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 12:00Z, 2.9 hours before the alert went out and 134 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.

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 Jun 28, 10:05 AM EDT, 50 minutes earlier.
Area forecast discussion, Jun 28, 10:05 AM EDT, 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 1005 AM EDT TUE JUN 28 2005 .SHORT TERM (REST OF TODAY)... DEEP MOISTURE CONTINUES STREAMING UP FROM THE S-SW WITH SHOWERS AND SCT TSTMS...MAINLY ACROSS THE E 2/3 OF THE CWA ATTM. DO NOT EXPECT TO SEE MUCH SUN...AS WAS THE CASE YESTERDAY...SO SFC HEATING WILL BE MORE LIMITED...HENCE THE COOLER HIGHS FCST TODAY LOOK REASONABLE AND HAVE EVEN TWEAKED THEM DOWN A DEG OR TWO. PERIODS OF MODERATE RAIN ARE EXPECTED...ESPECIALLY FOR THE S FACING UPSLOPE AREAS AND THE CENTRAL AND E PART OF THE CWA ALONG BEST MOISTURE AXIS. EXPECT SHOWERS TO REDEVELOP ACROSS W ZONES THIS AFTN AND HAVE GONE WITH CAT POPS AND SCT TSTMS ACROSS CWA. && .PREVIOUS DISCUSSION... (ISSUED 242 AM EDT TUE JUN 28 2005) SHORT TERM (TODAY THROUGH THURSDAY NIGHT)... KGSP VAD WIND PROFILE IS EXHIBITING MORE OF A SOUTHERLY FLOW IN THE LOWER TROPOPHERE THAN THIS TIME YESTERDAY...BUT SHORT RANGE MODELS SUGGEST A BACKING TO SOUTHEAST AT THE LOWEST LEVELS THROUGH THE MORNING HOURS. WITH ABUNDANT CONVECTION DEVELOPING ACROSS THE UPSTATE...THE HEAVY RAIN WILL LIKELY TRAIN ONCE AGAIN FROM GSP INTO THE BLUE RIDGE. WILL MOST LIKELY NEED A FLASH FLOOD WATCH THIS MORNING IN AREAS THAT RECEIVED HEAVY RAINFALL YESTERDAY MORNING. MODEL SOUNDINGS AND TIME HEIGHT SECTIONS INDICATE VERY DEEP MOISTURE TODAY. LITTLE FORCING WILL THUS BE NEEDED FOR NUMEROUS TO WIDESPREAD SHOWERS AND THUNDERSTORMS. LESS MID LEVEL DRY AIR...HOWEVER...SHOULD KEEP SEVERE POTENTIAL MUCH MORE LIMITED. THE AXIS OF DEEPER TROPICAL MOISTURE WILL SLOWLY SHIFT EAST THROUGH WEDNESDAY AND INTO THURSDAY...AS WEAK UPPER TROUGH AXIS FINALLY MOVES EAST OF THE AREA. LOW LEVELS WILL REMAIN FAIRLY MOIST IN SPITE OF THE WESTERLY FLOW ON THURSDAY. LESS CLOUDINESS WILL ALLOW TEMPERATURES AND INSTABILITY TO RECOVER. THE AREA COULD BE SET UP FOR STRONG MCS DEVELOPMENT UPSTREAM WHICH WOULD HIT THE MOUNTAINS HARDEST IN THE THU NIGHT TIME FRAME. GIVEN ALL OF THE ACTIVITY WITH THE TROPICAL MOISTURE EARLY IN THE PERIOD...AND THEN POSSIBLE MCS ACTIVITY LATE...WILL ISSUE SPS TO ADDRESS CUMULATIVE RAINFALL THREAT THE NEXT COUPLE OF DAYS. LONG TERM (FRIDAY THROUGH MONDAY)... GFS APPEARS TO BE THE MODEL OF CHOICE FOR THE MEDIUM RANGE...WHICH KEEPS A WEAK UPPER TROUGH OVER THE SRN APPALACHIANS INTO THE WEEKEND. A STRONG UPPER TROF MOVES E ACROSS N STATES LATE IN THE WEEK...WHICH REINFORCES THE TROF OVER THE E U.S. AS IT MOVES INTO IT. A COLD FRONT DROPS SE INTO N GA AND THE CAROLINAS FRI...THEN STALLS S OF THE AREA. WEAK SHORT WAVES MOVG THROUGH THE UPPER FLOW COULD INITIATE CONVECTION AT ANY TIME THROUGH THE PERIOD SO A CHANCE OF SHOWERS AND THUNDERSTORMS HAVE BEEN KEPT IN THE GRIDDED FORECAST EACH DAY...WITH A TENDENCY FOR MORE ACTIVE CONVECTION DURING THE WARMER AFTERNOON AND EVENING TIMEFRAME. LOWERED SKY COVER AND ADJUSTED SOME DEW POINTS LOWER NE CORNER FOR BETTER FIT WITH NEIGHBORS. AVIATION... CONVECTION MOVING N IN TO KAND/KGSP AREA...AND WILL COVER IN TEMPO FIRST TWO HOURS. EXPECTING MVFR WITH TEMPO IFR IN RAIN MOISTED AIR MASS OVERNIGHT. EXPECT HEATING AND SOME VERTICAL MOTION IN SW FLOW ALOFT TO MIX VSBY/CIGS TO LOW VFR BY MID MORNING. TIMING INDIVIDUAL UPPER FEATURES WILL BE DIFFICULT AS MODELS DISAGREE ON FREQUENCY OF IMPULSES...SO FOR NOW WILL STICK WITH TIME OF BEST HEATING FOR TEMPO AFTERNOON CONVECTION... WHICH WORKED WELL YESTERDAY...AND IS WHEN GUIDANCE HAS HIGHEST POPS. WILL BRING IN LOW VFR FOG BY MID EVENING...ASSUMING ANOTHER ROUND OF AIR SOAKING PRECIPITATION ENDING BY LATE EVENING AND WINDS GOING LIGHT. HYDROLOGY... WILL ISSUE FLASH FLOOD WATCH FOR LOCATIONS THAT RECEIVED 3 TO 9 INCHES OF RAIN YESTERDAY...FROM GSP TO AVL AND THE ADJACENT NC FOOTHILLS. FFG VALUES ARE GENERALLY IN THE 1 TO 2 INCH RANGE FOR 1 TO 3 HOUR RAINFALL DUE TO EXCESSIVE RAIN MONDAY MORNING. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE.
