Area forecast discussion, Apr 17, 7:57 PM EDT, 1 hour 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
757 PM EDT TUE APR 17 2012

.SYNOPSIS...
MOISTURE WILL SPREAD NORTHEAST AS A FRONT DRIFTS INTO THE WESTERN
CAROLINAS AND NORTHEAST GEORGIA. THIS FRONT WILL LINGER IN THE AREA
BRINGING MUCH NEEDED RAIN THROUGH WEDNESDAY. THE FRONT WILL
DEPART...AND WEAK HIGH PRESSURE WILL MOVE ACROSS THE AREA ON
THURSDAY AND FRIDAY. ANOTHER FRONT WILL ARRIVE ON SATURDAY. LOW
PRESSURE DEVELOPING ON THE FRONT WILL PASS NEAR THE AREA ON SUNDAY.
DRYING WILL OCCUR BEHIND THE DEPARTING LOW ON MONDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AS OF 750 PM...NUMEROUS TS/SHRA CONTINUE OVER THE MTNS WITH
CONVECTION DEVELOPING OVER NE GA...THE WRN UPSTATE AND THE YADKIN
RIVER VALLEY. EXPECT CONVECTION TO FILL IN THIS EVENING AS BOUNDARY
SAGS SOUTH ACROSS THE AREA PROVIDING A TRIGGER FOR THE INSTABILITY
IN PLACE OVER THE AREA. CONVECTION ENDS LATER THIS EVENING...BUT
SHRA INCREASE FROM WEST TO EAST AS LIFT AND DEEP MOISTURE RETURN
AHEAD OF THE STRONG UPPER LEVEL SYSTEM. ISOLATED SVR STORMS STILL
EXPECTED THIS EVENING WITH THE GOOD INSTABILITY AND DECENT EFFECTIVE
SHEAR. MADE MANY ADJUSTMENTS FOR CURRENT CONDITIONS THIS EVENING
WITH ONLY MINOR CHANGES AFTER MIDNIGHT BASED ON LATEST GUIDANCE.

AS OF 425 PM...MOST CONVECTION REMAINS LIMITED TO THE NC AND NE GA
MTNS. A FEW CELLS HAVE DEVELOPED OVER THE SAV RIVER...AND CELLS MAY
FILL IN EARLY ACROSS NE GA AND THE WRN UPSTATE WHERE INSTABILITY IS
HIGHEST. CONVECTION SHUD THEN SPREAD/DEVELOP EASTWARD INTO THE ERN
UPSTATE AND NC FOOTHILLS/PIEDMONT. HAVE MODIFIED POPS TO SHOW THIS
TREND. ADJUSTED REST OF THE FIELDS FOR CURRENT CONDITIONS AS WELL.
EFFECTIVE SHEAR IS AROUND 35 KTS OVER THE MTNS AND WRN UPSTATE...
WHERE HIGHEST CAPES ARE AS WELL. EXPECT BEST CHC FOR ANY ADDITIONAL
SVR STORMS TO BE IN THESE LOCATIONS.

AS OF 200 PM...AS EXPECTED...THE COLD FRONT HAS STALLED ACRS ROUGHLY
THE I-85 CORRIDOR THIS AFTN...WITH CONVECTIVE CU DEVELOPING. THE
HIGH RES MODELS ARE IN DECENT AGREEMENT ON CONVECTION FIRING ALONG
THE HIGH TERRAIN (WHICH STARTED IN THE LAST HOUR)...THEN NEW
DEVELOPMENT INVOF THE FRONT AND ALSO ALONG OUTFLOW OFF THE BLUE
RIDGE LATER THIS AFTN THRU THIS EVENING. STILL A MARGINAL SEVERE
THREAT MAINLY ACRS THE UPSTATE AND NE GA WHERE INSTBY IS GREATEST.
FREEZING LEVELS WERE OBSERVED AROUND 12 KFT ON 12Z SNDGS WITH VERY
DRY MID-UPR LEVELS. SO FIRST GUESS CORE HEIGHTS OF 22.5 TO 23 KFT
FOR 55DBZ SEEMS GOOD FOR LARGE HAIL AND DAMAGING WINDS. EFFECTIVE
SHEAR ON THE SPC MESOANALYSIS PAGE BARELY 30 KTS...SO LIMITED
ORGANIZATIONAL POTENTIAL. WITH THAT SAID...SLIGHT RISK AREA STILL
LOOKS GOOD.

TONIGHT AND WEDNESDAY...AN AREA OF STRONG QG FORCING AND JET
DIVERGENCE WILL OVERSPREAD THE CWFA FROM THE WEST...MAXING OUT
AROUND 12Z WED. A LLVL WAVE IS PROGGED TO DEVELOP INVOF CENTRAL GULF
STATES...INCREASING A SELY LLVL FLOW ATOP A STRENGTHENING COLD AIR
DAMMING (CAD) WEDGE. THINGS LOOK LINED UP WELL FOR CATEGORICAL POPS
AND DECENT QPF LATE TONIGHT INTO WEDNESDAY MORNING. TAKING A BLEND
OF MODEL QPF AND HPC RESULTS IN GENERALLY 1.0 TO 1.5" OF RAIN THRU
WEDNESDAY AFTN. RAIN SHUD REALLY BEGIN TO TAPER OFF TOWARD END OF
AFTN AS FORCING SHIFTS EAST OF THE AREA. TEMPS ARE TRICKY WITH
CLOUDS AND PRECIP AND CAD. I TRIED BLENDING STRAIGHT NAM WITH BC MOS
GRIDS...WHICH MAY STILL BE TOO WARM ALONG AND SOUTH OF I-85. TEMPS
DROP INTO THE 50S OVERNIGHT AND ONLY RISE 5-8 DEGREES WEDNESDAY.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AT 130 PM TUESDAY...DEEPER MOISTURE AND WARM CONVEYOR BELT FLOW WILL
BE SHIFTING EAST ACRS THE CWFA WEDNESDAY NIGHT STEADILY DWINDLING
SHOWER CHANCES. CLOUDINESS SHOULD REMAIN CONSIDERABLE INTO THURSDAY
MORNING WITH LINGERING SFC WEDGE BUT MODEL TIMEHEIGHTS DEPICT ENUF
MIXING TO ALLOW SUNSHINE TO RETURN WARMING TEMPERATURES TO A FEW
DEGREES ABOVE THE MID-APRIL CLIMO IN THE AFTERNOON. BROADENING
RETURN FLOW AND THE ONSET ON GULF TAP IS EXPECTED FOR FRIDAY AS MAX
TEMPERATURES ARE SLATED TO BE 6-8 DEG F ABOVE CLIMO. LACK OF
INHIBITION AND DESTABILIZING ATMOSPHERE SHOULD BE ABLE TO PROMOTE
DIURNAL TSTM ACTIVITY...ESPECIALLY ACRS THE MTNS.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AT 1105 AM TUESDAY...THE POTENTIAL REMAINS FOR A PERIOD OF ACTIVE WX
SATURDAY INTO SUNDAY FEATURING PROGRESSIVE UPPER HEIGHT FALLS ATOP
THE SE CONUS AND AN INCREASE IN DEEP LAYERED FORCING DOWNSTREAM OF
L/WV TROUGH AXIS AND GULF COAST CLOSED UPPER LOW. ATTENDANT SFC BNDRY
WILL ALSO BE SAGGING SE INTO THE CWFA. IN CONCERT WITH MODERATE
MOISTURE TRANSPORT FROM THE GULF...DEEP CONVECTIVE ACTIVITY SHOULD
BE NUMEROUS AND THERE IS THE POTENTIAL FOR AREAS OF HEAVY RAIN TO
FALL.

THE LATEST MEDIUM RANGE MODELS ABSORB CLOSED UPPER LOW INTO THE MEAN
FLOW BY MONDAY AND PATTERN PROGRESSION SHOULD TRANSLATE SFC FRONT TO
THE COAST. IF THE 17/00 UTC RUN OF THE ECMWF IS IN THE BALLPARK...A
PERIOD OF BLUSTERY AND COOLER CONDITIONS WITH WRAP-AROUND SHOWER
CHANCES SHOULD EXIST ON MONDAY. IT REMAINS TO BE SEEN HOW QUICKLY
EASTERN CONUS L/WV TROUGH LIFTS OUT BY THE END OF THE PERIOD...BUT
AT THIS POINT...AN EFFECTIVELY DRY FCST AND BELOW NORMAL
TEMPERATURES ARE ON TAP.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...CONVECTION HAS BEEN HELD AT BAY TO THE NORTH AND EAST OF
THE AIR FIELD. OUTFLOW BOUNDARY/COLD FRONT MOVING ACROSS THE SITE
ATTM SHIFTING WIND TO THE ENE. STILL EXPECT SOME CONVECTION TO MOVE
NEAR THE SITE AS THE BOUNDARY MOVES SOUTH AND PROVIDES A TRIGGER TO
ACT ON THE INSTABILITY IN PLACE. TSRA CHC WILL END LATE THIS EVENING
BUT SHRA CHC INCREASES AS LIFT AND DEEP MOISTURE MOVE IN AHEAD OF A
STRONG UPPER SYSTEM. THIS SHUD LEAD TO MVFR RESTRICTIONS BY
DAYBREAK. NELY WINDS WILL CONTINUE OVERNIGHT. MVFR EXPECTED THRU THE
DAY WITH SHRA CONTINUING...WITH SOME IMPROVEMENT POSSIBLE TOWARD THE
END OF THE PERIOD AS SHRA DIMINISH. NELY WIND CONTINUES THRU THE DAY
WITH GUSTS POSSIBLE WITH MIXING IN THE MORNING.

ELSEWHERE...TSRA CHC CONTINUES/INCREASES THRU THE EVENING BEFORE
DIMINISHING AFTER MIDNIGHT. RESTRICTIONS THIS EVENING WILL BE FROM
ANY CELLS MOVING OVER AIR FIELDS. WIDESPREAD SHRA WILL DEVELOP
OVERNIGHT AS LIFT AND DEEP MOISTURE MOVE IN AHEAD OF A STRONG UPPER
SYSTEM. THIS SHUD LEAD TO MVFR THEN IFR RESTRICTIONS BY DAYBREAK.
CONDITIONS IMPROVE TO MVFR BY MID-MORNING WITH GUSTY WINDS OUTSIDE
OF THE MTNS. HIGHER MVFR EXPECTED BY LATE AFTERNOON AS SHRA DIMINISH
FROM WEST TO EAST AND GUSTS COME TO AN END.

OUTLOOK...A LINGERING MOIST BOUNDARY LAYER WILL LIKELY CREATE A
RETURN TO IFR RESTRICTIONS WED NIGHT BEFORE DRYING BEGINS IN EARNEST
THU. EXPECT MAINLY VFR CONDITIONS THROUGH FRI...EXCEPT FOR POSSIBLE
EARLY MORNING FOG. ANOTHER COLD FRONT WILL LIKELY BRING
PRECIPITATION AND RESTRICTIONS BACK INTO THE AREA OVER THE WEEKEND.
