AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
139 PM EDT WED OCT 27 2010

.SYNOPSIS...
A COLD FRONT OVER THE AREA WILL MOVE SLOWLY SOUTHEAST TODAY AND WILL
BE EAST OF THE FORECAST AREA BY EARLY THURSDAY. CANADIAN HIGH
PRESSURE WILL BUILD IN FROM THE NORTH LATE ON THURSDAY AND REMAIN
OVER THE AREA THROUGH  THE WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
AT 12Z QUASI STATIONARY FRONTAL BOUNDARY WAS ANALYZED THROUGH
WESTERN NC WITH A WEAK WAVE OVER EASTERN ALABAMA IN ASSOCIATION WITH
AN UPPER IMPULSE ALOFT. THIS WAVE WILL RIPPLE NORTHEAST AND EXPECT
COVERAGE OF CONVECTION TO INCREASE DURING THE AFTERNOON. CURRENT IR
SATELLITE SHOWS COOLING CLOUD TOPS OVER AL/GA AND REGIONAL RADAR
SHOWS STRONG CELLS DEVELOPING. HENCE...EXPECT ANOTHER ROUND OF
SIGNIFICANT CONVECTION THIS AFTERNOON. DECENT SHEAR/HELICITY STILL
EXISTS TO SUPPORT SEVERE STORMS WITH THE POSSIBILTY OF TORNADIC
ACTIVITY. LATEST MCD FROM SPC INDICATES THAT ANOTHER TOR WATCH MAY
BE FORTHCOMING. MINMOR ADJUSTMENTS TO TEMP/DEWPOINT/WIND BASED ON
CURRENT LAV.

ANOTHER ATTRIBUTE OF THE SLOW MOVING FRONTAL ZONE WILL BE THE ONGOING
LIKELIHOOD OF TRAINING CELLS. GIVEN THE RECENT LOCALLY HEAVY RAINFALL
ACRS THE NW HALF OF THE CWFA IT IS NOT UNREASONABLE TO ASSUME THAT
ISOLATED EXCESSIVE RAINFALL MAY DEVELOP.

THERE IS SOME DISCREPANCY IN MODEL SOLUTIONS FOR TONIGHT...AS 12Z
NAM FORECASTING A MCS TYPE QPF EVENT ALONG SLOW MOVING FRONTAL ZONE.
FOR NOW WILL CONTINUE TO FAVOR A SLOWLY PROGRESSIVE PATTERN
OVERNIGHT WHICH WILL PUSH THE HIGHER POPS OUT OF THE FORECAST AREA
AFTER 06Z.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
AS OF 320 AM WEDNESDAY...MODELS CONTINUE TO SHOW DIFFERING SOLUTIONS
WITH THE GFS AND NAM MOVG THE FRONT THRU THE CWA BY AROUND 12Z
THU...BUT THE ECMWF KEEPS IT OVER THE AREA LONGER. KEPT SLIGHT CHC
POPS THU MRNG TO ACCOUNT FOR TIMING UNCERTAINTY...EXPECT DRY COND
FRI AND COOL HIGH PRES BUILDS IN FROM THE NW. WINDS WILL BE GUSTY
FROM THE W-NW ACROSS THE AREA THU...THEN GUSTY AGAIN OVER THE MTNS
FRI. TEMPS REMAIN WELL ABOVE AVG THU COOLING TO A FEW DEG BELOW AVG
FRI. IT STILL LOOKS LIKE THERE WILL BE SOME FREEZING TEMPS OVER THE
NC MTNS EACH MORNING...WITH MORE A WIDESPREAD MTN FREEZE...WITH
FROST OVER THE NC FOOTHILLS AND PIEDMONT FRI MRNG.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
AS OF 130 PM WEDNESDAY...WHILE THEY GO ABOUT IT IN SOMEWHAT
DIFFERENT WAYS...THE ECMWF AND GFS AGREE IN DEVELOPING A HIGH
AMPLITUDE RIDGE OVER THE WEST COAST...WHICH RESULTS IN THE
DOWNSTREAM DEVELOPMENT OF A SHARP TROUGH OVER THE ERN US. BOTH
MODELS ARE TRENDING TOWARD THE DEVELOPMENT OF A CUT OFF UPPER LOW
OVER THE LOWER MISSISSIPPI RIVER VALLEY FOR TUE AND WED ON NEXT WEEK.

WHILE THE GFS APPEARS TO CUT OFF THE LOW TOO FAR TO THE SOUTH...AND
THE EC IS PROBABLY TAKING TOO MUCH ENERGY INTO THE BASE OF THE
TOUGH...THE OVERALL SCENARIO POTENTIALLY LOOKS QUITE WET ACROSS THE
WESTERN CAROLINAS AND NE GA FOR TUE AND WED OF NEXT WEEK. AS FAR
SOUTH AS THE LOW DIGS...AND WITH SIGNS OF COLD AIR DAMMING IN THE
SFC PRESSURE FIELD...THIS LOOKS TO BE MORE OF A HEAVY RAIN THAN A
SEVERE EVENT...THOUGH THAT COULD CERTAINLY CHANGE.

THE WEATHER BEFOREHAND...FOR SUNDAY AND MONDAY...LOOKS DRY AND MILD.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
AT KCLT...CURRENT RADAR TRENDS SUPPORT THE IDEA THAT A FRONTAL WAVE
WILL MOVE ALONG THE STALLED BOUNDARY TO THE NORTH AND SPREAD
WIDESPREAD SHOWERS/STORMS INTO THE CLT AIRSPACE BY LATE AFTERNOON.
LATEST HRRR SUGGESTS THAT THE BEST WINDOW FOR THUNDERSTORMS WILL BE
21Z-00Z. A SEVERE THUNDERSTORM WITH STRONG WINDS AND CAPABLE OF
PRODUCING A TORNADO CANNOT BE RULED OUT. LOW VFR CEILINGS WILL LOWER
TO IFR/MVFR IN STORMS. ALL GUIDANCE SUPPORTS LOW IFR CEILINGS LATE
TONIGHT...THEN LIFTING SLOWLY AFTER 12Z. WINDS WILL GRADUALLY VEER
TO THE W-SW BY LATE TONIGHT.

ELSEWHERE...EXPECT COVERAGE OF SHOWERS TO INCREASE ALONG WITH
THUNDERSTORM DEVELOPMENT ACROSS UPSTATE SC FOR THE REMAINDER OF THE
AFTERNOON. ALSO CAN'T RULE OUT A SEVERE THUNDERSTORM CAPABLE OF
PRODUCING A BRIEF TORNADO. SCATTERED SHOWERS WILL REMAIN IN THE
KAVL/KHKY UNTIL LATE EVENING WITH JUST AN OUTSIDE CHANCE OF A
THUNDERSTORM. SHOWERS/STORMS WLL TAPER OFF AFTER MIDNIGHT. ALL
GUIDANCE SUGGESTS THAT CEILINGS WILL LOWER TO LOW IFR LATE TONIGHT
AND THEN LIFT/SCATTERED THU MORNING. IFR FOG ALSO IS EXPECTED AT
KAVL/KHKY EARLY THU.

OUTLOOK...DRY HIGH PRESSURE WILL BE FEATURED FRIDAY THRU SUNDAY WITH
NO RESTRICTIONS OTHER THAN EARLY MORNING MOUNTAIN VALLEY FOG POSSIBLE.

&&

.GSP WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
