The radar

The Roanoke radar (KFCX), 143 km from the middle of the area, began a volume at 02:47 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, 2.8 hours before the alert went out and 62 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 Jul 8, 10:39 PM EDT, 6 minutes earlier.

Area forecast discussion, Jul 8, 10:39 PM EDT, 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1039 PM EDT FRI JUL 8 2011

.SYNOPSIS...
A WEAK FRONT WILL MOVE INTO THE AREA SATURDAY AND STALL OVER OR JUST
SOUTH OF THE AREA SUNDAY. WEAK HIGH PRESSURE WILL BUILD MONDAY
BEFORE ANOTHER WEAK FRONT MOVES IN BY MID WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
AS OF 1030 PM...THE CLUSTER OF STORMS ALONG THE I-77 CORRIDOR SHUD
EXIT BY ARND MIDNIGHT TO THE EAST....LEAVING SOME AREAS OF LGT
STRATIFORM RAIN INTO THE OVERNIGHT. HAVE UPDATED POPS FOR THAT.

ANOTHER SHORTWAVE WAS ANALYZED ON WATER VAPOR AND RUC APPROACHING
THE AREA FROM THE TN VLY. THIS FEATURE WILL CROSS THE AREA
OVERNIGHT. MEANWHILE...A SLOW-MOVING COLD FRONT ORIENTED NE-SW FROM
THE MID ATLC TO THE MID SOUTH...WILL SAG SWD INTO THE CWFA BY
DAYBREAK SATURDAY. MODELS SHOW SOME CONVERGENCE WITH THE
FRONT...COUPLED WITH VERY MOIST PROFILES AND SOME DPVA ALOFT. SO
WILL KEEP A SLGT CHC POP FOR MAINLY SHWRS...BUT A TSTM OR TWO NOT
OUT OF THE QUESTION. MILD TEMPS IN THE 60S MTNS AND LWR 70S PIEDMONT
LOOKS ON TRACK.

THE COLD FRONT WILL MOVE SOUTH OF OUR AREA TOMORROW
MORNING...MEANING THAT FORCING AND THE DEEPEST MOISTURE WILL NOT
COINCIDE WITH THE BEST HEATING OF THE DAY. WITH THAT IN MIND...ONLY
CHANCE POPS WILL BE CARRIED ON SATURDAY...WITH THE MAIN FOCUS
SHIFTING TO THE PIEDMONT BY AFTERNOON...WHERE THE BEST CHANCE OF
SEVERE WEATHER WILL EXIST. HIGH TEMPERATURES WILL RUN SLIGHTLY
ABOVE NORMAL AS HEIGHTS BEGIN TO RISE IN THE WAKE OF THE UPPER
TROUGH.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 205 PM FRIDAY...MODELS REMAIN IN DECENT AGREEMENT IN BUILDING
AN UPPER RIDGE OVER THE AREA SUN AND MONDAY. HOWEVER...THE MDLS
DISAGREE ON WHERE THE WEAK FRONTAL BOUNDARY STALLS AND THE AMOUNT OF
LOW LEVEL ELY MOIST FLOW ACROSS THE AREA. THE NAM IS THE DRIEST
PUSHING THE BOUNDARY FARTHER SOUTH...BUT STILL KEEPS MOISTURE AND
LOW LEVEL CONVERGENCE FROM THE UPPER SAVANNAH RIVER VALLEY INTO THE
MTNS. THE GFS AND SREF KEEP THE BOUNDARY FARTHER NORTH WITH MORE
MOISTURE ACROSS MUCH OF THE AREA. HAVE GONE WITH A BLEND KEEPING CHC
POP CONFINED TO THE WRN UPSTATE...NE GA AND THE SRN MTN/FOOTHILLS OF
NC WITH ISOLATED POP ELSEWHERE FOR SUN. WENT WITH SLIGHT CHC POP ALL
AREAS MONDAY...BUT THIS MAY BE TOO HIGH OUTSIDE OF THE MTNS AND
UPPER SAVANNAH RIVER VALLEY. POP WILL RETAIN A DIURNAL TREND. ABOVE
NORMAL HIGHS SUNDAY GO WELL ABOVE NORMAL MONDAY WITH RISING HEIGHTS.
LOWS REMAIN NEARLY STEADY AT NEAR TO SLIGHTLY ABOVE NORMAL.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 150 PM FRIDAY...UPPER RIDGE OVER THE AREA BEGINS TO RETROGRADE
AT THE BEGINNING OF THE PERIOD AS A TROF FORMS OFF THE EAST COAST.
THIS PUTS OUR AREA IN A WEAK NWLY FLOW. THIS ALLOWS WEAK SHORT WAVES
TO DROP DOWN TOWARD THE AREA PUSHING A FRONT IN FROM THE NW ON TUE.
THE GFS AND CANADIAN TRY TO PUSH THE FRONT SOUTH OF THE AREA WED AND
KEEP IT THERE THU AND FRI AS DRY HIGH PRESSURE BUILDS IN FROM THE
NORTH. THE ECMWF STALLS THE FRONT OVER THE AREA WED AND ONLY PUSHES
IT TO THE SRN CWFA FOR THU WITH SOME DRIER AIR BUILDING IN FROM THE
N FRI. THERE IS ALWAYS A QUESTION HOW FAR SOUTH A FRONT CAN GO THIS
TIME OF YEAR...SO HAVE TRENDED TOWARD THE ECMWF SOLN. THIS MEANS A
MAINLY DIURNAL POP TREND. WITH BEST CHC WEST TUE AND FRI AND CHC ALL
AREAS WED AND THU. WELL ABOVE NORMAL HIGHS TUE SLOWLY FALL TO NEAR
NORMAL FOR THU AND FRI AS HEIGHTS FALL. LOWS FOLLOW A SIMILAR TREND.

&&

.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
AT KCLT...STILL PLENTY OF STORMS NEAR THE TERMINAL...SO I WILL HAVE
A TEMPO FOR TS AND SOME RA AND GUSTY WINDS FOR FIRST HOUR OF 00Z
TAF. AFTER THAT...ANOTHER ROUND OF STORMS TO THE WEST MAY AFFECT THE
TERMINAL LATER THIS EVENING...SO I WILL KEEP CB MENTION FOR A FEW
HOURS. THINGS SHUD WIND DOWN BEHIND THAT LINE BY 06Z. AS FAR AS
STRATUS...FOG/HAZE/SMOKE LATER TONIGHT INTO SATURDAY...I MAY DO AN
AMENDMENT TO ADD SOME RESTRICTIONS. GUIDANCE WAS NOT VERY
IMPRESSED...BUT GIVEN ALL THE RAIN AND CONTINUED WEAK LLVL
FLOW...THINK THERE WILL BE FOG AND STRATUS AROUND SATURDAY MORNING.
BY MIDDAY...BACK TO VFR WITH SCATTERED SHRA/TSRA AGAIN...BUT
COVERAGE IS EXPECTED TO BE LOWER THAN LAST FEW DAYS. SO NO CB OR
SHRA MENTION AT THIS TIME. NELY WIND BEHIND A SLOW-MOVING COLD FRONT
IS EXPECTED...BUT SOME OF THE GUIDANCE KEEPS WINDS SELY.

ELSEWHERE...AT TIME OF 00Z TAF ISSUANCE...TS WAS AFFECTING
GMU/GSP/HKY...BUT THINGS SHUD PUSH OFF TO THE EAST OF THIS LINE BY
01Z. THERE IS STILL SOME CHC OF CONVECTION FOR THE REST OF THE
EVENING...SO WILL KEEP A MENTION OF CB. BY 06Z...SHUD BE FAIRLY
QUIET...BUT MOISTURE OF THE RAIN AND LIGHT FLOW AHEAD OF A
SLOW-MOVING COLD FRONT WILL ALLOW FOR PATCHY FOG AND STRATUS TO
DEVELOP AGAIN OVERNIGHT. KAVL AND KHKY HAVE THE HIGHEST CHC OF
FOG...BUT MAY NEED TO AMEND FOR GMU/GSP WHERE RAIN IS CURRENTLY
FALLING. WINDS WILL VEER FROM SW THIS EVENING TO NW BY DAWN...AS A
COLD FRONT MOVES THOUGH FROM THE NORTH. KAND WILL BE THE
EXCEPTION...WITH WESTERLY WINDS REMAINING SOUTH OF THE FRONT.
CONVECTION SATURDAY WILL BE MOST LIKELY NEAR THE FRONT AT KAND AND
KGMU...BUT CONFIDENCE IS TOO LOW TO CARRY CB.

OUTLOOK...A STALLED COLD FRONT ACROSS THE AREA ON SUNDAY IS EXPECTED
TO PUSH SOUTH ON MONDAY. AFTERNOON CONVECTIVE RESTRICTIONS
POSSIBLE...FOLLOWED BY MORNING FOG RESTRICTIONS WHERE RAIN FELL THE
DAY BEFORE. EXPECT SLIGHTLY DRIER CONDITIONS BY MONDAY.
