AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1038 PM EDT WED JUL 3 2013
.SYNOPSIS...
A DEEP UPPER LEVEL TROUGH WILL REMAIN IN PLACE OVER THE OHIO AND
TENNESSEE RIVER VALLEYS THROUGH THE END OF THE WORK WEEK. THE TROUGH
WILL GRADUALLY DISSIPATE OVER THE WEEKEND AS A BERMUDA HIGH BUILDS
IN FROM THE EAST AND REMAINS IN PLACE THROUGH EARLY NEXT WEEK.
&&
.NEAR TERM /THROUGH THURSDAY/...
AS OF 1030 PM...THERE IS CURRENTLY A LULL IN THE RAIN ACRS THE
WESTERN HALF OF THE CWFA WHERE THE HEAVY RAIN OCCURRED EARLIER THIS
EVENING. MEANWHILE...ANOTHER BAND OF MOD-HVY RAIN IS SETTING UP ON
THE EAST SIDE OF A DEEP MOISTURE PLUME...FROM THE NW NC PIEDMONT SSW
THRU THE CSRA AND MUCH OF SRN GA. THIS AREA OF PRECIP IS DRIFTING N
TOWARD THE BLUE RIDGE. THE 18Z GFS IS THE MOST BULLISH ON SUPPORTING
THE HEAVIER RAIN (MAINLY THRU UPR DIVERGENCE AND LLVL
UPSLOPE)...WHILE THE 00Z/04 NAM AND 12 ECMWF HAVE THE BEST FORCING
TO THE WEST OF THE CWFA. STILL EXPECT ANOTHER 1-2" OF ADDITIONAL
RAIN FOR THE NC MTNS OVERNIGHT WITH THIS BAND...WHICH MAY ELEVATE
LANDSLIDE THREAT. WILL FRESHEN WORDING IN THE HWO AND FFA.
OTHERWISE...NO SIGNIFICANT CHANGES.
PREVIOUS DISCUSSION...
AS OF MIDDAY WED...FOCUS FOR MOST WIDESPREAD HEAVY RAIN IN THE NEAR
TERM APPEARS TO BE THE SRN BLUE RIDGE AND SURROUNDING UPSLOPE FAVORED
AREAS. BEST MOISTURE TRANSPORT SEEN ACRS GA AND INTO THE SW NC MTNS
LATE TODAY AND TONIGHT WITH A CONNECTION TO THE ERN GULF OF MEXICO.
NONETHELESS DEEP SOUTHERLY FLOW AND MARITIME MOISTURE WILL BE PRESENT
ACROSS THE ENTIRE CWFA AND MODEL QPF CERTAINLY REFLECTS ENHANCEMENT
ALONG THE FULL STRETCH OF OUR PORTION OF THE BLUE RIDGE. EXCEPT FOR
SOME PASSING POCKETS OF UPPER VORT SHOWN OVER THE NC PIEDMONT
TODAY...THE MOST ACTIVE UPPER FEATURES ARE ALSO SEEN ON OUR WRN
PERIPHERY AS A JET STREAK STRENGTHENS IN THE MISSISSIPPI VALLEY EARLY
IN THE FCST PD. THIS FURTHER SUPPORTS ENHANCED QPF OVER OUR WRN
ZONES. PWAT VALUES REMAIN OVER 2 INCHES THIS AFTN AND
TONIGHT...BEGINNING TO DIMINISH EAST TONIGHT.
THE PIEDMONT APPEARS TO BE AT SOMEWHAT LESS OF A RISK OF WIDESPREAD
HEAVY RAIN WITH DEEP RH AND /BY ASSOCIATION/ PWATS THAT RETURN TO
MORE TYPICAL VALUES IN 1.5-1.75 INCH RANGE BY TOMORROW...WITH BERMUDA
HIGH MAKING INROADS ONCE AGAIN. THE DRIER CONDITIONS WILL PROMOTE
SOME CLEARING AND ALLOW SFC TEMPS TO WARM CLOSER TO NORMAL. BOTH
NAM/GFS SHOW ROBUST SBCAPES OF 1500 J/KG OR HIGHER DURING PEAK
HEATING THU...ALBEIT WITH WEAK SHEAR. STORM MOTION IS EXPECTED TO BE
ON THE SLOW SIDE WITH THE STRONGER FLOW OFF TO THE WEST...SO ISOLATED
FLASH FLOODING CANNOT BE RULED OUT. IN LIGHT OF THIS AND THE
ENVIRONMENT IN OUR WEST REMAINING PRIMED FOR MORE WIDESPREAD
FLOODING...WE WILL EXTEND THE FLASH FLOOD WATCH FOR THE WHOLE CWFA.
STRONG MIDLEVEL FLOW WILL CONTINUE OVER THE WEST THRU THE NEAR TERM
MEANING LLVL SHEAR VALUES WILL POSE A SMALL SEVERE THREAT IN ADDITION
TO THE FLOOD THREAT. INSTABILITY WILL BE LIMITED BY MEDIOCRE LAPSE
RATES WHICH WILL LIKELY KEEP STRONGER STORMS ISOLATED.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
AS OF 330 PM WEDNESDAY...GUIDANCE IN PRETTY GOOD AGREEMENT SHOWING A
WEAKENING IN THE UPPER TROF OVER THE CENTRAL CONUS ALLOWING THE
BERMUDA HIGH TO EXTEND ITS RIDGING WESTWARD OVER THE ERN SEABOARD.
THIS WILL HELP PUSH THE AREA OF DEEP SLY FLOW AND DEEP MOISTURE WEST
INTO THE TN VALLEY. HOWEVER...LOW LEVEL MOISTURE AND STRONG UPSLOPE
FLOW REMAIN OVER THE AREA FRI AND SAT. THAT SAID...DO EXPECT
COVERAGE TO BE HIGHER ON FRI AS THE RIDGE WILL NOT HAVE BUILT IN AS
FAR ALLOWING MORE MOISTURE AND INSTABILITY TO DEVELOP. GREATER
COVERAGE WILL BE OVER THE MTNS AND FOOTHILLS EACH DAY AS WELL GIVEN
THE UPSLOPE FLOW AND LESS RIDGE INTERACTION. SHUD BE A DIURNAL TREND
TO THE CONVECTION...BUT IT COULD LINGER THRU THE NITE EACH NITE.
THERE WILL BE QUITE A QPF GRADIENT ACROSS THE CWFA WITH RELATIVELY
LIGHT VALUES EAST AND HEAVIER VALUES WEST. COULD SEE THE NEED TO
EXTEND THE FLOOD WATCH OVER THE WRN CWFA FOR ANOTHER DAY...BUT WILL
WAIT UNTIL CLOSER TO THE EVENT TO MAKE THAT CALL.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
AS OF 335 AM TUESDAY...THE MEDIUM RANGE SHOWS A RETURN TO A MORE
NORMAL PATTERN AS THE BERMUDA RIDGE WEAKENS AND ELONGATES ACROSS THE
SRN CONUS AND A ZONAL FLOW DEVELOPS OVER THE NRN CONUS. AT THE
SFC...THE BERMUDA HIGH EXTENDS INTO THE SERN CONUS FROM THE ATLANTIC
THRU THE PERIOD. HOWEVER...THERE SHOULD BE ENUF S TO SWLY FLOW TO
KEEP LOW LEVEL MOISTURE ACROSS THE AREA. THIS SHOULD HELP PROVIDE
ENUF INSTABILITY TO OVERCOME THE RIDGING FOR SCT DIURNAL CONVECTION
TO DEVELOP EACH DAY. TEMPERATURES WILL ALSO RETURN TO A NORMAL LEVEL.
&&
.AVIATION /03Z THURSDAY THROUGH MONDAY/...
AT KCLT...THE MAIN AREA OF PRECIP HAS SET UP WELL WEST OF THE
TERMINAL...BUT SOME NWD-MOVING SHRA AND ISOLD TSRA WILL CONTINUE TO
KEEP A SMALL THREAT FOR KCLT INTO THE EVENING HOURS. WILL KEEP A
TEMPO FOR TSRA FOR 00-03Z. THEREAFTER...SHRA WILL CONTINUE ACRS THE
REGION WITH AN OVERALL LOWERING CIG/VSBY TREND THRU THURSDAY
MORNING. CONVECTION LIKELY TO INCREASE IN COVERAGE AGAIN WITH
HEATING DURING THE AFTN HOURS...SO WILL INCLUDE A PROB30. WINDS WILL
REMAIN S/SE THRU THE PERIOD...EXCEPT POSSIBLY WITH ANY SIGNIFICANT
TS OUTFLOWS.
ELSEWHERE...CIGS AND VSBY ACRS THE REGION RANGE FROM VFR TO
IFR...DUE TO AREAS OF +RA. OVERALL...PRECIP RATES AND COVERAGE SHUD
BEGIN TO DECREASE THRU THE EVENING INTO THE OVERNIGHT...BUT
LINGERING MOISTURE SHUD RESULT IN OVERALL DETERIORATING AVIATION
CONDITIONS. CONDITIONS WILL IMPROVE MOST EFFECTIVELY IN THE PIEDMONT
ON THU AS DRIER AIR WORKS IN THERE...HOWEVER INSTABILITY WILL BE
SUFFICIENT FOR TSRA TO DEVELOP BY EARLY AFTN IN THAT AREA IF NOT
ELSEWHERE. HAVE PROB30 FOR TS AT ALL SITES.
OUTLOOK...VERY MOIST AND UNSETTLED CONDITIONS WILL REMAIN OVER THE
REGION THROUGH INDEPENDENCE DAY. PERIODS OF SHRA/TSRA WILL OCCUR
BOTH DURING THE DAY AND OVERNIGHT. STRATUS AND FOG IS POSSIBLE EACH
DAY ACROSS THE REGION. SOME IMPROVEMENT IS EXPECTED THIS WEEKEND AS
A BERMUDA HIGH STRENGTHENS ACROSS THE REGION...YIELDING MAINLY
DIURNAL SHRA/TSRA. MORNING FOG WILL FAVOR THE MTN VALLEYS.
