTING THAT FRONT MAY STALL IN THE VICINITY ON TUE
WHICH WOULD KEEP THE THREAT OF PRECIP OVER THE REGION INTO TUE.
STAYED CLOSE TO HPC GUIDANCE TEMPS. FOR POPS...GENERALLY WENT LOWER
THAN HPC FOR THE WEEKEND AND SHOWED DIURNAL TRENDS. STAYED CLOSE TO
HPC POPS FOR MON/TUE.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
WIDESPREAD SHOWERS AND THUNDERSTORMS WILL DEVELOP ACROSS THE
NORTHERN HALF OF THE TERMINAL FORECAST AREA THROUGH THIS EVENING AS
UPPER JET AND VORT LOBE SUPPORT MOVE IN FROM THE WEST AHEAD OF THE
APPROACHING FRONT. LOCATIONS THAT HAVE IMPROVED TO VFR WILL LIKELY
QUICKLY TRANSITION BACK TO MVFR CIGS THIS EVENING IN ANY SHOWERS AND
TSTMS. THE STORMS WILL MAINLY AFFECT TAF SITES FROM 19Z WEST TO 00Z
EAST THIS EVENING.

UPGLIDE OVER THE DEVELOPING COLD WEDGE WILL STEADILY LOWER CEILINGS
OVERNIGHT WITH IFR CONDITIONS POSSIBLE ONCE THE STEADY RAIN DEVELOPS
WED MORNING. LITTLE TO NO IMPROVEMENT IN THE COLD AIR DAMMING REGION
IS EXPECTED THROUGH THE DAY.

OUTLOOK...SIGNIFICANT CEILING AND VISIBILITY RESTRICTIONS WILL
LIKELY PERSIST FROM WEDNESDAY NIGHT THROUGH MUCH OF THURSDAY AS
MOISTURE CONTINUES TO MOVE NORTHWARD OVER A WEDGE OF HIGH PRESSURE.
THE WEDGE MAY GRADUALLY ERODE FROM FRIDAY THROUGH SUNDAY...BUT WITH
SCATTERED CONVECTION LIKELY DEVELOPING EACH AFTN AND EVENING THROUGH
THE PERIOD.
