Flash Flood and Flood in North Carolina, August 18 to 19, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
823 PM EDT TUE AUG 18 2015

.SYNOPSIS...
A WET PATTERN WILL PERSIST ACROSS THE SOUTHEAST AS DEEP MOISTURE
REMAINS IN PLACE THROUGH MID-WEEK. A WEAK FRONT WILL APPROACH THE
AREA ON THURSDAY BRINGING YET ANOTHER CHANCE OF WIDESPREAD SHOWERS
AND THUNDERSTORMS. MORE TYPICAL CHANCES OF PRECIPITATION ARE
EXPECTED INTO THE WEEKEND WITH ANOTHER FRONT POSSIBLY ARRIVING BY
NEXT MONDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AS OF 815 PM...SOME RATHER VIGOROUS CONVECTION HAS DEVELOPED ALONG
THE I-77 CORRIDOR IN THE PAST HOUR...WHERE TEMPS MANAGED TO WARM TO
AROUND 90 AFTER LATE DAY CLEARING. EVEN WITH THIS ACTIVITY...THE
SEVERE WEATHER THREAT IS LOW. MEANWHILE...STEERING CURRENTS ARE
PROVIDING A DECENT AMOUNT OF FORWARD MOMENTUM TO TODAY/S ACTIVITY...
SO THE LOCALLY EXCESSIVE RAINFALL THREAT SHOULD BE CONFINED TO AREAS
THAT MANAGE TO SEE TRAINING CELLS...MAINLY ACROSS THE URBAN CORRIDOR
EAST AND NORTH OF CHARLOTTE. LIKELY TO CATEGORICAL POPS WILL HANDLE
THE ONGOING ACTIVITY ACROSS THE EASTERN AND WESTERN ZONES. POPS WILL
THEN DROP OFF TO CHANCE BY MIDNIGHT IN MOST AREAS...AS IT DOES
APPEAR THAT THERE WILL BE AN OVERNIGHT LULL IN THIS MORE ORGANIZED
ACTIVITY.

AT 230 PM EDT TUESDAY...AN BROADENING UPPER TROUGH WILL BE OVER THE
CENTER OF THE NATION THROUGH WEDNESDAY...WHILE A WEAK UPPER RIDGE
WILL AMPLIFY SLIGHTLY OFF THE CAROLINA COAST. WEAK...CHANNELED
SHORTWAVE ENERGY AND SUBSTANTIAL MOISTURE FROM THE GULF WILL CROSS
THE SOUTHERN APPALACHIANS...SUPPORTING CONTINUED PRECIPITATION. LOW
LEVEL FLOW WILL VEER FROM S TO SW TONIGHT...REDUCING UPSLOPE FLOW
INTO THE BLUR RIDGE. MODEL TIME HEIGHTS SHOW MODEST INSTABILITY
PERSISTING OVERNIGHT...BUT THE BEST SUPPORT FOR CONVECTION WILL BE
DURING DAYTIME HEATING. WITH INSTABILITY RATHER LIMITED...SEVERE
WEATHER IS LESS OF A CONCERN THAN HEAVY LOCALLY HEAVY RAINFALL.
STEERING FLOW SHOULD KEEP CELLS MOVING HOWEVER. TEMPERATURES WILL
EXHIBIT A REDUCED DIURNAL RANGE DUE TO CLOUDS AND MOISTURE.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 200 PM EDT TUESDAY...THE SHORT TERM FCST PERIOD INITIALIZES
WEDNESDAY EVENING AMIDST CONTINUED SOUTHWEST FLOW ALOFT AHEAD
OF A PROGRESSIVE LONGWAVE TROF THAT WILL BE SLIDING THROUGH THE
MID/UPPER MISSISSIPPI RIVER VALLEY.  IN THE LOW LEVELS...GULF
MOISTURE ADVECTION IS EXPECTED TO REMAIN PREVALENT THUS YIELDING
CONTINUED DEEP MOISTURE IN THE PROFILES ACROSS MUCH OF THE
SOUTHEAST TO INCLUDE NORTHEAST GA AND THE WESTERN CAROLINAS.
NEAR TERM GUIDANCE IS IN FAIRLY GOOD AGREEMENT REGARDING MODEST
DESTABILIZATION LEADING TO SCATTERED/NUMEROUS CONVECTION AT
FCST INITIALIZATION.  THUS THE FCST FEATURES LIKELY POPS OVER
THE HIGH TERRAIN TAPERED TO SOLID CHANCES EAST OVER THE NC/SC
PIEDMONT BEFORE ALL POPS TAPER DOWN TO SLIGHT CHANCES BY MORNING.
CANNOT RULE OUT ANY HYDRO ISSUES OVER THE ALREADY IMPACTED AREAS ON
WEDNESDAY EVENING AS PREVIOUS ACCUMULATIONS WILL WORK TO INCREASE
ANTECEDENT CONDITIONS SUPPORTIVE OF ISOLATED FLASH FLOODING.

A COLD FRONT TIED TO THE ABOVE MENTIONED SYNOPTIC TROF IS PROGGED
TO SLIDE INTO THE NC HIGH TERRAIN LATE ON THURSDAY NIGHT.  AHEAD OF
SAID FRONT...THE ATMOSPHERE WILL DESTABILIZE WITH HEATING TO THE
POINT OF SUPPORTING AT LEAST SCATTERED CONVECTION OVER THE LOW
TERRAIN...WITH NUMEROUS SHOWERS AND THUNDERSTORMS POSSIBLE ALONG
THE BLUE RIDGE THEREFORE FCST POPS FEATURE SUCH ON THURSDAY.
PROFILES WILL CONTINUE TO BE MOIST WITH PWATS EXCEEDING 1-2 SDS
ABOVE NORMAL...WHICH COMBINED WITH UNIDIRECTIONAL SHEAR SUPPORTING
POSSIBLE TRAINING STORMS...COULD YIELD FURTHER ENHANCEMENT OF
ISOLATED FLASH FLOODING ISSUES.  THE FRONT ITSELF IS FCST TO SLIDE
THROUGH THE REGION OVERNIGHT INTO FRIDAY MORNING FINALLY CUTTING OFF
THE WARM MOIST SOUTHWESTERLY CONVEYOR BELT.  THAT SAID...LITTLE IF
ANY DRY AIR ADVECTION IS EXPECTED AS THE BOUNDARY WILL SLOW...AND
COULD STALL OVER OR JUST SOUTH OF THE FCST AREA THEREFORE CHANCE
POPS REMAIN IN THE FCST ON FRIDAY.  TEMPERATURES THROUGH THE
ENTIRE SHORT TERM PERIOD WILL GENERALLY REMAIN NEAR NORMAL WITH
SOME LOWER DEVIATION LIKELY THANKS TO PARTLY/MOSTLY CLOUDY SKIES
AND RAINFALL EACH DAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 230 PM EDT TUESDAY...THE EXTENDED PERIOD BEGINS FRIDAY
EVENING WITH A MID-LEVEL ANTICYCLONE OVER THE EASTERN GULF COAST
WITH AN ASSOCIATED RIDGE AXIS EXTENDING NORTHEAST OVER THE ATLANTIC
COASTAL PLAIN.  THE PRIMARY OR LONGWAVE STORM TRACK EXTENDS FROM THE
PACIFIC NORTHWEST TOWARDS THE HUDSON BAY...LEAVING MUCH OF THE CONUS
IN A FAIRLY ZONAL FLOW.  EMBEDDED IN THIS FLOW ARE SEVERAL
PERTURBATIONS...WITH THE MOST NOTABLE ONE ACROSS THE SOUTHERN
PLAINS. THE RESULTANT FLOW ALOFT OVER THE FORECAST AREA IS WEST-
SOUTHWESTERLY...AND AHEAD OF THE SOUTHERN PLAINS SHORTWAVE WILL BE
AT LEAST A COUPLE OF WEAK PULSES OF VORTICITY THAT TRAVERSE NEAR THE
AREA THROUGH SUNDAY.  BY SUNDAY EVENING THE SOUTHERN PLAINS WAVE
WILL BE APPROACHING THE SOUTHERN APPALACHIANS AND THE RESULTANT
TROUGH WILL BE AMPLIFIED BY MORE SUBSTANTIAL ENERGY ASSOCIATED WITH
A STRONG CLOSED LOW EMBEDDED IN THE LONGWAVE STORM TRACK ACROSS THE
UPPER MIDWEST.  THEREAFTER...THERE EXISTS SIGNIFICANT DIFFERENCES
BETWEEN THE GUIDANCE IN HOW THE CLOSED LOW EVOLVES AND WHETHER OR
NOT THE FORECAST AREA LIES TO THE EAST OF A LONGWAVE TROUGH AXIS
ALIGNED OVER THE LOWER MISSISSIPPI RIVER VALLEY OR SLIGHTLY TO THE
WEST OF A RESIDUAL TROUGH AXIS THAT EXTENDS FROM THE PIEDMONT TO THE
GULF OF MEXICO.  REGARDLESS...THERE IS CONSENSUS THAT A DEEP-LAYER
RIDGE WILL DEVELOP OVER THE INTERMOUNTAIN WEST BY TUESDAY OF NEXT
WEEK AND THAT SHOULD AT LEAST RESULT IN A GENERAL TROUGH PATTERN
OVER THE EASTERN CONUS.

AT THE SURFACE...A RESIDUAL FRONTAL BOUNDARY WILL LIE ACROSS THE
CENTRAL CAROLINAS FRIDAY EVENING AND WILL GRADUALLY BE SHUNTED SOUTH
TOWARDS THE GULF COASTAL PLAIN AS SURFACE HIGH PRESSURE BUILDS IN
ACROSS THE NORTHEAST AND NOSES DOWN THE BLUE RIDGE THROUGH SUNDAY
MORNING.  THE COLD FRONT ATTENDANT WITH THE UPPER MIDWEST CLOSED LOW
WILL APPROACH THE FORECAST AREA SUNDAY NIGHT INTO MONDAY MORNING
WITH A LARGE SURFACE HIGH OVER THE MIDWEST.  THE FRONT IS EXPECTED
TO PASS THROUGH THE AREA WITH HIGH PRESSURE CENTERED OVER THE
EASTERN GREAT LAKES BY MONDAY NIGHT. ONCE AGAIN HOWEVER...THE
GUIDANCE DIFFERENCES IN THE UPPER-LEVEL PATTERN RESULT IN DIFFERENT
SENSIBLE WEATHER IMPACTS FOR OUR AREA FOLLOWING THE FRONT ON TUESDAY
INTO WEDNESDAY.  GIVEN THE ANOMALOUS NATURE OF THE LONGWAVE TROUGH
SOLUTION BY THE ECMWF...OPTED FOR WHAT APPEARS TO BE A MORE
CLIMATOLOGICAL SOLUTION BY THE GFS...WHICH FAVORS A NORTHEASTERLY OR
EASTERLY LOW-LEVEL...UPSLOPE FLOW ACROSS THE AREA INSTEAD OF A FALL-
LIKE CLEANER FRONTAL PASSAGE AND BETTER NORTHWESTERLY FLOW AND DRY-
AIR ADVECTION BEHIND THE FRONT.  THE PREFERRED SOLUTION THEREFORE
MAINTAINS CHANCE POPS THROUGH THE END OF THE PERIOD...SLIGHTLY BELOW
NORMAL MAXIMUM TEMPERATURES...AND NEAR NORMAL MINIMUM TEMPERATURES.
WITH SLIGHTLY LESS AVAILABLE MOISTURE IN THE COLUMN AND A LACK OF
NOTABLE FORCING THROUGH THE PERIOD...6-HOUR AREAL-AVERAGED QPF
VALUES REMAIN LIGHT...THOUGH THE NORMAL THREAT FOR LOCALLY HEAVY
RAIN EACH DAY REMAINS.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...HEAVY RAIN SHOWERS S/SW OF THE TERMINAL MAY BRUSH THE
TERMINAL DURING THE NEXT HOUR OR SO...WITH TS/GUSTY WINDS POSSIBLE.
ONCE THIS PASSES THROUGH...ANOTHER AREA OF SHOWERS...CURRENTLY NEAR
THE GA/SC BORDER MAY MOVE ACROSS THE TERMINAL BY LATE IN THE
EVENING...SO ANOTHER ROUND OF TEMPO W/ SHRA IS ADVERTISED DURING
THAT TIME. OTHERWISE...CONFIDENCE IS BELOW AVERAGE AFTER ABOUT 06Z
IN TERMS OF IF/WHEN FOG/LOW STRATUS WILL FORM. SOME OF THE SHORT
TERM GUIDANCE SOURCES ACTUALLY DRY THE LOW LEVELS OUT A BIT...AS THE
LOW LEVEL FLOW TURNS TO THE W/SW. MEANWHILE...GUIDANCE IN GENERAL
DOES NOT SUPPORT MUCH IN THE WAY OF SIGNIFICANT FLT RESTRICTIONS.
NEVERTHELESS...CONSIDERING THE AMOUNT OF MOISTURE IN THE
ENVIRONMENT...OPTED TO INCLUDE A SCT008 MENTION TOWARD DAYBREAK.
WITH MOISTURE REMAINING ABOVE NORMAL...AND PERHAPS A LITTLE MORE IN
THE WAY OF INSTABILITY...AT LEAST SCT SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO DEVELOP AGAIN WED AFTERNOON.

ELSEWHERE...WEAKENING AREA OF SHOWERS AND ISOLATED TS WILL MOVE
ACROSS THE TERMINALS THIS EVENING...WARRANTING TEMPOS OVER THE NEXT
2-3 HOURS. AFTER THAT...IT APPEARS THAT THERE WILL BE A LULL IN
ORGANIZED SHOWER/THUNDERSTORM ACTIVITY...ALTHOUGH WITH THE
ATMOSPHERE REMAINING UNSEASONABLY MOIST...CANNOT RULE OUT A PASSING
SHOWER AT ANY TIME...THUS VCSH WAS CARRIED INTO THE MORNING HOURS AT
ALL SITES. OTHERWISE...CONFIDENCE IS BELOW AVERAGE AFTER ABOUT 06Z
IN TERMS OF IF/WHEN GOB/LOW STRATUS WILL FORM. SOME OF THE SHORT
TERM GUIDANCE SOURCES ACTUALLY DRY THE LOW LEVELS OUT A BIT...AS THE
LOW LEVEL FLOW TURNS TO THE W/SW. MEANWHILE...GUIDANCE IN GENERAL
DOES NOT SUPPORT MUCH IN THE WAY OF SIGNIFICANT FLT RESTRICTIONS.
THE ONLY EXCEPTION IS AT KAVL...BUT EVEN THERE CONFIDENCE WAS NOT
HIGH ENOUGH TO GO ANY LOWER THAN THE HIGH END OF IFR.
NEVERTHELESS...CONSIDERING THE AMOUNT OF MOISTURE IN THE
ENVIRONMENT...CANNOT RULE OUT FLT RESTRICTIONS...INCLUDING POSSIBLY
IFR CONDITIONS TOWARD DAYBREAK. WITH MOISTURE REMAINING ABOVE
NORMAL...AND PERHAPS A LITTLE MORE IN THE WAY OF INSTABILITY...AT
LEAST SCT SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP AGAIN WED
AFTERNOON.

OUTLOOK...MOISTURE IS EXPECTED TO HIGH FOR MUCH OF THE WEEK. ABOVE-
NORMAL CHANCES FOR MAINLY DIURNAL SHOWERS AND THUNDERSTORMS WILL
RESULT...WITH CONVECTIVE CHANCES LIKELY CONTINUING INTO THE
OVERNIGHT MOST DAYS. NOCTURNAL LOW STRATUS AND FOG WILL ALSO BE
POSSIBLE...ESP IN MTN VALLEYS AND IN LOCATIONS THAT SAW HEAVY
RAIN THE DAY BEFORE.
