AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
632 AM EST WED DEC 24 2008

.SYNOPSIS...
MOISTURE WILL INCREASE TODAY AS A COLD FRONT APPROACHES THE AREA
FROM THE TENNESSEE VALLEY.  THE FRONT WILL CROSS THE AREA EARLY
TONIGHT WITH HIGH PRESSURE RIDGING DOWN FROM THE NORTH FOR THE END
OF THE WEEK.  ANOTHER FRONT WILL APPROACH THIS WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
ISOLATED TO SCATTERED SHOWERS WILL CONTINUE TO DEVELOP ACRS THE CWFA
THIS MORNING WITHIN THE WAA FLOW AS WIDESPREAD CLOUDS LINGER. AS THE
MAGNITUDE AND DEPTH OF THE SW FLOW INCREASES THIS AFTERNOON...SHOWER
CVRG IS EXPECTED TO INCREASE AND PERHAPS BECOME NUMEROUS ACRS THE
UPSLOPE AREAS. WITH CLOUDS LIKELY HANGING TOUGH ALL DAY...IT WILL
NOT BE AS WARM AS THE LLVL THICKNESS INCREASE WOULD INDICATE...MAXES
GENERALLY AROUND SEASONAL NORMALS. MODERATELY FORCED AND MOIST
FRONTAL ZONE REMAINS ON TRACK TO SAG SE THRU THE CWFA TONIGHT
RESULTING IN WIDESPREAD SHOWERS AND MILD TEMPS.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
AS OF 200 AM WEDNESDAY...EXPECT THE SURFACE FRONT TO BE NEAR THE
SOUTHERN EDGE OF THE FORECAST AREA THURSDAY MORNING. THE FRONT
SHOULD DRIFT A BIT FARTHER SOUTH DURING THE DAY...ALTHO MODEL
GUIDANCE DOES NOT TAKE THE BOUNDARY QUITE AS FAR SOUTH AS EARLIER
RUNS. THE NAM STALLS THE BOUNDARY NEARBY AND KEEPS A WAVE ON
THE FRONT TO OUR SW THROUGH THE AFTERNOON AND INTO THE EVENING. AS A
RESULT...THE NAM KEEPS UPGLIDE TO THE NORTH OF THE BOUNDARY THAT
PRODUCES LIGHT PRECIP THROUGH THE AFTERNOON ACROSS MUCH OF THE FCST
AREA. THIS IS DISCOUNTED FOR THE TIME BEING AS THE GFS AND ECMWF DO
NOT HAVE THE SURFACE WAVE AND DRY US OUT BY AFTERNOON AS SURFACE
HIGH PRESSURE MOVES PAST ACROSS THE UPPER OH VALLEY. TEMPS ARE
THEREFORE KEPT MORE IN LINE WITH MAV THRU THURSDAY NITE.

MOISTURE SHOULD START RETURNING ABOVE THE OLD BOUNDARY THURSDAY
NIGHT AS THE SURFACE HIGH MOVES INTO A FAVORABLE POSITION OVER THE
ST LAWRENCE VALLEY FOR A BRIEF COLD AIR DAMMING EVENT. DID NOT SEE
MUCH OF A REASON TO MAKE ANY CHANGES TO THE FORECAST WITH REGARD TO
THIS SCENARIO. A CHANCE OF LIGHT PRECIP SHOULD DEVELOP FROM THE
SOUTH OVERNIGHT THAT SHOULD ESTABLISH THE WEDGE EARLY FRIDAY
MORNING. THE FORECAST FAVORED THE GFS/ECMWF ON FRIDAY IN KEEPING THE
CHANCE OF LIGHT RAIN THAT WOULD MAINTAIN THE WEDGE. WITH THAT IN
MIND...HAVE LOWERED THE FRIDAY HIGH TEMP ABOUT ONE CATEGORY IN THE
USUAL SPOTS FOR AN EVENT LIKE THIS.

THE PARENT HIGH CONTINUES TO MOVE STEADILY EAST OVER THE MARITIME
PROVINCES FRIDAY NIGHT...SO AT SOME POINT SUPPORT WILL BE LOST FOR
THE WEDGE. IT WILL BE MAINTAINED OVERNIGHT IN THE FORECAST WITH
EXTENSIVE CLOUDS AND A CHANCE OF LIGHT PRECIP...BUT UNCERTAINTY
CREEPS UPWARD.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
AS OF 205 AM WEDNESDAY...AS THE SURFACE CONTINUES TO MOVE FARTHER
OFF THE EAST COAST...THE REMAINING CAD WILL QUICKLY DISSIPATE.  WARM
SOUTHERLY FLOW WILL BECOME PREDOMINANT ON SATURDAY AHEAD OF THE
APPROACHING COLD FRONT.  SOME UPSLOPE FLOW ON THE WESTERN MOST
PERIPHERY OF THE OFFSHORE HIGH MAY PRODUCE SOME SHOWERS ALONG THE
SOUTHER MOST MOUNTAINS ON SATURDAY.  THE CLOUDS MAINLY NORTH OF
INTERSTATE 85 MAY HOLD DOWN TEMPERATURES A BIT BUT STILL EXPECT
HIGHS IN THE LOW TO MID 60S IN NON MOUNTAIN AREAS.  THE FRONT WILL
BE MOVING THROUGH EAST TENNESSEE ON SUNDAY WITH INCREASING SHOWERS
FROM THE WEST.  FRONTAL PASSAGE OVER OUR AREA SHOULD BE LATE SUNDAY
AS HPC CONTINUES TO BE CONSISTENT WITH THE GFS. SOME TIMING
DIFFERENCES BETWEEN THE GFS AND ECMWF ON THE FRONTAL PASSAGE.  THE
GFS HAS THE FRONT DISSECTING OUR FORECAST AREA FROM NE TO SW AT 00Z
MONDAY.  THE ECMWF HAS IT STILL OVER CENTRAL TENNESSEE AT THAT
TIME.  THE EC DOES NOT BRING THE FRONT THROUGH UNTIL EARLY MONDAY.
ALL PRECIP SHOULD BE IN THE FORM OF RAIN.

AS THE FRONT MOVES OFF THE CAROLINA COAST ON MONDAY...HIGH PRESSURE
WILL BE BUILDING IN FROM THE MISSISSIPPI AND OHIO VALLEYS.  DRY
WEATHER ON MONDAY AND TUESDAY WITH NEAR NORMAL TEMPERATURES.  BOTH
THE GFS AND ECMWF SHOW A STRONG SHORTWAVE DIPPING DOWN FROM THE
UPPER MISSISSIPPI AT 00Z WEDNESDAY AND APPROACHING THE NC MOUNTAINS
VERY LATE TUESDAY NIGHT.  I HAVE INCREASED CLOUDS A BIT FOR THE NC
MOUNTAINS TOWARD 12Z WEDNESDAY...BUT LOOKS LIKE ANY PRECIP WOULD
HOLD OFF UNTIL DAY TIME WEDNESDAY.

&&

.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...THERE IS OVERWHELMING GUIDANCE SUPPORT THAT THE RECENT
IMPROVING TREND WILL BE SHORT-LIVED...AND WILL REDEVELOP CIG
RESTRICTIONS LATER THIS MORNING AS WINDS PICK UP A SOUTHERLY
DIRECTION AND INCREASE INTO THE AFTERNOON. STILL THINK THAT SHOWER
CVRG WILL BE SCATTERED ENOUGH TO LEAVE OUT A MENTION UNTIL FRONTAL
BAND MOISTURE HEADS INTO THE PIEDMONT THIS EVENING. COLD FRONTAL
PASSAGE AND WIND SHIFT TO NORTHERLY IS FCST DURING THE PRE-DAWN
HOURS THURSDAY.

ELSEWHERE...KAVL IS IN THE WORST SHAPE THIS MORNING...BUT AS
SOUTH WINDS INCREASE...WOULD EXPECT CIGS AND PREDOMINATE
VSBY TO IMPROVE...PERHAPS NOT GREATER THAN MVFR...AS SHOWER
CVRG INCREASES INTO THE AFTERNOON HOURS. THE REST OF THE
PIEDMONT TAFS SHOULD MAINTAIN CURRENT FLIGHT RESTRICTION LEVEL
TODAY...ALTHOUGH THE GUIDANCE DOES POINT TO A PERIOD OF IFR
CONDITIONS AS THE WAA FLOW INCREASES THIS MORNING. WILL TIME
CATEGORICAL INCREASE TO SHOWERS AS FRONTAL BAND DEVELOPS INTO THE
FOOTHILLS THIS EVENING WITH A WIND SHIFT PROBABLE DURING THE PRE-
DAWN HOURS THURSDAY.

OUTLOOK...EXPECT IMPROVING WX CONDITIONS CHRISTMAS DAY IN THE WAKE
OF THE COLD FRONT. RAIN CHANCES AND FLIGHT RESTRICTION PROBABILITIES
WILL BE INCREASING AGAIN ON FRIDAY. SMALL SHOWER CHANCES AHEAD OF
THE NEXT COLD FRONT ON SATURDAY WILL INCREASE THROUGH SUNDAY.
