AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
247 PM EDT THU AUG 30 2007
.SYNOPSIS...
A WEAK COLD FRONT WILL ENTER THE TENNESSEE VALLEY TONIGHT...REACHING
OUR AREA BY FRIDAY NIGHT...PUSHING SOUTH OF THE AREA FOR THE WEEKEND.
&&
.NEAR TERM /THROUGH FRIDAY/...
LATEST RUC AND NAM RUNS DEVELOP GOOD LLVL CONVERGENCE (1000-850 MB
LAYER) ACROSS THE UPSTATE AND UP INTO THE LEE SLOPES OF THE NC MTNS
AND FOOTHILLS. LATEST TERMINAL DOPPLER RADAR IMAGERY FROM TCLT SHOWS
DEEP LAYER NNE FLOW...WHILE FLOW OVER THE THE WESTERN PART OF THE
UPSTATE IS MORE WESTERLY. THEREFORE IT LOOKS LIKE THE NAM AND RUC
WIND FIELDS ARE VERIFYING WELL SO FAR. AS A RESULT...I/LL UP POPS
ACROSS THE UPSTATE AND INTO THE NC MTNS AND WRN FOOTHILLS...WHILE
DROPPING THEM A BIT IN THE I-77 CORRIDOR OF NC.
THERE HAS BEEN ABUNDANT MID LEVEL CLOUD COVER THIS MORNING AS THE
AREA OF DEEP LAYER RH THAT HAS BEEN TEASING US JUST TO THE WEST THE
PAST COUPLE DAYS HAS FINALLY OVERSPREAD A GOOD BIT OF THE FORECAST
AREA. MOIST 12 UTC SOUNDINGS SHOULD YIELD QUITE A BIT OF CONVECTIVE
ACTIVITY THIS AFTERNOON AHEAD OF A MID LEVEL SHORT WAVE MOVING OVER
ERN TN ATTM...EVEN WITHOUT FULL SUN. HOWEVER...THE MORE HEATING WE
SEE...THE MORE WIDESPREAD WL BE THE CONVECTTION.
WITH APPROACHING FRONT EXPECT CONVECTION TO CONTINUE OVERNIGHT
BEFORE TAPERING OFF SOMEWHAT TOWARD DAYBREAK. MORNING LOWS WILL
SETTLE AROUND 70 PIEDMONT...UPPER 50S TO MID 60S MTNS.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
A WEAK UPPER LEVEL LOW WILL LINGER OVER THE EASTERN GULF STATES
SATURDAY AND SUNDAY...WHILE AN UPPER TROUGH TO THE NORTH
DEAMPLIFIES. THE SURFACE REFLECTION OF THIS LOW IS DEPICTED BY THE
MODELS CLOSE TO THE GULF COAST. A WEAK COLD FRONT WILL SLOWLY SOUTH
INTO THE AREA FRIDAY NIGHT...INTRODUCING AN EASTERLY UPSLOPE FLOW
INTO HIGHER TERRAIN THAT PERSISTS THROUGH SUNDAY BEFORE THE BOUNDARY
AND ITS ASSOCIATED MOISTURE MOVE WELL SOUTH OF THE AREA. CHANCE POPS
WILL BE CARRIED WITH DAYTIME HEATING...MAINLY ALONG THE BLUE
RIDGE...WITH SLIGHT CHANCE POPS EACH NIGHT. TEMPERATURES WILL TREND
FROM JUST ABOVE NORMAL SATURDAY TO SLIGHTLY BELOW NORMAL SUNDAY AS
THE COOLER AIR MASS EDGES SOUTH.
&&
.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
THE EXTENDED PERIOD FEATURES THE PROGRESSION OF AN EAST COAST UPPER
TROUGH...FOLLOWED BY THE AMPLIFICATION OF AN UPPER RIDGE OVER THE
SOUTHERN AND CENTRAL APPALACHIANS. A STATIONARY FRONT WILL BE
LOCATED ALONG THE EASTERN GULF COAST FROM MONDAY THROUGH
WEDNESDAY...WITH A SURFACE RIDGE CENTERED OFF THE MID ATLANTIC COAST
EXTENDING OVER OUR AREA. INITIALLY MOISTURE WILL BE CONCENTRATED
ALONG THE GULF COAST AS AN UPPER LEVEL COL BETWEEN THE TROUGH AND
RIDGE KEEPS ANY ISENTROPIC UPGLIDE OVER THE BOUNDARY TO OUR SOUTH.
POPS WILL NOT BE CARRIED EARLY IN THE EXTENDED FORECAST. AS THE
UPPER RIDGE AMPLIFIES...A WEAK SOUTHERLY FLOW WILL TRANSPORT
MOISTURE NORTH OVER THE SURFACE RIDGE...INCREASING CLOUDS AND
SUPPORTING SMALL POPS WITH TIME. BY THURSDAY THE FRONT WASHES
OUT...BUT A CONTINUED EASTERLY LOW LEVEL FLOW WILL HELP OFFSET
TEMPERATURES GAINS ASSOCIATED WITH HEIGHT RISES UNDER THE UPPER
RIDGE.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
SHRA AND TSTMS SHUD BE FAIRLY WIDESPREAD THIS AFTERNOON AND EVENING
AND I HAVE VCTS AT ALL TAF SITES AT VARIOUS TIME OVER THE NEXT 6
HORUS OR SO. PREVAILING FLOW ACROSS THE REGION IS NE ATTM...AND THIS
GENERAL FLOW SHOULD CONTINUE FOR THE NEXT 24 HRS...THOUGH WINDS WILL
BE VERY LIGHT OVERNIGHT. PATCHY LOW CLOUDS ARE CERTAINLY
POSSIBLE...BUT FORCING IS NOT STRONG ENOUGH TO ME TO INCLUDE
ANYTHING IN THE TAFS. AS FOR VSBYS...HAVE MOST SITES GOING DOWN LATE
WITH MVFR FOG/HAZE...SIMILAR TO THE PAST FEW NIGHTS. HOWEVER...ANY
SITES THAT SEE APPRECIABLE RAINFALL WILL LIKELY FALL MUCH MORE
OVERNIGHT.
AVIATION OUTLOOK...THRU WED. SCT TSTMS POSSIBLE FRI-SAT AS A FRONT
MOVES SLOWLY ACROSS THE CWA. FRONT IS EXPECTED TO STALL S OF THE
AREA SUN...WITH LITTLE CHANCE OF CONVECTION MON-WED. MVFR MORNING
