AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
451 PM EDT THU JUL 4 2013

.SYNOPSIS...
A DEEP UPPER LEVEL TROUGH WILL REMAIN IN PLACE OVER THE MID
MISSISSIPPI RIVER VALLEY THROUGH FRIDAY NIGHT...BEFORE GRADUALLY
LIFTING EASTWARD OVER THE WEEKEND. HIGH PRESSURE WILL THEN BUILD
OVER THE SOUTHERN TIER OF THE UNITED STATES NEXT WEEK...WITH A
RETURN TO MORE TYPICAL SUMMERTIME CONDITIONS.

&&

.NEAR TERM /THROUGH FRIDAY/...
AS OF 445 PM...A QUICK UPDATE TO THE TEMP/DEWPT AND SKY GRIDS TO
MATCH UP WITH OBS. POPS/WX LOOK ON TRACK...SO LEFT AS IS FOR NOW.

AS OF 300 PM...NOT MUCH HAS CHANGED IN REGARDS TO THE FORECAST OVER
THE NEXT 24 HOURS.  SOUTHERLY FLOW WILL PROMOTE CONTINUED SHOWER AND
THUNDERSTORM ACTIVITY ACROSS THE ENTIRE REGION. HEAVY RAINFALL LOOKS
TO BE THE MAIN THREAT THROUGH THE PERIOD.  RAINFALL AMOUNTS
ADJACENT TO ANY THUNDERSTORMS COULD EXCEED 5 INCHES WHICH WILL ALLOW
FOR FLASH FLOODING CONDITIONS TO PERSIST.  THIS FLASH FLOODING
THREAT WILL MAINLY EXIST ACROSS THE HIGHER TERRAINS AND THE
FOOTHILLS DUE TO UPSLOPE FLOW AND MIGRATION OF MOISTURE AXIS TO THE
WEST.  OTHERWISE...INCREASING INSTABILITY ACROSS PORTIONS OF THE SC
UPSTATE AND THE NC PIEDMONT WILL ALLOW FOR SOME STRONG TO SEVERE
THUNDERSTORMS WITH DAMAGING WINDS...AND HEAVY RAINFALL BEING THE
MAIN THREATS.  DUE TO INCREASING FLOW ALOFT...AND BACKED SURFACE
WINDS...AN ISOLATED TORNADO CANNOT BE RULED OUT.  CONDITIONS WILL
NOT IMPROVE MUCH DURING THE OVERNIGHT HOURS AS PLUME OF MOISTURE
REMAINS NEARLY STATIONARY ACROSS THE WESTERN PART OF THE CWFA.
THUS...EXTENDED FLASH FLOOD WATCH THROUGH 00Z SATURDAY ACROSS ALL
ZONES WITH THE ONLY EXCEPTIONS BEING ACROSS PORTIONS OF THE NC
PIEDMONT.  TEMPERATURES OVERNIGHT WILL BE NEAR NORMAL FOR MOST SITES.

FOR FRIDAY...EXPECT MUCH OF THE SAME AS THURSDAY WITH CONTINUED
RAINFALL ACROSS THE WESTERN MOST PORTIONS OF THE REGION.
INSTABILITY WILL INCREASE YET AGAIN...HOWEVER CONVECTION SHOULD BE
ON MORE OF A DIURNAL TREND.  HIGH TEMPERATURES ON FRIDAY WILL BE
BELOW NORMAL AT ALL LOCATIONS.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
AS OF 230 PM THURSDAY...THE SLOWLY FILLING UPPER WAVE WILL LIFT NE
ACROSS IL/IN ON SAT AND THEN OH ON SUNDAY. UPPER LEVEL DYNAMICS IN
THE FORM OF WIND DIVERGENCE AND A TRAILING VORTICITY AXIS WILL CROSS
OUR FORECAST AREA ON SUNDAY. UNTIL THEN...PERSISTENT MOIST SRLY LOW
LEVEL FLOW WILL CONTINUE. WILL FOCUS LIKELY POPS IN THE MTNS...AND
TAPER DOWN TO MID RANGE CHANCE ACROSS THE PIEDMONT FOR SAT AFTN.
COVERAGE MAY REBOUND THROUGHOUT THE REGION A BIT ON SUNDAY WITH THE
PASSING UPPER SUPPORT. THE THREAT OF HEAVY RAIN AND ISOLATED FLASH
FLOODING WILL CONTINUE THROUGH THE WEEKEND.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 230 PM THURSDAY...A FLAT RIDGE WILL BUILD OVER THE SRN TIER OF
THE CONUS MON THROUGH WED. SFC HIGH PRES WILL DOMINATE EXCEPT FOR A
DEVELOPING LEE TROUGH OVER THE PIEDMONT. MID LEVEL DRYING IS
INDICATED...BUT LOW LEVELS WILL REMAIN MOIST THROUGH THE PERIOD. SFC
TO 850 MB FLOW WILL VEER MORE WESTERLY TO CURB PRECIPITATION CHANCES
AND PRODUCE MORE OF A DIURNAL TREND IN POPS. A COLD FRONT WILL
APPROACH THE AREA FROM THE NW ON THU. EXPECT MAX TEMPS TO RECOVER TO
NEAR SUMMERTIME NORMALS.

&&

.AVIATION /21Z THURSDAY THROUGH TUESDAY/...
AT KCLT...LOW END VFR CONDITIONS WILL PREVAIL THROUGH THE PERIOD
WITH THE ONLY EXCEPTIONS BEING IN PROXIMITY TO CONVECTION THIS
AFTERNOON.  SOUTHERLY FLOW CONTINUES TO PROMOTE INCREASING
INSTABILITY ACROSS THE NC PIEDMONT...THUS WENT WITH A TEMPO FOR TSRA
THROUGH 00Z.  BEYOND THAT...CARRIED MVFR CIGS FOR A FEW MORE HOURS
AS THE BOUNDARY LAYER REMAINS NEAR SATURATION.  OTHERWISE...RAISED
CIGS TO VFR LEVELS THROUGH THE REMAINDER OF THE TAF CYCLE.  WINDS
WILL REMAIN SOUTHERLY AND IN THE 8-10KT RANGE.

ELSEWHERE...EXPECTING WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY TO
CONTINUE THROUGH MUCH OF THE TAF PERIOD...ESPECIALLY ACROSS THE SC
SITES.  ADDED TEMPO GROUPS AT ALL SITES FOR MVFR TSRA THIS
AFTERNOON...THEN CARRIED MVFR CIGS THROUGH THE MORNING WITH EITHER
VCTS...SHRA...OR BOTH.  AS THE LOWER LEVELS CONTINUE TO MOISTEN
FURTHER THROUGHOUT THE EVENING...LOOKING FOR CIGS TO LOWER TO IFR
LEVELS AT ALL SITES.  WINDS WILL REMAIN SOUTHERLY AND AROUND
8-10KTS.

OUTLOOK...VERY MOIST AND UNSETTLED CONDITIONS WILL REMAIN OVER THE
REGION INTO SATURDAY...WITH PERIODS OF SHRA/TSRA. STRATUS AND FOG IS
POSSIBLE EACH DAY ACROSS THE REGION. GRADUAL IMPROVEMENT IS EXPECTED
FROM THE EAST THIS WEEKEND AS A BERMUDA HIGH STRENGTHENS ACROSS THE
REGION...YIELDING MAINLY DIURNAL SHRA/TSRA. MORNING FOG WILL FAVOR
THE MTN VALLEYS.
