Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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 12:00Z, 6.8 hours before the alert went out and 186 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, May 28, 9:15 AM EDT, 5 hours 31 minutes before
AREA FORECAST DISCUSSION...UPDATE NATIONAL WEATHER SERVICE PEACHTREE CITY GA 915 AM EDT FRI MAY 28 2010 .UPDATE... UPDATED TO BETTER REFLECT THUNDERSTORM POTENTIAL THIS AFTERNOON TO INCLUDE THE POSSIBILITY OF GUSTY WINDS...SMALL HAIL AND FREQUENT LIGHTNING FROM THUNDERSTORMS. BDL && .SHORT TERM...PREVIOUS DISCUSSION /TODAY THROUGH SUNDAY/... CURRENT SATELLITE LOOP SHOWS LARGE MOISTURE PLUME EXTENDING FROM NE CANADA DOWN TO THE MID MISSISSIPPI RIVER VALLEY. THERE IS ALSO AN UPPER RIDGE OVER THE CENTRAL PORTION OF THE COUNTRY WHICH SHOULD CONTINUE TO BUILD NORTH AND EAST INTO THE GREAT LAKES REGION BY SUN/MON. THERE ARE A FEW WEAK WAVES ALONG THIS MOISTURE PLUME THAT SHOULD MOVE SE OVER THE NEXT FEW DAYS BRINGING INCREASED PULSE CONVECTION TO THE AREA. THROUGH THE SHORT TERM LOOKS LIKE WE ARE IN A DIURNAL TREND WITH AFTERNOON CONVECTION. FRI-MON...INSTABILITY INDICES PEAK EVERY DAY AROUND 18Z (CAPES EXPECTED IN THE 1500-3000 J/KG RANGE AND LIS AROUND -2 TO -5) DURING THE PRIME HEATING OF THE DAY. THIS COMBINED WITH INCREASED MOISTURE...SHOULD RESULT IN AFTERNOON SHRA/TSRA WITH ISOLATED SEVERE STORMS EXPECTED. SHEAR VALUES ARE VERY LOW THROUGH THE SHORT TERM SO NOT EXPECTING ANY TORNADIC ACTIVITY...JUST STRONG GUSTY WINDS...DIME TO QUARTER SIZE HAIL...AND PERIODS OF HEAVY RAIN. INSTABILITIES TAPPER OFF QUICKLY EACH DAY AFTER 00Z SO SHOULD SEE STORMS ENDING AROUND 02Z-04Z EACH EVENING AS WELL. DID NOT INCLUDED SEVERE WORDING IN THE FORECAST AS IT LOOKS LIKE IT WILL BE ISOLATED AT BEST. .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... AS WITH THE SHORT TERM WE CONTINUE WITH A PULSE CONVECTIVE ENVIRONMENT THROUGH DAY SEVEN. SHEAR CONTINUES TO BE ALMOST NON EXISTENT SO STILL ONLY LOOKING FOR GUSTY WINDS...HAIL AND HEAVY RAIN AS THE MAIN SEVERE THREATS. MOISTURE ALSO INCREASES GREATLY AS A FRONTAL SYSTEM MOVES SE OUT OF THE GREAT LAKES REGION MONDAY...AND INTO GA TUE/WED. THIS BOUNDARY LOOKS LIKE IT WILL STALL SOMEWHERE ACROSS CENTRAL/SOUTH GA...BECOMING A CATALYST FOR INCREASED DIURNAL CONVECTIVE ACTIVITY DAYS 5-7. AT THIS TIME WILL HOLD OFF ON SCATTERED SEVERE WORDING THAT FAR OUT IN THE FORECAST...BUT WE WILL BE WATCHING THIS CLOSELY AS THINGS DEVELOP. && .AVIATION... VFR CONDITIONS WILL PERSIST THROUGH 12Z SATURDAY. NOT MUCH CHANGE FROM THE PAST TWO DAYS WITH THE DEVELOPMENT OF AFTERNOON AND EVENING THUNDERSTORMS. WITH THE H5 LOW A LITTLE CLOSER TO THE CWA...FEEL THE CHANCE OF THUNDERSTORMS WILL BE A LITTLE BETTER THAN THE LAST COUPLE OF DAYS AND WILL GO WITH A PROB30 THIS AFTERNOON AND INTO THE EVENING. CONVECTION WILL DISSIPATE AFTER SUNSET. WINDS WILL REMAIN NORTHEAST TO EAST AT LESS THAN 10 KTS. && .PRELIMINARY POINT TEMPS/POPS...
