AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
142 PM EDT SAT JUN 11 2011

.SYNOPSIS...
A WEAK RIDGE OF HIGH PRESSURE WILL PERSIST ACROSS THE REGION TODAY.
A COLD FRONT WILL APPROACH THE AREA FROM THE NORTHWEST ON SUNDAY AND
MOVE SOUTH OF THE REGION INTO MONDAY. HIGH PRESSURE WILL BUILD
SOUTHWARD INTO THE AREA BEHIND THE FRONT THROUGH THE MIDDLE OF NEXT
WEEK...BRINGING SLIGHTLY COOLER TEMPERATURES.

&&

.NEAR TERM /THROUGH TONIGHT/...
AT 1130 AM...LATEST VISIBLE SATELLITE IMAGES SHOW AN EXPANDING AREA
OF MID LEVEL CLOUDS ON THE EAST SIDE OF THE MTNS WITH CU OVER THE
RIDGES. MESOSCALE ANALYSIS INDICATES WEAK CIN ACROSS THE
CWA...ESPECIALLY ACROSS THE NC PIEDMONT. MID LEVEL CLOUDS MAY SLOW
DESTABILIZATION SLIGHTLY. AS THE CASE THE PAST SEVERAL
DAYS...CONVECTION SHOULD INITIATE OVER THE RIDGES NEAR THE EAST
FACING SLOPES EARLY THIS AFTERNOON. SHRA/TSRA SHOULD DRIFT EAST
DURING THE LATE AFTERNOON AND EVENING. I WILL INCREASE POPS ACROSS
THE MTNS...WITH LIKELY ACROSS THE RIDGES. IT APPEARS THAT CHC POPS
WILL VERIFY ACROSS THE FOOTHILLS AND PIEDMONT. HIGH TEMPERATURES
LOOK ON TRACK WITH U80S ACROSS THE MTNS TO L90S EAST.

FORECAST SOUNDINGS AND SREF GUIDANCE INDICATED THAT CAPES WILL RANGE
BETWEEN 1000 TO 2000 J/KG. DCAPE VALUES MAY RANGE AROUND 1000 J/KG.
FZL SHOULD RANGE AROUND 13 KFT...PLACING THE 55 DBZ CORE HEIGHT
AROUND 24 KFT. PW SHOULD RANGE FROM 1.25 TO 1.5 INCHES WITH K-INDEX
VALUES IN THE MID 30S. STORM MOTIONS WILL REMAIN VERY
SLOW...INCREASING POTENTIAL FOR EXCESSIVE RAINFALL. SEVERAL STORMS
MAY PRODUCE SVR HAIL AND DAMAGING WIND GUSTS. WE WILL CONTINUE TO
MENTION IN THE HWO.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
AS OF 230 AM SATURDAY...THE UPPER LEVEL FLOW PATTERN WILL AMPLIFY
SUNDAY THROUGH MONDAY...WITH A STRONG RIDGE OF HIGH PRESSURE OVER
THE SRN PLAINS AND DEEP LOW PRESSURE ACROSS NEW ENGLAND. ON THE
STRENGTH OF NW FLOW BETWEEN THESE FEATURES...A COLD FRONT WILL
APPROACH FROM THE NW SUNDAY AFTERNOON. MOS POPS APPEARS TOO LOW
GIVEN THE INSTABILITY AND BOUNDARY LAYER MOISTURE AHEAD OF THE
APPROACHING FRONT...SO WILL FEATURE POPS IN THE SOLID CHANCE RANGE
LATE SUNDAY.

THE BOUNDARY WILL SETTLE SOUTH OF THE REGION THROUGH MONDAY. A
FAIRLY POTENT SHORTWAVE IS INDICATED IN THE CONTINUED NW FLOW...PLUS
UPSTREAM MCS ACTIVITY COULD REACH THE AREA MONDAY OR MONDAY
NIGHT...BUT CONFIDENCE IS LOW ON THIS. WILL JUST ADVERTISE SLIGHT
CHANCES IN THE MOUNTAINS FOR NOW AS MOST OF THE AREA WILL BE DRYING
OUT BEHIND THE BOUNDARY. TEMPERATURES WILL REMAIN A FEW DEGREES
ABOVE NORMAL.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
AS OF 1230 PM SATURDAY...THE MEDIUM RANGE LOOKS LIKE A RETURN TO
SOMEWHAT ACTIVE WEATHER FOR THE LATTER HALF OF NEXT WEEK. ALTHOUGH
THE GUIDANCE SHOWS A SHORT WAVE RIDGE MOVING ACROSS THE AREA ON
WEDNESDAY AND WEDNESDAY NIGHT...A MEAN UPPER LONG WAVE TROF WILL
REMAIN OVER THE EASTERN PART OF THE COUNTRY. AFTER A DRY TUESDAY
NIGHT...DIURNAL CONVECTION WILL BE THE RULE ON WEDNESDAY. THE MAIN
FEATURE OF INTEREST HERE IS THE NEXT UPPER LOW DROPPING DOWN ACROSS
THE MIDWEST ON THURSDAY. THIS IS EXPECTED TO BRING DEEPER MOISTURE
AND FORCING INTO THE AREA FROM THE WEST ON WEDNESDAY NIGHT. THIS MAY
MANIFEST ITSELF AS A WARM FRONT OF SORTS MOVING THROUGH THURSDAY
MORNING EARLY IN THE DAY WITH SCATTERED SHOWERS AND STORMS. A COLD
FRONT IS EXPECTED TO DROP INTO THE FCST AREA ON THURSDAY AND THEN
SHOULD STALL ACROSS THE AREA FOR FRIDAY AND SATURDAY. SO...THURSDAY
AND THURSDAY EVENING COULD HAVE A SHOWER OR STORM AT ANY TIME.
SUSPECT THAT COVERAGE WILL BE NUMEROUS TO WIDESPREAD WHEN ALL IS
SAID AND DONE...BUT THE POP WILL BE LIMITED TO CHANCE FOR THE TIME
BEING. THE PRESENCE OF THE SURFACE BOUNDARY SHOULD GIVE US A DECENT
CHANCE FOR MORE PRECIP FRIDAY AND SATURDAY...BUT IT WILL BE
MODULATED BY THE DIURNAL CYCLE. TEMPS GENERALLY HAVE BEEN NUDGED
DOWNWARD A FEW DEGREES OWING TO MORE CLOUD COVER ACROSS THE REGION.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
AT KCLT AND ELSEWHERE...AT 1730Z...DEEP CONVECTION ACROSS THE
FORECAST AREA WAS SOLIDLY TIED TO THE RIDGES...WITH A SLOW DRIFT
EAST. DEEP CONVECTION WILL CONTINUE TO INCREASE ACROSS THE MTNS THIS
AFTERNOON...SPREADING INTO THE FOOTHILLS AND PIEDMONT DURING THE
LATE AFTERNOON AND EVENING. DEEP MOISTURE AND LINGERING INSTABILITY
MAY SUPPORT SHRA/TSRA WELL INTO THE EVENING...COVERAGE SHOULD BEGIN
TO DECREASE AROUND 2Z. OVERNIGHT...DEBRIS CLOUDS AND LIGHT SW WINDS
REMAIN ACROSS THE FORECAST AREA. PERSISTENCE AND MODEL CONSENSUS
FAVORS KEEPING THE TAFS P6SM OVERNIGHT. A COLD FRONT WILL APPROACH
THE SOUTHERN APPALACHIANS SUNDAY MORNING. THE ASSOCIATED WIND SHIFT
AND CONVECTION IS FORECAST TO REMAIN WEST OF THE TAFS BEFORE 18Z.

OUTLOOK...A COLD FRONT WILL MOVE IN FROM THE NORTHWEST SUNDAY...WITH
RESTRICTIONS ACCOMPANYING CONVECTION. DRIER HIGH PRESSURE WILL BUILD
IN FROM THE NORTH EARLY NEXT WEEK.
