The episode as NWS FFC wrote it up.
A vigorous closed upper low was moving from the Midwest into the Ohio Valley during the period of June 21st through the 23rd. A slow moving cold front accompanied this system and was draped from Oklahoma into Ohio. High pressure aloft across north Florida was keeping a hot, humid, unstable air mass in place across Georgia. A complex of thunderstorms moved into northwest Georgia during the late afternoon/early evening before dissipating. As this activity moved into northwest Georgia, it began to decay and produced an area of strong, gusty outflow winds causing damage in several northwest Georgia counties. A separate area of less organized, isolated thunderstorms in east central Georgia also produced a small area of wind damage.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Atlanta, GA wrote its last area forecast discussion before the first event at Jun 21, 3:22 PM EST, 1 hour 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 422 PM EDT TUE JUN 21 2011 .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... PRIMARY CONCERN AGAIN IS CHC FOR SEVERE CONVECTION WED AND THURS. STORMS HAVE MANAGED TO DODGE CWA THIS AFTERNOON...NO ONE SEEMS TO BE COMPLAINING OTHER THAN THOSE WISHING FOR SOME RAIN. MODELS STILL IN GOOD AGREEMENT TO UPPER TROUGH WILL SLOWLY PROGRESS EAST REST OF THIS WEEK AND SOUTHERN FRINGE OF WESTERLIES WILL DIP INTO ALL OF NORTH GA. EXPECT STORMS IN AL TO WEAKEN THIS EVENING BUT STORMS FURTHER WEST TO PERSIST OVERNIGHT AND CONTINUE EAST INTO NW GA AFTER SUNRISE. THIS SCENARIO DEPICTED BY MOST MODELS INCLUDING 12Z GFS/15Z SREF MEAN/12Z ECMWF. 12Z AND 18Z NAM STILL ODD MEN OUT WITH NO INDICATION OF OVERNIGHT CONVECTION TO THE WEST...ALTHOUGH 18Z NAM DOES FIRE IT UP IN THE MORNING OVER NW GA. HAVE BUMPED POPS UP FOR LATE TONIGHT AND WED FOR NW 1/2 OF CWA. IF ENOUGH CLOUDS AND PRECIP CAN COME THROUGH IN THE MORNING...THIS WOULD DECREASE INSTABILITY AND LOW LEVEL FORCING AND HOPEFULLY JUST GIVING US SOME NEEDED RAIN. IF CONVECTION AND CLOUDS DISSIPATE IN THE MORNING...COULD BE IN FOR SOME REALLY ROUGH WEATHER AS VERTICAL WIND SHEAR WILL BE UNSEASONABLY STRONG. 0-6KM BULK SHEAR STILL PROGGED AT 20-25KTS. DAMAGING WINDS WOULD BE THE PRIMARY THREAT...BUT AGAIN DEPENDS ON EVOLUTION OF OVERNIGHT AND MORNING CONVECTION. FOR NOW...NAM THE ONLY MODEL REALLY SHOWING THIS. WILL HAVE TO WAIT AND SEE. AS WAVE MOVES SLOWLY EAST THURS...FLOW ALOFT OVER GA BECOMES MORE WESTERLY THAN SW AND A TAD WEAKER. MAY BE A LITTLE LESS COVERAGE OF STORMS AS RIBBON OF DRIER AIR WRAPS IN FROM THE WEST OVER NORTH GA. HAVE CONTINUED CHC POPS WITH PLENTY OF MOISTURE AND INSTABILITY OVER ALL BUT FAR NORTH GA. USED BIAS ADJUSTED MET GUIDANCE AND RECENT PERSISTENCE FOR MIN TEMPS AND BIAS ADJUSTED MAV/MET FOR MAX TEMPS. .LONG TERM /FRIDAY THROUGH TUESDAY/... WEAK UPPER TROUGH AXIS STILL PROGGED BY MED RANGE MODELS TO REMAIN OVER THE SOUTHEAST THROUGH TUESDAY. 12Z ECMWF A LITTLE FASTER PUSHING IT OUT BUT VERY LITTLE DIFFERENCE BETWEEN IT AND 12Z GFS AND GEFS MEAN. SHOULD KEEP US IN FAIRLY ACTIVE PATTERN WITH SCT DIURNALLY DRIVEN STORMS IN THE AFT/EVE WITH NEAR OR SLIGHTLY BELOW NORMAL MAX TEMPS. MIN TEMPS SHOULD STAY WARM. GOING FCST LOOKS GOOD AS 12Z RUNS NOT MUCH DIFFERENT THAN 00Z RUNS. SNELSON && .AVIATION... 18Z UPDATE...
