The radar
The Greer radar (KGSP), 69 km from the middle of the area, began a volume at 03:54 UTC, the scan nearest the moment this went out.
Open the radar archive at this moment
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
Peachtre/Fal Fld, GA (KFFC), launched 00:00Z, 3.9 hours before the alert went out and 251 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 GREENVILLE-SPARTANBURG SC
1028 PM EDT THU APR 11 2013
.SYNOPSIS...
A STRONG COLD FRONT WILL CROSS THE WESTERN CAROLINAS AND NORTHEAST
GEORGIA TONIGHT. DRY HIGH PRESSURE WILL THEN BUILD IN FROM THE WEST
AND PERSIST THROUGH THE WEEKEND. AN UPPER LEVEL DISTURBANCE WILL
DEVELOP OVER THE GULF COAST SUNDAY AND BRING MOISTURE BACK ACROSS
THE REGION THROUGH THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /THROUGH FRIDAY/...
0230 UTC UPDATE...THE CURRENT WATCHES ARE STILL IN EFFECT...NO
CHANGES WITH THIS UPDATE. A LINE OF MULTI-CELL/EMBEDDED SUPERCELL
STORMS ARE ENTERING THE SWRN EDGE OF THE CWFA ATTM. SEVERE/TORNADO
THREAT EXISTS WITH THIS LINE AS IT MOVES INTO EXTREME NE GA. A
COUPLE OF CELLS IN THE DOWNSTREAM CONVECTION HAVE BECOME SEVERE. THE
APPROACH OF THE MID/UPR SHORTWAVE SEEMS TO BE FINALLY ERODING THE
MID LVL CAP...AND ALLOWING FOR STRONGER UPDRAFTS...WHILE SHEAR ALSO
IMPROVES. NC MTNS TOR WATCH IN EFFECT TILL 2 AM...THE REST OF THE
AREA TILL 4 AM.
2330 UTC UPDATE...FORGOT TO SEND UPDATED AFD TO ACCOUNT FOR A
TORNADO WATCH FOR ALL OUR NC MTN COUNTIES UNTIL 06Z. A CLUSTER OF
SEVERE TSTMS ARE TRACKING NE ACRS N-CENTRAL GA/SE TN...AND WILL
ENTER THE NC MTNS WITHIN THE NEXT COUPLE HOURS. MEANWHILE...AS
EXPECTED...SCATTERED SHWRS/TSTMS CONTINUE TO INCREASE IN COVERAGE
OUT AHEAD OF THIS ACTIVITY ACRS THE CWFA. SO FAR..A FEW STORMS ACRS
THE MIDLANDS HAVE BEEN REACHING OBJECTIVE SEVERE CRITERIA ON RADAR.
ALSO...WITH THE FRONTAL BAND ENTERING GA...A NEW TORNADO WATCH WILL
BE ISSUED FOR THE REMAINDER OF OUR CWFA THRU 08Z. THE MAIN THREATS
STILL EXPECTED TO BE DAMAGING WINDS AND ISOLATED TORNADOES. WITH
THESE STORMS BEHIND HYBRID SUPERCELLS...LARGE HAIL IS ALSO A THREAT.
2030 UTC UPDATE...DELAYED TIMING OF THE INCREASING POPS FOR THE
REMAINDER OF THE AFTN/EARLY EVENING...PER RADAR TRENDS.
OTHERWISE...FCST LOOKS ON TRACK.
THIS AFTERNOON...SCT CONVECTIVE SHOWERS/STORMS HAVE DEVELOPED OVER
SRN GA AND SC IN WARM MOIST SOUTHERLY FLOW IN WARM SECTOR OF MIDWEST
CYCLONE. THIS ACTIVITY IS NOW BEGINNING TO SPREAD NORTHWARD INTO THE
SRN PORTION OF THE CWFA. CAPPING WARM LAYER ALOFT CURRENTLY SEEMS TO
BE INHIBITING ANY SEVERE WEATHER. AS SFC HEATS FURTHER AND THE CAP
WEAKENS WITH TROUGHING ALOFT...DEEP SFC BASED CONVECTION WILL BE
POSSIBLE. DEEP SHEAR OVER THE CWFA LOOKS TO BE TOO WEAK FOR
SUPERCELLS FOR MOST OF THE AFTERNOON...THOUGH FAVORABLE BRN AND EHI
FOR ROTATING UPDRAFTS WILL BE PRESENT WITH SOME CLOCKWISE TURNING
EVIDENT IN HODOGRAPHS. SEVERE WINDS NOT OUT OF THE QUESTION THOUGH
LARGE HAIL IS LESS OF A THREAT DUE TO THE MODEST INSTABILITY.
DEEP SHEAR INCREASES STEADILY AHEAD OF A COLD FRONT WHICH WILL PUSH
ACROSS THE AREA LATE TONIGHT. THOUGH SFC BASED INSTABILITY WILL WANE
AROUND SUNSET SW WINDS ARE STRONG ENOUGH TO MAINTAIN A LLVL MIXED
LAYER AND ELEVATED INSTABILITY SO THUNDER IS STILL POSSIBLE...AND THE
INCREASING SHEAR WILL MAINTAIN DAMAGING WIND THREAT. NEAR THE
FRONT...LLVL COLD ADVECTION BRINGS THE MIXED LAYER BACK TO THE SFC
AND SFC BASED INSTABILITY RETURNS...ON THE ORDER OF A FEW HUNDRED J
OF CAPE. LENGTHENING AND CURVING HODOGRAPH INDICATES THREAT IS
ESPECIALLY STRONG NEAR THE FRONT. FROPA TIMED SIMILARLY ON GFS/NAM
AND SHOULD ENTER THE WRN ZONES AROUND MIDNIGHT...DEPARTING THE EAST
AROUND DAYBREAK. LINGERING MOISTURE BEHIND THE FRONT SHOULD MAINTAIN
SOME STRATUS/STRATOCU AND PERHAPS SOME SCT SHOWERS BUT THESE WILL
DEPART THE EASTERN ZONES BY MIDDAY.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AS OF 115 PM THURSDAY...A RATHER STRAIGHTFORWARD SYNOPTIC PATTERN
DEVELOPS THROUGH THE SHORT TERM. THE MODELS AGREE WELL WITH HEIGHTS
RISING AND THE H5 FLOW TRANSITIONING FROM BROADLY CYCLONIC TO
ANTICYCLONIC THROUGH 00Z MON. THERE WILL BE NO GOOD CHANCE OF PRECIP
THROUGH THE PERIOD AS DEEP LAYERED DRYING MOVES IN FROM THE NW AND
PERSISTS UNTIL UPPER/MID CLOUDS DEVELOP OUT OF THE SW BY MID DAY
SUN. SLIGHT POPS WERE MAINTAINED VERY LATE AROUND 21Z SUN AS
ISENTROPIC LIFT DEVELOPS ALONG WITH INCREASING MOISTURE FLUX. A LOOK
AT BL THETA/E SHOWS FAIRLY WEAK CAA FRI NIGHT...HOWEVER VERY GOOD
INSOLATION AND A DOWNSLOPING COMPONENT WILL OFFSET THE COOLING AND
ALLOW MAX TEMPS A COUPLE DEGREES ABOVE NORMAL. WITH THE INCREASING
UPPER CLOUDS SUN...INSOLATION WILL BE LIMITED YET H100/H85
THICKNESSES INCREASE BY 25 M FROM SAT AFTERNOON VALUES...THUS STILL
EXPECT A CONTINUED INCREASE IN MAXIMUM TEMPS...ABOUT 4-5 DEGREES
ABOVE NORMAL. MIN TEMPS WILL BE RIGHT AROUND NORMAL WITH PERHAPS
ENOUGH COOLING ACROSS THE HIGHER NC MTN TERRAIN TO PRODUCE PATCHY OR
AREAS OF FROST.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AS OF 200 PM THU...ALL MEDIUM RANGE MODELS CONTINUE TO FORECAST A
SOUTHERN STREAM WAVE TO MOVE ACROSS THE FORECAST AREA ON MONDAY.
ALSO...ALL THE MODELS SHOW SOME DEGREE OF QPF RESPONSE WITH THIS
FEATURE. THEREFORE...WILL CONTINUE WITH THE IDEA OF FEATURING
SCATTERED TYPE POPS BEGINING LATE SUNDAY NIGHT AND CONTINUING
THROUGH MONDAY. IT APPEARS THAT THE SOUTHERN PORTION OF THE AREA
MIGHT HAVE BETTER COVERAGE AND THIS WILL BE LIKELY BE REFINED WITH
LATER FORECASTS.
AFTER THE WAVE EXITS TO THE EAST MONDAY NIGHT...AN UPPER RIDGE IS
FORECAST TO DEVELOP OVER THE SE STATES AND LINGER THROUGH MIDWEEK. I
LIKE THE ECM DEPICTION OF THE SENSIBLE WEATHER IN THE TUE/WED
TIMEFRAME WHICH DEPICTS ESSENTIALLY DIURNAL TYPE SHOWERS/TSTORMS
WHICH FITS THE CONCEPTUAL MODEL OF THE EXPECTED WEATHER PATTERN.
HENCE WILL FORECAST SCATTERED AFTERNOON SHOWERS/TSTORMS...BUT KEEP
THEM CONFINED TO THE MOUNTAINS. ON THU...A COLD FRONT WILL APPROACH
FROM THE WEST AND PERHAPS MOVE THROUGH THE AREA BY LATE IN THE DAY
PER THE GFS. THE ECM IS SLOWER AND HPC HAS TAKEN A COMPROMISE
SOLUTION WHICH STILL RAMPS UP CHANCE POPS ACROSS THE AREA ON THU.
TEMPERATURES WILL BE NEAR SEASONAL LEVELS ON MONDAY AND THEN WARM TO
WELL ABOVE NORMAL ON TUE/WED AND THEN BACK TO NEAR NORMAL FOR THU
DUE TO CLOUDS AND PRECIP.
&&
.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
AT KCLT...NO MAJOR CHANGES TO THE TAF FOR 00Z. STILL LOOKS LIKE TWO
ROUNDS OF SHOWERS/THUNDERSTORMS TO AFFECT THE FIELD DURING THE
PERIOD. THE FIRST BATCH IS EXPANDING IN COVERAGE ACRS CENTRAL SC
ATTM...AND LIFTING NWD. THIS ACTIVITY WILL AFFECT CLT IN THE 01-04Z
TIME FRAME...AND BE SCATTERED IN NATURE (SO WILL KEEP JUST A TEMPO
FOR TS). THE SECOND ROUND OF STORMS WILL BE ASSOCIATED WITH A COLD
FROPA PROVIDING STRONG FORCING IN THE 04-09Z TIME FRAME. WILL GO
PREVAILING TSRA FOR THIS ACTIVITY...AS IT SHOULD BE MORE SOLID IN
COVERAGE. TRAILING STRATIFORM RAIN/EMBEDDED TS WILL LIKELY LINGER
THRU ABOUT 12Z. IFR/MVFR CIGS SHUD GRADUALLY IMPROVE FRI
MORNING...AS DRY W/NWLY FLOW WILL FILTER IN BEHIND THE FRONT. THE
SFC WINDS WILL STAY SWLY AND BECOME SOMEWHAT GUSTY AS SKIES CLEAR
FRIDAY AFTN.
ELSEWHERE...SCATTERED SHRA/TSRA ARE INCREASING IN COVERAGE THIS
EVENING ACRS THE REGION...BUT HAVE REMAINED GARDEN VARIETY SO FAR.
WILL HANDLE THIS ACTIVITY WITH TEMPO GROUPS FOR THE NEXT 2-4 HOURS.
THERE MAY BE BRIEF LULL IN ACTIVITY...ESP IN THE UPSTATE BEFORE A
MORE SOLID LINE OF TSRA CROSSES THE AREA FROM WEST TO EAST IN THE
03-08Z TIME FRAME. WILL GO WITH PREVAILING TSRA AT ALL SITES.
TRAILING STRATIFORM RAIN/EMBEDDED TS WILL LINGER DURING PRE-DAWN
HOURS...THEN CLEAR OUT BY DAYBREAK. STRATUS SHUD IMPROVE FRIDAY
MORNING...AS DRY AIR FILTERS IN BEHIND THE FRONT. VFR CONDITIONS
WITH SOMEWHAT GUSTY SW WINDS (NW AT KAVL) EXPECTED FRIDAY AFTN.
OUTLOOK...DRY HIGH PRESSURE WILL BUILD INTO THE REGION THROUGH THE
WEEKEND.
