AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
337 AM EDT THU JUN 14 2012

.SYNOPSIS...
A WEAK COLD FRONT WILL MOVE SOUTHWARD ACROSS THE REGION TODAY.
HIGH PRESSURE IS THEN EXPECTED TO REMAIN OVER THE WESTERN CAROLINAS
AND NORTHEAST GEORGIA INTO EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
A BACK DOOR COLD FRONT CONTINUES TO PUSH TO SOUTHWEST...ACROSS THE
FORECAST AREA EARLY THIS MORNING. SCT SHOWERS AND A FEW
THUNDERSTORMS ARE DEVELOPING ALONG THE FRONT...AS WELL AS IN THE
INCREASING UPSLOPE FLOW ACROSS BLUE RIDGE AHEAD OF THE FRONT.
CONSIDERABLY DRIER AIR IS FILTERING IN BEHIND THE FRONT...THOUGH IT
WILL BE SEVERAL MORE HOURS UNTIL THE DRY AIR PUSHES ALL THE WAY
ACROSS THE FA. UNTIL THE DRY AIR MOVES IN...THE SHOWERS WILL
CONTINUE. IN FACT...THEY SHOULD INCREASE IN COVERAGE OVER THE NEXT
FEW HOURS ALONG THE EASTERN ESCARPMENT OF THE BLUE RIDGE.

LATER TODAY...CONVECTION IS EXPECTED TO REDEVELOP OVER THE SOUTHWEST
NC MTNS. HOWEVER...THE BEST LLVL CONVERGENCE AND INSTABILITY SHIFTS
IN ERN TN. SO WHILE THUNDERSTORMS SHOULD INITIATE IN THE FORECAST
AREA...THEY SHOULD DRIFT OUT OF THE FORECAST AREA BEFORE TOO
LONG...AND I/D EXPECT ANY SEVERE THREAT TO BE WEST OF THE FORECAST
AREA THIS AFTERNOON. OTHERWISE IT WILL BE A NICE DAY WITH LOWER
DEWPOINTS AND MAX TEMPS RUNNING A FEW DEGREES BELOW NORMAL. THERE
WILL BE QUITE A BIT OF ALTO-CU UNDER AN INVERSION UP AROUND 7KFT
THIS MORNING. BY THE AFTERNOON I THINK THE PIEDMONT WILL LARGELY
CLEAR OUT...THOUGH THE BROKEN CLOUD COVER WILL LIKELY LAST THROUGH
THE DAY ACROSS THE FOOTHILLS AND MOUNTAINS.

UPSLOPE FLOW WILL STRENGTHEN LATE TONIGHT. A FEW SHRA WILL BE
POSSIBLE THROUGH THE NIGHT ACROSS THE BLUE RIDGE AND LOWER CLOUD
COVER MAY DEVELOP LATE AT NIGHT IN THIS AREA AS WELL.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY/...
AS OF 310 AM THURSDAY...BOTH THE GFS AND ECMWF INDICATE THAT THE
FORECAST AREA WILL REMAIN BETWEEN A 588 DM RIDGE OVER THE CENTRAL
CONUS AND AN AMPLIFIED TROUGH OVER THE WESTERN ATLANTIC THROUGH THE
SHORT TERM. AT THE SFC...AN ELONGATED RIDGE OF HIGH PRESSURE WILL
SUPPLY STEADY NORTHEAST WINDS EAST OF THE APPALACHIANS. FORECAST
SOUNDINGS DURING FRIDAY AND SATURDAY AFTERNOONS INDICATE THAT A
SIGNIFICANT H8 TO H75 INVERSION WILL REMAIN OVER THE REGION. THE
INVERSION COMBINED WITH DEEP DRY AIR SHOULD YIELD LITTLE TO NO CAPE
ACROSS THE PIEDMONT AND FOOTHILLS...POSSIBLY RANGING NEAR 100 J/KG
ACROSS THE MTNS. I WILL FORECAST DRY CONDITIONS EAST OF THE
MTNS...WITH SLIGHT CHC ACROSS THE MTNS AND RIDGE TOP CHC ACROSS
WESTERN NC BOTH AFTERNOONS. TEMPERATURES ARE FORECAST TO RANGE
BETWEEN 2 TO 4 DEGREES BELOW NORMAL.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
AS OF 330 AM THURSDAY...SUNDAY AND MONDAY...H5 RIDGE AXIS WILL PIVOT
EAST ACROSS THE MTNS THROUGH THE PERIOD. SFC RIDGING WILL CONTINUE
ACROSS THE CWA...WITH STEADY NE LLVL FLOW. GFS FORECAST SOUNDINGS
INDICATE WIDE DEWPOINT DEPRESSION VALUES WITHIN THE BL AND A LAYER
OF MID LEVEL DRYING. CAPE VALUES SHOULD REMAIN VERY LIMITED DUE TO
THE LLVL DRY CONDITIONS AND SHALLOW MID LEVEL LAPSE RATES. BASED ON
THE LIMITED INSTABILITY AND LACK OF FORCING...I WILL KEEP CONDITIONS
DRY EAST OF THE MTNS AND ONLY INDICATE SCHC ACROSS THE MTNS.
TEMPERATURES MAY RANGE AROUND 1 TO 2 DEGREE BELOW NORMAL.

TUESDAY AND WEDNESDAY...BOTH THE GFS AND ECMWF INDICATE THAT THE
CENTER OF A 591DM 500MB LEVEL HIGH WILL BUILD OVER THE REGION. SFC
RIDGING WILL LIKELY BROADEN AND WEAKEN DURING THE PERIOD. FORECAST
SOUNDINGS CONTINUE TO FEATURE DEEP DRY AIR AND LITTLE TO NO VALUES
OF CAPE. I WILL KEEP POPS LIMITED TO A SCHC ACROSS THE WESTERN NC
MTNS ON TUESDAY...NO COVERAGE EAST. ON WEDNESDAY...CONVECTION CHC
WILL DECREASE FROM TUESDAY WITH THE MID RIDGING PEAKING OVERHEAD.
NORMAL TEMPERATURES ON TUESDAY WITH A RISE 3 TO 4 DEGREES ABOVE
NORMAL ON WEDNESDAY.

&&

.AVIATION /08Z THURSDAY THROUGH MONDAY/...
AT KCLT...THE TDWR SHOWS THAT THE BACK DOOR COLD FRONT HAS CROSSED
THE AIRFIELD. THIS WILL KEEP ANY NOCTURNAL SHOWER ACTIVITY BACK
ACROSS THE FOOTHILLS AND THE NRN UPSTATE. SCT TO BKN CLOUDS BETWEEN
4 TO 6 KFT SHOULD PERSIST THROUGH THE NIGHT. WINDS WILL BE DUE EAST
FOR A FEW HOURS...BUT THEY WILL VEER TO NE WITH TIME.

ELSEWHERE...A WEAK BACK DOOR COLD FRONT WILL SLOWLY PUSH SOUTHWEST
ACROSS THE REGION EARLY THIS MORNING. IT/S ALREADY THROUGH
KHKY...BUT IT WILL TAKE UNTIL SUNRISE BEFORE CROSSING THE UPSTATE
SITES. SCATTERED SHOWERS AND A FEW TSTMS WILL FIRE ALONG AND AHEAD
OF THE BNDRY AND VCSH HAVE BEEN ADDED OVER THE UPSTATE AND AT KAVL.
SCT TO BKN CIGS IN THE 4 TO 6 KFT RANGE WILL CONTINUE OVER THE FA
THROUGH THE NIGHT. WINDS WILL BE OUT OF THE NE MOST OF THE PERIOD.

OUTLOOK...GENERALLY DRY CONDITIONS ARE EXPECTED THROUGH MONDAY.
HOWEVER...ISOLATED AFTERNOON TSTMS WILL DEVELOP OVER THE MTNS EACH
DAY...WHICH COULD HAVE SOME AFFECT ON OPERATIONS AT KAVL.
