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

.SYNOPSIS...
A RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE REGION TODAY AND BEGIN
TO WEAKEN BEFORE A COLD FRONT APPROACHES THE AREA SUNDAY. HIGH
PRESSURE WILL BUILD SOUTH ACROSS THE AREA BEHIND THE FRONT THROUGH THE
MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
2200 UTC UPDATE...WINDS HAVE BEEN UPDATED WITH A BLEND OF THE LATEST
MODEL GUIDANCE THROUGH SUNDAY. SKY COVER...GUSTS AND APPARENT
TEMPERATURES WERE UPDATED AS WELL.

AT 225 PM...LATEST VISIBLE SATELLITE IMAGES SHOWS EXTENSIVE
CONVECTIVE CLOUDS OVER THE RIDGES WITH SHALLOW CU FIELD EAST OF THE
MTNS. IN ADDITION...AN OLD OUTFLOW BOUNDARY WAS OVER MIDDLE
KY/TN...TREKKING SOUTHEAST. IT IS QUESTIONABLE IF THE OUTFLOW WILL
REACH THE CWA. TSRA SHOULD CONTINUE TO POPULATE THE MTN RIDGES THIS
AFTERNOON...SPREADING ACROSS THE VALLEYS DURING THE MID AND LATE
AFTERNOON WITH FURTHER DESTABILIZATION AND SUPPORT FROM LOCALLY
PRODUCED OUTFLOW BOUNDARIES. DEEP CONVECTION EAST OF THE MTNS SHOULD
BECOME COMMON DURING THE LATE AFTERNOON AS CIN BECOMES ZERO. AS THE
CASE LATE THIS WEEK...CONVECTION MAY SURVIVE A COUPLE OF HOURS PAST
MIDNIGHT TONIGHT. LOW TEMPERATURES ARE FORECAST TO RANGE FROM THE
L60S ACROSS THE MTN VALLEYS TO THE U60S EAST.

AT 18Z...MESOSCALE ANALYSIS INDICATED THAT CAPES RANGED BETWEEN 1500
TO 2500 J/KG. DCAPE VALUES MAY RANGE AROUND 1000 J/KG. FZL SHOULD
RANGE AROUND 13.5 KFT...PLACING THE 55 DBZ CORE HEIGHT AROUND 24.5
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.

SUNDAY...A COLD FRONT WILL APPROACH THE CWA FROM THE WEST THROUGH
THE MORNING...REACHING THE SOUTHERN APPALACHIANS DURING THE LATE
AFTERNOON AND EVENING. BEFORE THE FRONT ARRIVES...THE ENVIRONMENT
WILL BECOME MODERATELY UNSTABLE WITH WEAK CIN DURING THE AFTERNOON.
WEAK SHEAR AND GOOD INSTABILITY SHOULD SUPPORT MAINLY PULSE STORMS
FROM EARLY AFTERNOON UNTIL THE FRONT ARRIVES. AS THE FRONT
APPROACHES...CONVECTION MAY FORM INTO MULTICELLS WITH QUICKER STORM
MOTIONS. I WILL FORECAST HIGH CHC POPS BY LATE AFTERNOON. HIGH
TEMPERATURES WILL REMAIN NEAR 10 DEGREES ABOVE NORMAL.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
AS OF 200 PM SATURDAY...THE UPSTREAM FLOW BECOMES MORE AMPLIFIED
WITH A RATHER PRONOUNCED RIDGE AXIS REDEVELOPING ACROSS THE CENTRAL
MIDWEST. THE MODELS ARE STILL BRINGING IN A S/W ASSOCIATED WITH THE
NEW ENG LOW MON AFTERNOON AND EVENING. THE 12Z GFS IS THE STRONGEST
WITH THIS FEATURE AND THE DPVA FIELD...WHILE THE NAM AND SREF SHOW
ONLY MODEST SUPPORT. A TRICKY FORECAST FOR POPS ACROSS THE NC MTNS
AS THE LLVLS WILL BE EXPERIENCING AN INFLUX OF LOWER THEATA/E WHILE
A CA HIGH BUILDS OVER THE OH VALLEY. MODEL SOUNDINGS ACROSS THE MTNS
HAVE NEGLIGIBLE SBCAPE AND VERY LITTLE ELCAPE...WHILE CINS REMAIN IN
THE 300-400 J/KG. SO...WITH SUSPECT CONV INSTABILITY AND AN
UNFAVORABLE LLVL THERMAL STRUCTURE AND MINIMAL MOISTURE...THE GRIDS
WILL BE LEFT POP FREE EXCEPT ACROSS ELEVATIONS ABOVE 4KFT WHERE ISOL
TSTMS WILL POSSIBLE ASSOCIATED WITH MECHANICAL LIFT AND THE UPPER
ENERGY SUPPORT.

ON TUES...THE PATTERN BECOMES A LITTLE MORE SUPPRESSED AS THE
AFOREMENTIONED CA HIGH REINFORCES AND RIDGES DEEPER SOUTH ACROSS THE
CWFA. THE GFS IS ACTIVATING A WARM FRONT OFF TO THE WEST AND THIS
COULD SWING CLOSE ENOUGH TO THE MTNS FOR A LATE DAY CONVECTIVE
THREAT....HOWEVER THERE IS LITTLE LLVL RESPONSE SEEN ON THE MUCH
FURTHER NORTH NAM. SO...WILL KEEP THE GRIDS POP FREE FOR TUE. DEEP
LAYERED FLOW WILL BECOME STRONGER AND DEEP NW/LY AS WELL...WHICH
WILL ALSO HELP SUPPRESS CONV INITIATION THROUGH THE DAY. MAX AND
TEMPS THROUGH THE PERIOD WILL REMAIN A COUPLE CATS ABOVE
NORMAL...WITH A BIT COOLER CONDITIONS EXPECTED FOR TUE WITH THE
LOWER THETA/E AIR MIXING IN.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
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 /22Z 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.
