Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Charleston AFB, SC (KCHS), launched 12:00Z, 9.4 hours before the alert went out and 31 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
402 PM EDT TUE AUG 12 2014
.SYNOPSIS...
A COLD FRONT WILL APPROACH THE AREA LATE TONIGHT...THEN DRIFT
OVER THE AREA INTO THE DAY ON WEDNESDAY. THE FRONT WILL THEN
LINGER ALONG THE SOUTHEAST COAST THROUGH THE LATE WEEK TIME PERIOD
AND DISSIPATE. THE REMNANTS OF THE FRONT COULD LIFT BACK NORTH
THROUGH THE AREA EARLY NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
THIS EVENING AND TONIGHT...SHOWERS AND THUNDERSTORMS WILL CONTINUE
TO DEVELOP WITHIN A WARM AND MOIST ATMOSPHERE AHEAD OF A COLD FRONT
APPROACHING FROM THE WEST/NORTHWEST THIS EVENING. PWATS GREATER THAN
2.0 INCHES AND SBCAPES BETWEEN 3000-4000 J/KG WILL LIKELY SUPPORT
PRECIP ACTIVITY THROUGH AT LEAST SUNSET. GIVEN FASTER STORM MOTIONS
THAN PREVIOUS DAYS...THE THREAT OF FLASH FLOODING SHOULD REMAIN
SOMEWHAT LOW. HOWEVER...WE CAN NOT RULE OUT THE POSSIBILITY OF SOME
LOCALIZED FLOODING THROUGH LATE EVENING GIVEN THE DEEP MOISTURE OVER
THE AREA. A STRONG TO SEVERE THUNDERSTORM IS ALSO POSSIBLE THIS
EVENING INTO EARLY TONIGHT AS DRY MID LVL AIR BEGINS TO PUSH INTO
WESTERN ZONES. DAMAGING WIND GUSTS WILL BE THE PRIMARY CONCERN WITH
THUNDERSTORMS THIS EVENING.
SHOWER AND THUNDERSTORM ACTIVITY WILL LIKELY DIMINISH THROUGH
MIDNIGHT TONIGHT ONCE SUNSET OCCURS. HOWEVER...WE COULD SEE A FEW
SHOWERS AND/OR THUNDERSTORM THROUGH LATE TONIGHT AS THE COLD FRONT
BEGINS TO SHIFT OVER NORTHERN ZONES IN SOUTHEAST SOUTH CAROLINA AFTER
3 AM TONIGHT INTO EARLY MORNING. GIVEN THE TIMING OF THE FRONT...NO
SEVERE WEATHER IS ANTICIPATED. OVERNIGHT LOWS SHOULD RANGE IN THE
MID TO UPPER 70S TONIGHT...WARMEST NEAR THE COAST.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
WEDNESDAY AND WEDNESDAY NIGHT...ALOFT THE FORECAST AREA WILL REMAIN
ALONG THE SOUTHERN PERIPHERY OF THE TROUGH ASSOCIATED WITH THE DEEP
CLOSED LOW TO THE NORTH. THE COLD FRONT WILL START THE DAY BISECTING
THE AREA WITH THE MODELS DEPICTING QUITE THE PWAT GRADIENT FROM
NORTH TO SOUTH. THE FRONT WILL SLOWLY DRIFT SOUTHWARD THROUGH THE
DAY WHICH WILL KEEP PWATS ACROSS THE NORTHERN HALF OF THE AREA
AROUND 1.5 INCHES AND FALLING...WHILE TO THE SOUTH PWATS WILL
CONTINUE TO BE AROUND 2.2 INCHES CLOSER TO THE ALTAMAHA. THE DEEP
MOISTURE GRADIENT WILL NECESSITATE A GRADIENT IN POPS ALONG ROUGHLY
THE SAME LINES. LOCATIONS TO THE NORTH WILL SEE ISOLATED CONVECTION
AT BEST...WHILE AREAS FURTHER SOUTH WILL REQUIRE 40-50 POPS. THE
OVERALL SEVERE THREAT IS QUITE LOW...BUT AREAS ALONG AND SOUTH OF
I-16 WILL CONTINUE TO SEE THE POTENTIAL FOR LOCALLY HEAVY RAINFALL
FROM THE STRONGER STORMS THAT DEVELOP. OVERNIGHT...THE LAND BASED
CONVECTION WILL DISSIPATE WITH THE LOSS OF HEATING AND THERE MAY BE
A FEW SHOWERS/STORMS OFFSHORE. HIGHS WILL BE IN THE LOW 90S WITH
LOWS RANGING FROM THE UPPER 60S FAR INLAND TO THE MID 70S ALONG THE
COAST.
THURSDAY THROUGH FRIDAY...THE DEEP MOISTURE GRADIENT WILL MAKE SLOW
SOUTHWARD PROGRESS THROUGH THE END OF THE WEEK. THE FORECAST FOR
EACH DAY IS QUITE SIMILAR...THOUGH THE POP GRADIENT WILL DRIFT A
FURTHER TO THE SOUTH EACH DAY. THERE ARE SOME INDICATIONS WE COULD
SEE A FEW SHOWERS/STORMS DEVELOP ALONG THE SEA BREEZE ALONG THE
SOUTH CAROLINA COAST AS WELL ON FRIDAY SO SLIGHT CHANCE POPS HAVE
BEEN ADDED FURTHER TO THE NORTH. OTHERWISE...THE END OF THE WEEK
WILL BE MUCH QUIET THAN THE LAST SEVERAL DAYS HAVE BEEN. WE WILL
CONTINUE TO SEE HIGHS IN THE LOW 90S AND LOWS IN THE UPPER 60S
INLAND TO MID 70S AT THE COAST.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AN UPPER TROUGH PATTERN WILL PERSIST ACROSS THE ENTIRE EASTERN
UNITED STATES FOR MUCH OF THE EXTENDED PERIOD. THE REMNANTS OF THE
LATE WEEK COLD FRONT COULD MEANDER BACK THROUGH THE FORECAST AREA
ON SATURDAY...BEFORE AN INLAND SURFACE TROUGH TAKES SHAPE AND
SUPPORTS A MORE SOLID SOUTH/SOUTHWEST FLOW INTO EARLY NEXT WEEK.
MOISTURE PROFILES WILL BEGIN TO RECOVER SATURDAY AND STEADILY
INCREASE EACH DAY...ESPECIALLY AS STRONGER SHORTWAVE ENERGY SHIFTS
EAST MONDAY AND TUESDAY. CONVECTIVE COVERAGE SHOULD RETURN TO MORE
SEASONAL NORMALS...AND HAVE ADVERTISED RAIN CHANCES PEAKING IN THE
SOLID 30 PERCENT CHANCE RANGE DURING THE AFTERNOON PERIODS. HIGH
TEMPERATURES WILL VARY LITTLE THROUGH THE EXTENDED
FORECAST...GENERALLY REACHING THE LOWER 90S AWAY FROM THE LOCALLY
COOLER COASTLINE EACH DAY.
&&
.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
FLIGHT RESTRICTIONS ARE POSSIBLE AT BOTH CHS AND SAV TERMINALS EARLY
THIS AFTERNOON AS SHOWERS AND THUNDERSTORMS DEVELOP AND PASS OVER
THE AREA. THE GREATEST TIME OF THUNDERSTORMS SHOULD BE BETWEEN
18-22Z. THERE IS ALSO A LOW CHANCE OF FLIGHT RESTRICTIONS LATE
TONIGHT AS A COLD FRONT SLOWLY SHIFTS OVER THE REGION...BUT
CONFIDENCE IS TOO LOW TO INCLUDE IN THE TAFS AT THIS TIME. VFR
CONDITIONS SHOULD THEN PREVAIL BY 14Z WEDNESDAY AT BOTH TERMINALS.
EXTENDED AVIATION OUTLOOK...A MORE TYPICAL SUMMERTIME DIURNAL
SCATTERED SHOWERS/THUNDERSTORMS REGIME IS EXPECTED THROUGH LATE
WEEK. THERE WILL BE LOW CHANCES FOR DIRECT IMPACTS FROM
THUNDERSTORMS...PRIMARILY AT KSAV.
&&
.MARINE...
THIS EVENING AND TONIGHT...A SLIGHT ENHANCEMENT TO THE PRESSURE
GRADIENT WILL OCCUR OVER THE WATERS AS A COLD FRONT APPROACHES THE
WATERS LATE TONIGHT. WINDS WILL INCREASE TO A SOLID 15 KT IN
RESPONSE TO THE ENHANCEMENT...EXCEPT 15-20 KT OVER THE GEORGIA
OFFSHORE WATERS. SEAS SHOULD ALSO BUILD TO 2-4 FT...WITH A FEW 5 FT
SEAS POSSIBLE BEYOND 40 NM IN OFFSHORE GEORGIA WATERS.
WEDNESDAY THROUGH SUNDAY...A COLD FRONT WILL BE POSITIONED JUST
INLAND OF THE WATERS ON WEDNESDAY AND WILL SLOWLY DRIFT SOUTHWARD
THROUGH THE END OF THE WEEK. IMMEDIATELY AHEAD OF THE FRONT...THE
PRESSURE GRADIENT WILL BE TIGHT ENOUGH TO SUPPORT WINDS UP TO 15-20
KT AT TIMES LATE WEDNESDAY...BUT BELOW SMALL CRAFT ADVISORY
THRESHOLDS. THEREAFTER...THE FRONT AND THE PRESSURE GRADIENT WILL
WEAKEN AND FLOW WILL BECOME VARIABLE AT TIMES AND REMAIN BELOW 15
KT. SEAS WILL GENERALLY RUN 1-3 FT THROUGH THE PERIOD.
&&
.TIDES/COASTAL FLOODING...
TONIGHT...TIDES ARE FORECAST TO BE ABOVE 7.0 MLLW IN THE CHARLESTON
HARBOR. A COASTAL FLOOD ADVISORY WILL THEREFORE BE ISSUED FROM 7 PM
UNTIL 1 AM FOR ALL COASTAL COUNTIES IN SOUTHEAST SOUTH CAROLINA. A
PEAK TIDE LEVEL OF 7.2-7.5 FT MLLW IS FORECASTED IN THE CHARLESTON
HARBOR AROUND HIGH TIDE TONIGHT.
DUE TO LINGERING ASTRONOMICAL INFLUENCES...THE WEDNESDAY EVENING
HIGH TIDE MAY ONCE AGAIN PEAK AROUND SHALLOW COASTAL FLOODING
THRESHOLDS IN CHARLESTON HARBOR. A COASTAL FLOOD ADVISORY MAY BE
NEEDED.
