AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
251 PM EDT TUE MAY 22 2012

.SYNOPSIS...
AN UPPER LOW PRESSURE TROUGH WILL SLOWLY MOVE THROUGH THE REGION
TONIGHT INTO WEDNESDAY. HIGH PRESSURE WILL BUILD OVER THE AREA FOR
UNSEASONABLY WARM TEMPERATURES AND MOSTLY DRY WEATHER THURSDAY
THROUGH THE WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AS OF 220 PM...GOOD COVERAGE SEEN ON THE NEXRAD COMP WITH MOST OF
THE ACTIVITY ACROSS THE NC/GA MTNS REMAINING RELATIVELY LIGHT FOR
NOW. THERE ARE AREAS OF DIFFERENTIAL HEATING COMBINING WITH THE
UPPER FORCING THAT HAS PRODUCED DEEP CONVECTION ACROSS THE
UPSTATE...BUT NOTHING WARRANTING A STATEMENT/WARNING YET. EXPECT THIS
ACTIVITY TO CONTINUE THROUGH SUNSET WITH STRONGER STORMS
DEVELOPING...PERHAPS A MULTICELL CLUSTER COMING TOGETHER ACROSS THE
SC/NC PIEDMONT AROUND 23Z ALIGNED WITH LEADING EDGE OF THE ULVL
TROF.

OVERNIGHT...THE TROF STRENGTH REMAINS STEADY STATE WITH THE BEST
ENERGY AND DPVA DISPLACED SOUTH OF THE CWFA. HOWEVER...THERE WILL BE
ENOUGH LIFT AND SOME MEASURE OF ELCAPE AND MLVL LAPSE RATES FOR THE
CONTINUATION OF ISOL/SCT -SHRA/TSTMS. DONT ANTICIPATE A FLOODING
CONCERN...BUT THERE IS THE POTENTIAL FOR SOME STORMS TO REDEVELOP
OVER THE SAME AREAS AND IF THEY ARE OVER THE LOW FFG ZONES...THEN
MINOR FLOODING COULD BE PRODUCED. MIN TEMPS WILL REMAIN A FEW
DEGREES F ABOVE NORMAL WITH THE DEBRIS CLOUD COVER. ALSO...PATCHY
DENSE FOG WILL BE FAVORED ACROSS THE MTN VALLEYS.

WEDNESDAY...HEIGHTS WILL BEGIN TO RISE...HOWEVER AN OVERALL BROAD
TROF WILL ENCOMPASS THE ENTIRE SE REGION. MODEL SOUNDINGS SHOW
ENOUGH SBCAPE DEVELOPING...ESP ACROSS THE SOUTH AND EAST FOR SOME
STRONGER CONVECTION. DEEP SHEAR WILL BE VERY LOW AS THE UPPER LOW
BECOMES LESS DEFINED. HOWEVER...AT THE SFC THERE WILL BE WEAK LOW
PRESSURE CENTERED ACROSS ERN GA AND THE WRN UPSTATE...SO A NATURAL
CONVERGENCE ZONE WILL DEVELOP NORTH AND TO THE WEST OF THIS FEATURE.
THIS WILL BE THE AREA ADVERTISED FOR HIGHER CHANCE POPS...ESP ACROSS
THE NRN NC MTN AND FTHILLS. MAX TEMPS WILL BE A FEW DEGREES ABOVE
NORMAL SOUTH AND A FEW DEGREES BELOW NORMAL NORTH AS HIGHER CLOUD
COVER WILL LIMIT INSOLATION FOR A GOOD PART OF THE DAY ACROSS MOST
OF NC.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 230 PM TUESDAY...USED A GENERAL GFS/NAM MODEL BLEND FOR
THU-FRI TIMEFRAME. EXPECT POPS TO TAPER OFF TO SLIGHT CHC WED EVE
WITH COOLING. THE 500 MB LOW WILL FILL AND LIFT NE AS AN OPEN WAVE
WED NIGHT-THU WITH UPPER LEVEL DIFLUENT FLOW OVER THE AREA THU. ALSO
EXPECT INCRSNG LOW LEVEL S-SE FLOW TO BRING SOME MOISTURE OFF THE
ATLANTIC UP OVER THE AREA. LOOK FOR A CHC OF MTN TSTMS TO SPREAD OUT
ACROSS MUCH OF THE NC PIEDMONT THU AFTN...WITH ISOLD COVERAGE
UPSTATE SC AND NE GA. TEMPS SHOULD WARM ABOUT A CATEGORY ABOVE AVG.
UPPER WAVE MOVES NE OF THE AREA THU NIGHT WITH A RIDGE BUILDING IN
BEHIND IT. UPPER RIDGE CONTINUES TO BUILD OVER THE REGION FRI WHILE
A SFC RIDGE PUSHES DOWN OVER THE AREA FROM THE NE. LOW LEVEL E FLOW
COULD BRING ENOUGH ATLANTIC MOISTURE OFF THE E COAST...COMBINED WITH
WEAK UPSLOPE FLOW AND AFTN HEATING...FOR SLIGHT CHC TSTMS OVER THE
MTNS. TEMPS WILL WARM ANOTHER CAT ABOVE THU READINGS.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
AS OF 230 PM TUESDAY...THE LATEST MEDIUM RANGE MODELS CONTINUE TO
INDICATE THAT THE LARGE H5 HIGH WILL BUILD OVER THE MISSISSIPPI
VALLEY ON FRIDAY AND MIGRATES EAST ACROSS THE EASTERN CONUS THROUGH
THE WEEKEND. THEREFORE...EXPECT HIGH TEMPERATURES WARMING INTO THE
UPPER 80S FRIDAY AND REACHING THE LOW 90S ON SATURDAY OVER THE
PIEDMONT. WARMING TEMPERATURES ALOFT IN THE RIDGE WILL PROVIDE A
DEGREE OF CAPPING FOR CONVECTION...BUT A COMBINATION OF UPSLOPE FLOW
DUE TO PREDOMINANT SE TO E FLOW AND ELEVATED DIURNAL INSTABILITY MAY
SUPPORT THE DEVELOPMENT OF AFTERNOON ISOLATED/SCATTERED
THUNDERSTORMS ALONG THE BLUE RIDGE MOUNTAINS FRI THROUGH SAT. SO
HAVE KEPT SLIGHT CHANCE POPS THERE WITH DRY ELSEWHERE.

SUNDAY THROUGH TUESDAY...CONFIDENCE IS LOW AS THE MODELS SHOW
DIFFERENT SOLUTIONS FOR HANDLING THE TROPICAL FEATURE OVER THE
SOUTHEAST. THE GFS INDICATES THAT A TROPICAL LOW OVER THE ATLANTIC
OCEAN APPROACHES THE SE COAST ON SUNDAY AND CROSSES NORTHERN FL ON
MONDAY WHILE THE ECMWF HAS THE LOW LINGERING OFF THE SE COAST
THROUGH THE PERIOD. GIVEN THE UNCERTAINTY OF THE TRACK/INTENSITY OF
THE LOW...WILL CARRY SLIGHT CHANCE POPS OVER MUCH OF OUR CWA THROUGH
THE PERIOD. TEMPERATURES WILL REMAIN WELL ABOVE NORMALS.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
AT KCLT AND ELSEWHERE...EXPECT SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS THIS AFTERNOON AND INTO THE EVENING AFFECTING ALL
TERMINALS AT ONE TIME OR ANOTHER. THESE WRN STORMS WILL GENERALLY
DEVELOP EAST AS THE UPPER TROF DEEPENS AND PULLS NE. A DIURNAL IS
EXPECTED...BUT A FEW -SHRA/TSTMS WILL PERSIST. TOO LITTLE SPATIAL
CONFIDENCE TO ADVERTISE VCSH/VCTS AT ANY TAF SITE AFT 02Z. THERE
COULD BE SOME PATCHY DENSE FG AND PERHAPS SOME LINGERING LLVL STCU
IN THE MORNING. RIGHT NOW...KAVL LOOKS TO HAVE THE BEST CHANCE. SO
AN MVFR CIG/VSBY IS INCLUDED AT 11Z.

OUTLOOK...DIURNAL SHOWERS AND TSTMS SHOULD RE-DEVELOP AGAIN WED
AFTERNOON MOST AREAS. DIURNAL THUNDERSTORMS TOWARD THE END OF THE
WEEK ARE MORE LIKELY TO BE CONFINED TO THE MOUNTAINS AND FOOTHILLS.
EARLY MORNING RESTRICTIONS DUE TO FOG ARE A GOOD BET MAINLY IN THE
MOUNTAIN VALLEYS.
