The radar

The Greer radar (KGSP), 130 km from the middle of the area, began a volume at 04:02 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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

Greensboro/Hi Pt, NC (KGSO), launched 00:00Z, 4.0 hours before the alert went out and 123 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.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this flash flood warning went out at Aug 3, 10:26 PM EDT, 1 hour 33 minutes earlier.

Area forecast discussion, Aug 3, 10:26 PM EDT, 1 hour 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1026 PM EDT FRI AUG 3 2012

.SYNOPSIS...
CIRCULATION AROUND HIGH PRESSURE CENTERED OVER THE WESTERN ATLANTIC
WILL KEEP THE SOUTHERN APPALACHIAN REGION WARM AND HUMID THROUGH THE
WEEKEND. A COLD FRONT IS EXPECTED TO SLOWLY SWEEP ACROSS THE WESTERN
CAROLINAS AND NORTHEAST GEORGIA EARLY NEXT WEEK...POSSIBLY BECOMING
STATIONARY AND LINGERING INTO LATE IN THE WORK WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
0230 UTC UPDATE...POPS AND QPF HAVE BEEN INCREASED IN THE GA AND SC
MOUTNAINS...AND IN THE SW NC PIEDMONT...PER RADAR TRENDS...AND LOWER
POPS WILL BE CARREID IN THE NC MOUTNAINS AND FOOTHILLS.

AT 930 PM EDT...A WEAK UPPER TROUGH WAS LOCATED ALONG THE SOUTHEAST
COAST...BETWEEN A WESTERN ATLANTIC RIDGE...AND ONE CENTERED OVER TX.
A MID LEVEL SHORTWAVE WAS ANALYZED CROSSING THE CENTRAL AND SOUTHERN
APPALACHIANS. SCATTERED CONVECTION WAS FOCUSED NEAR THE INTERSTATE
77 CORRIDOR...AND THE SOUTHERN BLUE RIDGE ESCARPMENT. THIS ACTIVITY
IS EXPECTED TO GRADUALLY WIND DOWN AFTER MIDNIGHT WITH THE LOSS OF
HEATING. VERY LOW CLOUDS ARE EXPECTED TO FORM AGAIN LATE TONIGHT.
GUIDANCE HAS BEEN SUPPORTING LOW CLOUDS AND FOG DEVELOPMENT ACROSS
MUCH OF THE AREA...BUT HAS BEEN OVERDONE WITH FOG LATELY...
ESPECIALLY EAST OF THE MOUNTAINS...AND ONLY LIMITED FOG WILL BE
CARRIED TOWARD DAYBREAK. MINIMUM TEMPERATURES WILL BE SLIGHTLY ABOVE
NORMAL IN A MOIST AIR MASS.

ON SATURDAY THE UPPER TROUGH WEAKENS QUICKLY AS THE ATLANTIC RIDGE
STARTS TO BUILD BACK INTO THE REGION. THE WEAKENING OF THE TROUGH IS
A LITTLE FASTER THAN WHAT WE/D BEEN EXPECTING. LAYER RH/S WILL
REMAIN HIGH AND EVEN WITH VERY WEAK FORCING...THERE SHOULD BE PLENTY
OF CONVECTION OVER THE HIGH TERRAIN AND A LITTLE LESS OUT ACROSS THE
FOOTHILLS AND PIEDMONT. THE SEVERE AND FLOODING RISK DON/T LOOK AS
GREAT TOMORROW. INTERESTINGLY...THE STRONGEST FORCING OF THE DAY
COULD COME IN THE FORM OF THE SEA-BREEZE FRONT WHICH THE NAM BRINGS
INTO THE SE ZONES EARLY IN THE EVENING.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 145 PM EDT...EXPECT SOME ONGOING SCATTERED CONVECTION SATURDAY
EVENING TO WANE RATHER QUICKLY AS SUBTROPICAL RIDGE BUILDS WESTWARD
INTO THE AREA SAT NIGHT. HENCE...THE SAT OVERNIGHT THROUGH SUNDAY
MORNING IS EXPECTED TO BE TRANQUIL. ON SUNDAY AFTERNOON...UPSLOPE
FLOW AND THE APPROACH OF A WEAK COLD FRONT FROM THE NW SHOULD
TRIGGER SCATTERED TO NUMEROUS SHOWERS/THUNDERSTORMS ACROSS THE
MOUNTAINS. ONLY ISOLATED TO WIDELY SCATTERED ACTIVITY IS EXPECTED
ELSEWHERE. THE MODELS BRING THE FRONTAL BOUNDARY INTO THE MOUNTAINS
SUNDAY NIGHT WHICH NECESSITATES MAINTAINING AT LEAST SCATTERED POPS
THERE. ON MONDAY...THE FRONT IS FORECAST TO LAY OUT ACROSS THE
WESTERN CAROLINAS INTO NE GA WHICH SHOULD BE A FOCAL POINT FOR
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS. MAXIMUM
TEMPERATURES ARE EXPECTED TO BE NEAR CLIMO WITH MIN TEMPERATURES
ABOUT A CATEGORY ABOVE AVERAGE.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 1 PM EDT FRIDAY...THE MEDIUM RANGE IS EXPECTED TO FEATURE
SOME DEGREE OF BROAD UPPER TROFFING OVER THE EASTERN U.S. WITH
PERHAPS SOME AMPLIFICATION IN THE TROUGH TOWARD THE END OF THE
PERIOD. THE PERSISTENT TROUGH AND THE PRESENCE OF THE FRONT WILL
CONTINUE TO TRIGGER SHOWERS AND THUNDERSTORMS THROUGH TUE...WITH AN
UPTICK DURING THE FAVORED AFTERNOON AND EVENING TIME PERIOD. THERE
IS SOME DIVERGENCE IN THE GUIDANCE IN REGARD TO HOW FAR SOUTH THE
AFOREMENTIONED FRONT GOES. THE ECM CAMP TAKES THE FRONTAL BOUNDARY
JUST SOUTH OF THE AREA ON WED AND BRINGS SOMEWHAT DRYER INTO THE
REGION FOR WED INTO THU. THIS WOULD PRODUCE A DECREASE IN
SHOWER/THUNDERSTORM ACTIVITY FOR WED INTO THU. ON THE OTHER HAND...
THE GFS HANGS UP THE BOUNDARY OVER THE AREA THROUGH THE PERIOD WITH
A CONTINUATION OF ENHANCED SHOWER AND THUDNERSTORM ACTIVITY THROUGH
THE END OF THE WEEK. HPC SIDED WITH THE ECM FRONTAL POSITION. WE
GENERALLY STAYED CLOSE TO HPC GUIDANCE WITH HIGHER THAN CLIMO POPS
FOR TUE AND THEN SOMEWHAT LOWER THAN CLIMO...ESPECIALLY ACROSS THE
MOUNTAINS FOR WED. BASICALLY CLIMO POPS RETURN FOR THE END OF THE
WEEK. USED A BLEND OF HPC/GMOS FOR TEMPS WHICH ESSENTIALLY IS CLOSE
TO CLIMO.

&&

.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
AT KCLT...CONVECTIVE ACTIVITY IS EXPECTED TO CONTINUE NEAR THE FIELD
FOR SEVERAL HOURS THIS EVENING AS A MID LEVEL SYSTEM CROSSES THE
EAST COAST...POSSIBLY ACCOMPANIED BY MVFR CIG AND VSBY. OTHERWISE...
LOW VFR CIGS ARE EXPECTED UNTIL EARLY MORNING...WHEN GUIDANCE
SUGGEST IFR CIGS IN A MOIST BOUNDARY LAYER. GUIDANCE CIG HEIGHTS
WERE RAISED ABOUT 500 FEET FOR CONTINUITY WITH CIGS FROM THIS
MORNING...AS CONFIDENCE IS LIMITED IN THE LOW END IFR MODEL CIG.
THIS LEAVES KCLT WITH A LOW END MVFR CIG AROUND DAYBREAK. MODEL VSBY
WAS MVFR...BUT THE MODELS HAVE BEEN TOO LOW WITH VSBY...AND VFR WILL
BE CARRIED FOR NOW. CONVECTIVE CHANCES FOR SATURDAY AFTERNOON ARE
HIGH ENOUGH TO CARRY A PROB30. SOUTHERLY WINDS WILL PREVAIL.

ELSEWHERE...MOUNTAIN CONVECTION IS EXPECTED TO DEVELOP ACROSS THE
MOUNTAINS AND INTO THE FOOTHILLS THIS EVENING...AND MVFR CIG AND
VSBY RESTRICTIONS WILL BE POSSIBLE. AFTERWORDS...LOW VFR CIGS CAN BE
EXPECTED INTERMITTENTLY UNTIL SEVERAL HOURS BEFORE DAWN. AT THAT
POINT MODEL GUIDANCE IS QUITE DIRE WITH CIG HEIGHTS...BUT WITH LOW
CONFIDENCE IS SUCH LOW CIGS...A GENERAL IFR WILL BE CARRIED...EXCEPT
VFR AT KAND. GUIDANCE FAVORS MVFR VSBY EAST OF THE MOUNTAINS...AND
LIFR IN THE MOUNTAIN. BASED ON TRENDS FROM YESTERDAY AND LIMITED
CONFIDENCE...IFR WILL BE CARRIED IN THE MOUNTAINS...MVFR ALONG
INTERSTATE 40...AND VFR TO THE SOUTH. SATURDAY AFTERNOON CONVECTIVE
CHANCES WARRANT PROB30 AT ALL LOCATIONS. WINDS WILL GENERALLY BE
FROM THE S OR SE.

OUTLOOK...ISO/SCT AFTN-EVE TSTMS ACROSS THE AREA EACH DAY. MTN VLYS
WILL SEE BEST CHANCE OF MORNING LOW CLOUDS/FOG.
