AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1003 PM EDT WED JUN 13 2012

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

&&

.NEAR TERM /THROUGH THURSDAY/...
AS OF 950 PM WED...A FEW THUNDERSTORMS HAVE DEVELOPED ALONG THE LOW
LEVEL THETA E BOUNDARY PUSHING SWD ACROSS WRN NC. WHILE COVERAGE HAS
BEEN FAIRLY MINIMAL...THE STORMS HAVE BEEN STRONG TO SEVERE. THE
COVERAGE SHOULD DIMINISH FURTHER ACROSS THE NC FOOTHILLS AND
PIEDMONT OVERNIGHT...BUT SFC BASED CAPE VALUES ARE STILL IN EXCESS
OF 2000 J/KG ACROSS MUCH OF THE UPSTATE OF SC AND NE GA. WILL LIKELY
NEED SCT TSTM MENTION TO CONTINUE ALL NIGHT IN THE SRN HALF. THE
EASTERN SLOPES OF THE SOUTHERN MOUNTAINS COULD BE A SECONDARY MAXIMA
OF COVERAGE TOWARD DAYBREAK...AS LINGERING MOISTURE...INSTABILITY...
AND EASTERLY UPSLOPE FLOW COMBINE THERE.

UPPER HEIGHTS WILL GRADUALLY RISE ON THU AS A SIGNIFICANT RIDGE
BEGINS TO DEVELOP TO THE WEST. AT THE SURFACE...A LARGE SPRAWLING
HIGH TO THE NORTH OVER THE GREAT LAKES AND NEW ENGLAND WILL RIDGE
FARTHER SOUTHWARD ADVECTING LOWER DEWPOINTS INTO THE REGION. WEAKLY
UPSLOPE FLOW IN THE MOUNTAINS SHOULD BE ENOUGH FOR ISOLATED
AFTERNOON STORMS. USED A MOS BLEND FOR TEMPS.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
AS OF 130 PM WEDNESDAY...THE WRN RIDGE AXIS CONTINUES TO BUILD AND
STRENGTHEN THU NIGHT AND THIS WILL BE THE MAIN SYNOPTIC FEATURE OF
NOTE THROUGH THE SHORT RANGE. AT THE SFC...A FAIRLY STRONG AREA OF
HIGH PRESSURE WILL TRAVERSE EAST ACROSS ERN CANADA AND RIDGE DOWN
THE EAST COAST PRETTY QUICKLY THU NIGHT AND SHOULD REMAIN IN PLACE
THROUGH SAT.

THE PATTERN WILL ALLOW A CP AIR MASS TO BE REINFORCED AND MIXED INTO
THE REGION WITH SFC TD/S LOWERING INTO THE MID TO UPPER 50S BOTH FRI
AND SAT. THIS WILL OFFSET ANY CONVECTIVE CONCERNS AND LLVL MOISTURE
WILL BE HIGHLY LIMITED ANYWAY. THE BEST MOISTURE ADV WILL BE
CONCENTRATED ACROSS THE HIGHER TERRAIN...AND MAINLY FRI BEFORE THE
LOWER THETA/E ADV ENCOMPASSES THE MAJORITY OF THE CWFA ON SAT. OTHER
THAN ISOL AFTERNOON RAIN SHOWERS AND PERHAPS A GENERAL THUNDERSTORM
OR TWO ACROSS THE NC MTNS...THE FCST WILL REMAIN DRY THROUGH THE
PERIOD. MAX TEMPS WILL BE A COUPLE CATS BELOW NORMAL EACH DAY AS
SFC-H8 WINDS PERSIST NE/LY. MINS WILL ALSO BE A CAT OR SO BELOW
NORMAL EACH MORNING WITH LITTLE TO NO CLOUDINESS AND A THE P/GRAD
REMAINING TIGHT ALLOWING A MIX INTO RELATIVELY COOL AIR ABOVE THE
SFC.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
AS OF 100 PM WEDNESDAY...GOOD AGREEMENT IS HAD BTW THE OP MODELS
WITH THE EXT RANGE PATTERN THROUGH DAY 7. BASICALLY EXPECT THE MID
CONTINENT RIDGE AXIS TO SLOWLY SHIFT EAST AND IMPINGE UPON THE
ANOMALOUS ATL TROF...WHICH ITSELF WILL ADJUST IT/S LOCATION PER THE
PARENT REX BLOCK SITUATED ACROSS THE NRN ATL. ANYWAY...THIS PATTERN
WILL MAINTAIN A RIDGE OF SFC HIGH PRESSURE DOWN THE ATL COAST
THROUGH THE PERIOD TO SOME DEGREE. A LLVL THETA/E ANALYSIS SUGGESTS
THE AIR MASS WILL BE REINFORCED WITH RELATIVELY LOW TD/S. THE NE/LY
SFC WINDS WILL BEGIN TO VEER MON...BUT REMAIN RELATIVELY DRY AND
E/LY THROUGH TUE...BEFORE A MORE SE/LY FETCH IS REALIZED BY WED.
THIS WILL BE A DRY PATTERN FOR THE CWFA WITH DIURNAL RIDGE TOP
CONVERGENCE PROVIDING THE BEST FORCING FOR ANY -SHRA. EXPECT ONLY
FAIR WX CU NON/MTNS. POPS WERE MAINTAINED AT SLIGHT CHANCE ACROSS
THE HIGHER TERRAIN EACH AFTERNOON...WITH A SOMEWHAT LARGER COVERAGE
PATTERN ADVERTISED FOR WED. ALL IN ALL...A NICE STRETCH OF DAYS ARE
IN STORE WITH TD/S REMAINING IN THE MID TO UPPER 50S TO AROUND 60
BY LATE IN THE PERIOD. MAX TEMPS WILL BE IN THE LOW TO MID 80S
SUN/MON AND PERHAPS A COUPLE DEGREES WARMER TUE/WED AS THE UPPER
RIDGE STRENGTHENS ADVANCES TOWARD THE REGION.

&&

.AVIATION /02Z THURSDAY THROUGH MONDAY/...
AT KCLT...ISOLATED CONVECTION HAS DEVELOPED ALONG THE WEAK MOISTURE
BOUNDARY CREEPING SWD THROUGH THE NC PIEDMONT LATE THIS EVENING.
STILL THINK ANY TSTMS WILL MISS KCLT...BUT THIS WILL HAVE TO BE
MONITORED VERY CLOSELY FOR A POSSIBLE BRIEF TS MENTION IF ANY NEW
TOWERS DEVELOP. OTHERWISE...EXPECT MAINLY SCT CUMULUS OR
STRATOCUMULUS THROUGH THE PERIOD ON THE PERSISTENT NE FLOW. WINDS
SHOULD BE GENERALLY LESS THAN 10 KT THROUGH THE PERIOD. A FEW GUSTS
INTO THE MID TEENS WILL BE POSSIBLE AT TIMES...ESPECIALLY THU
MORNING.

ELSEWHERE...WITH A WEAK PASSING UPPER VORT LOBE AND A BOUNDARY
BACKDOORING INTO THE REGION FROM THE N TONIGHT...ISOLD TO SCT
CONVECTIVE COVERAGE COULD PERSIST AROUND THE TERMINAL FORECAST AREA.
THE NEXT ROUND ACROSS WRN NC HAS MISSED KHKY...AND NOTHING IS
THREATENING THE UPSTATE SITES OR KAVL LATE THIS EVENING...SO WILL
RIDE WITH NO FURTHER TSTM MENTION AT PRESENT. OTHERWISE...VFR CIGS
ARE LIKELY THROUGH THE PERIOD WITH MOISTURE PERSISTING ON NE FLOW.
EXPECT NE SFC WINDS AT LESS THAN 10 KT THROUGH THE PERIOD...EXCEPT
LIGHT TONIGHT AT KAVL BECOMING SE ON THU. KAVL COULD ALSO SEE MVFR
VSBY IN FOG AT TIMES OVERNIGHT.

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.
