AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
234 PM EDT MON SEP 27 2010

.SYNOPSIS...
LOW PRESSURE WILL MOVE NORTHEAST AND AWAY FROM OUR AREA TONIGHT AND
TUESDAY AS WEAK HIGH PRESSURE BUILDS INTO THE CAROLINAS FROM THE
WEST.  A PLUME OF TROPICAL MOISTURE WILL MOVE NORTHWARD ALONG THE
COASTAL FRONT ON WEDNESDAY AND THURSDAY. ANOTHER WEAK COLD FRONT
WILL MOVE INTO THE REGION FROM THE NORTHWEST THURSDAY NIGHT AND THEN
ANOTHER WEAK COLD FRONT ON SATURDAY NIGHT.

&&

.NEAR TERM /THROUGH TUESDAY/...
CURRENT RADAR SHOWS BULK OF THE RAIN OVER THE EASTERN HALF OF THE
FORECAST AREA IN AREA OF BEST UPPER DIVERGENCE. RAINFALL TOTALS
TODAY HAVE BEEN MODEST AT BEST AND NO FLOOD ISSUES HAVE OCCURRED.
LOOKS LIKE THE I-77 CORRIDOR WILL STILL HAVE THE OPPORTUNITY FOR
SOME HEAVY RAINFALL LATE THIS AFTERNOON AND EVENING AS UPPER LOW
BEGINS TO KICK NE AND SOME DECENT PVA OCCURS. THEREFORE...WILL HANG
ONTO THE FLOOD WATCH ALONG THE I-77 CORRIDOR IN NC  MAINLY FOR THE
URBAN FLOOD THREAT THERE. STILL EXPECTING TO SEE POTENTIALLY 1-2
INCHES OF RAIN. ALSO THERE STILL IS A SEVERE CONCERN IN THE
EASTERN/SOUTHERN PIEDMONT AS WEDGE ERODES AWAY WITH SURFACE BASED
CAPE INCREASING TO AROUND 500J LATE THIS AFTERNOON ALONG WITH
ROBUST HELICITIES. THE THREAT IS FOR QLCS FORMATION WHICH COULD SPAWN
AN ISOLATED BRIEF TORNADO. ALSO...FAR WESTERN NC BEGINNING TO
DESTABLIZE NEAR UPPER LOW...BUT EXPECT SUB-SEVERE THUNDER THERE IN
SCATTERED CONVECTION. SCATTERED SHOWERS WILL CONTINUE ELSEWHERE INTO
THE EVENING AS A GOOD SHOT OF PVA MOVES ACROSS THE AREA AS UPPER LOW
MOVES NE.

AS UPPER LOW MOVES TO WESTERN VA BY 06Z....WESTERN CAROLINAS/NE GA
WILL BE DRY SLOTTED WITH PRECIP EXITING TO THE E. AREAS OF
FOG/STRATUS EXPECTED TO DEVELOP LATE TONIGHT TO PRECLUDE WIDESPREAD
CLEARING. HOWEVER...DRYER AIR MIXING DOWN EARLY ON TUE WILL ALLOW
FOR CLEARING CONDITIONS EVERYWHERE BY MID MORNING. STAYED CLOSE TO
MET MOS FOR MIN/MAX TEMPS.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 230 PM EDT MONDAY... TUESDAY NIGHT WILL BEGIN WITH WEAK HIGH
PRESSURE OVER THE REGION. AXIS OF SHARP 500 MB TROUGH WILL BE JUST
TO OUR WEST WITH STRONG SHORT WAVE ENERGY DIVING SOUTHWARD THEN
MOVING INTO BASE OF TROUGH OVERNIGHT BEFORE MOVING EAST OF AREA
THURSDAY. WILL CARRY SLIGHT POPS IN MOUNTAINS TO REFLECT COMBINATION
OF SOME QG FORCING WITH TROUGH AND A LIMITED SUPPLY OF MOISTURE.
DIFFERENCES IN MODEL GUIDANCE OF DEVELOPMENT ALONG EAST COAST FRONT
CREATE CHALLENGES NAILING DOWN DETAILS OF FORECAST WEDNESDAY INTO
THURSDAY.  BOTH MODELS INDICATE A SURFACE LOW MOVING FROM VICINITY
OF CUBA NORTHEASTWARD BUT THEY DIFFER IN PLACEMENT OF THE CENTER. BY
00Z THURSDAY... NAM HAS MAIN CENTER NEAR KEY WEST WITH A WAVE OFF
COASTAL SOUTH CAROLINA. GFS PLACES LOW CENTER OFF CENTRAL FLORIDA
COAST WITH FRONTAL TROUGH NORTH ALONG CAROLINA COAST. NAM SURFACE
WAVE CONTRIBUTES TO MOISTURE SPREADING A LITTLE FURTHER INLAND THAN
GFS. PLAN TO BASICALLY SPLIT THE DIFFERENCE BETWEEN THE TWO AND
INCREASE POPS IN OUR FAR EASTERN ZONES... BUT ONLY GO WITH VERY LOW
CHANCE POPS AT THIS TIME. BY LATE IN THE DAY THURSDAY... BOTH NAM
AND GFS MOVE THE SIGNIFICANT MOISTURE FAR ENOUGH TO THE NORTHEAST SO
NO POPS WILL BE CARRIED AFTER 18Z. FORECAST TEMPERATURES WILL BE A
BLEND OF GFS AND NAM MOS.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 230 PM EDT MONDAY...THE ECMWF IS GENERALLY FAVORED IN THE
MEDIUM RANGE.  THE GEM IS RATHER EXTREME TO START THIS PERIOD AT 00Z
FRIDAY WITH BIG TROPICAL PLUME PASSING NORTH OF THE CAROLINAS WITH
ANOTHER CLOSED OFF LOW OVER AL/MS TO OUR WEST.  EVEN THE EXTREME GEM
TRENDS TOWARD THE ECMWF IN THE WEEKEND.  BROAD SURFACE HIGH PRESSURE
WILL BE MOVING OUT OF SOUTHERN CANADA ON FRIDAY AND BE OVER THE
WESTERN GREAT LAKES SUNDAY.  COOL AND DRY NORTHEAST FLOW CAN BE
EXPECTED THROUGH THE REST OF THE PERIOD.  TEMPERATURES WILL BE NEAR
NORMAL FRIDAY AND THEN DROP OFF INTO EARLY NEXT WEEK TO AROUND 8
DEGREES BELOW NORMAL. A SHARP 500MB TROUGH WILL ACCOMPANY THE
SURFACE HIGH.  THE TROUGH WILL STILL BE DIGGING TO START NEXT WEEK
ON THE ECMWF...BUT QUICKLY SHIFTS OFF THE EAST COAST ON THE GFS AS
IT HINTS AT ANOTHER CLOSED LOW OVER LOWER MISSISSIPPI.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
AT KCLT...IFR CIGS SHOULD BE THE RULE AT LEAST UNTIL ABOUT MIDNIGHT.
COULD SEE A BRIEF TEMPO HIGHER. LULL IN RAIN ACTIVITY AT THE MOMENT
BUT RADAR INDICATES THAT HEAVIER SHOWERS WILL MOVE BACK OVER
AIRFIELD BY ABOUT 20Z. SOUNDINGS SHOW SOME INSTABILITY LATE THIS
AFTERNOON...SO CANNOT RULE OUT THUNDER SO HAVE MENTIONED CB 20Z-23Z.
LIKELY TO SEE LOW CIGS BREAK FOR A PERIOD AFTER MIDNIGHT AS DRY SLOT
MOVES THROUGH...BUT GUIDANCE SUGGGESTS THAT AT LEAST MVFR FOG AND
PERIOD OF IFR CIGS A GOOD BET TOWARD SUNRISE...THEN RAPIDLY
IMPROVING TO UNRESTRICTED BY 14Z AS WINDS TURN NW.

ELSEWHERE...IFR/LIFR CIGS WILL BEGIN TO GRADUALLY LIFT TO MVFER BY
LATE AFTERNOON AS BEST FORCING/SHOWERS MOVE EAST. AS DRY SLOT
ARRIVES COULD SEE A PERIOD OF VFR. GUIDANCE SUGGESTS THAT AT LEAST
MVFR FOG AND SOME PATCHY STRATUES WILL OCCUR TOWARD SUNRISE AND THEN
RAPIDLY IMPROVE TO UNRESTRICTED AFTER SUNRISE. KAVL LIKELY TO SEE
LIFR CONDITIONS LATE TONIGHT.

OUTLOOK...MUCH DRIER/VFR CONDITIONS ARE EXPECTED THROUGH THE
REMAINDER OF THE WEEK.
