AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
444 PM EDT SUN JUN 12 2011

.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA FROM THE NORTHWEST TONIGHT AND MOVE
SOUTH OF THE REGION THROUGH MONDAY MORNING. HIGH PRESSURE AND
SLIGHTLY COOLER WEATHER WILL SET UP BEHIND THE FRONT THROUGH MID
WEEK. A WARM FRONT WILL RETURN LATE IN THE WEEK...WITH ANOTHER COLD
FRONT ARRIVING BY NEXT WEEKEND.

&&

.NEAR TERM /THROUGH MONDAY/...
AT 430 PM...LINE OF SEVERE THUNDERSTORMS DEVELOPING ALONG THE
FOOTHILLS AND WILL PUSH SOUTH AN EAST ACROSS THE CWFA THIS AFTERNOON
AND EARLY EVENING. ISOLATED TO SCT STORMS WILL TRAIL THE LINE...BUT
MAIN SVR THREAT WILL BE WITH THE LINE. HAVE GONE WITH LIKELY POP AND
SVR STORM WORDING WITH THE LINE AND MOVING IT ACROSS THE AREA. HEAVY
DOWNPOURS LOOK CERTAIN...BUT STORM MOTIONS WILL LIMIT THE FF
POTENTIAL...WE WILL MENTION HEAVY RAIN IN THE HWO.

TONIGHT...CONDITIONS WILL DRY FROM WEST TO EAST OVERNIGHT. IT
APPEARS THAT SKY COVER WILL BECOME MOSTLY CLEAR TO CLEAR LATE
TONIGHT. GIVEN CLEARING SKY COVER AND WEAK CAA LOW TEMPERATURES
SHOULD FALL SEVERAL DEGREES BELOW PERSISTENCE. CLEAR AND QUIET
CONDITIONS WILL REMAIN THROUGH MONDAY. COOLER MORNING TEMPS AND
LOWER THICKNESSES SHOULD RESULT IN HIGH TEMPERATURES 3 TO 4 DEGREES
COOLER THAN TODAY. FAVORING THE COOLER MET...I WILL FORECAST MID 80S
ACROSS THE MTN VALLEYS TO L90S EAST.

&&

.SHORT TERM /MONDAY NIGHT/...
AS OF 125 PM SUNDAY...THE UPPER PATTERN REMAINS COMPLICATED AND
UNSETTLED ACROSS THE ERN CONUS THROUGH THE SHORT RANGE. THE UPSTREAM
RIDGE SHOULD BEGIN TO BREAK DOWN AS A STRONG UPPER LOW BUILDS INTO
UPPER MIDWEST. THIS WILL ALLOW FOR A CONTINUED MAX/MIN VORT STREAM
ACROSS THE CWFA WHILE THE FLOW BECOMES MORE DIVERGENT ALOFT.

MODEL SOUNDINGS FOR TUE STILL SHOW LITTLE SBCAPE POTENTIAL OUTSIDE
THE MTNS...ESP THE NAM...BUT IN THIS ENVIRONMENT AND WEIGHTING
PERSISTENCE WILL COUNT ON ENOUGH INSTABILITY FOR TSTM DEVELOPMENT
TUE AFTNOON/EVE....HOWEVER STORMS DURING THIS TIME SHOULD REMAIN
RELATIVELY INNOCUOUS OR GENERAL IN NATURE. THE SREF PROBS ARE IN
THE 70 PERCENT RANGE FOR MEASURABLE PRECIP BEGINNING TUE EVENING AND
CONTINUING THROUGH WED. MAINLY ACROSS THE MTNS...BUT WORKING SOUTH
AS TIME PROGRESS. SO...POPS WERE BUMPED UP JUST A BIT TO MAINTAIN
THE SOLID CHANCE WORDAGE. A NEW FEATURE ADVERTISED IN THE OP MODELS
AND THE SREF IS THE DEVELOPMENT OF A TRIPLE POINT LOW ALONG AN
EXISTING BAROCLINIC ZONE BISECTING CWFA WED. THIS...ALONG WITH
INCREASING DYNAMICS AND DEEP LAYERED SHEAR COULD BE SETTING THE
STAGE FOR A ROUND OF ORGANIZED AND LONG LASTING SEVERE STORMS WED
AFTERNOON AND EVENING.

TEMPS TUE SHOULD REACH RIGHT AROUND 90 OUTSIDE THE MTNS...AND M80S
MTN VALLEYS. ON WED THERE WILL BE A SHARPER TEMP GRADIENT N/S...WITH
THE SRN ZONES REACHING NEAR 90 AND THE NRN ZONES PERHAPS A COUPLE
DEGREES BELOW NORMAL...WHILE THE MTN VALLEYS SHOULD SEE MAXES RIGHT
AROUND NORMAL.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
AS OF 1230 PM SUNDAY...THE MEDIUM RANGE LOOKS FAIRLY BUSY AND
UNSETTLED. THE PROGRESSION OF UPPER LOWS ALONG THE NRN TIER OF
STATES WILL EFFECTIVELY PUSH A BRANCH OF THE WESTERLIES DOWN ACROSS
THE MIDDLE OF THE COUNTRY. THIS WILL BRING A SURFACE FRONT INTO THE
REGION AND LEAVE IT LANGUISHING THROUGH THE PERIOD. THE MODELS SHOW
A PROGRESSION OF VORT CENTERS EASTWARD IN THE WNW FLOW ACROSS THE
REGION...BEGINNING WED NITE AND CONTINUING THRU THE WEEKEND...
SUGGESTING THE WESTERN CAROLINAS WILL BE IN THE MCS TRACK FOR THE
BETTER PART OF THE PERIOD. CONFIDENCE IN THE THUNDERSTORM CHANCE IS
GREATEST AT THE START OF THE PERIOD WHEN THE FRONT ARRIVES. THINK
JUST ABOUT EVERYONE WILL SEE A SHOWER OR STORM AT SOME POINT WED
NITE OR THURSDAY...BUT A LACK OF CONFIDENCE IN TIMING OF WHEN THE
LIKELIHOOD IS GREATEST WILL KEEP THE POP HELD DOWN TO THE CHANCE
RANGE. THE GOOD NEWS IS THAT TEMPS WILL BE MUCH CLOSER TO NORMAL AND
THAT WE SHOULD GET SOME BENEFICIAL RAIN.

&&

.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
AT KCLT AND ELSEWHERE...MODERATE INSTABILITY WILL REMAIN ACROSS THE
FORECAST AREA THIS AFTERNOON AND EVENING. SCT TO NUM TSRA WILL
DEVELOP ACROSS THE MTNS EARLY THIS AFTERNOON. THE AXIS OF COVERAGE
WILL SHIFT EAST OVER THE FOOTHILLS AND PIEDMONT LATE THIS AFTERNOON
AND EARLY THIS EVENING AS A COLD FRONT PUSHES ACROSS THE AREA. I
WILL INDICATE CB AT ALL TAF SITES WITH A TEMPO FOR TSRA LATE THIS
AFTERNOON AND EARLY THIS EVENING. TSRA SHOULD CLEAR THE FORECAST
AREA FROM WEST TO EAST THIS EVENING...ENDING BY MIDNIGHT. DRY AIR
AND LIGHT NNW WINDS WILL DEVELOP POST FRONT. HOWEVER...MVFR UPSLOPE
CLOUDS MAY DEVELOP ACROSS THE WEST FACING SLOPES OF THE MTNS. IT
APPEARS THAT KAVL WILL REMAIN TOO FAR EAST FOR A CEILING...I WILL
INDICATE FEW AT 030. AFTER SUNRISE...LIGHT NORTHWEST TO NORTH WINDS
WILL DEVELOP WITH MOSTLY CLEAR CONDITIONS.

OUTLOOK...DRIER HIGH PRESSURE WILL BUILD IN FROM THE NORTH MONDAY
AND TUESDAY...SO AFTN SHWRS/TSTMS WILL BE FEWER THAN LAST FEW DAYS.
FROM WEDNESDAY THRU REST OF THE WEEK...A GRADUAL INCREASE IN
MOISTURE WILL RESULT IN AN INCREASING CHC OF MAINLY DIURNAL
SHRA/TSRA AND MORNING VALLEY FOG.
