The episode as NWS FFC wrote it up.
An upper short wave was moving from the central into the eastern U.S. around a subtropical ridge located over south Texas. A cold front accompanied the short wave. A warm, moist, unstable air mass continued across the southeastern U.S. The combination of these features provided ample support for scattered to numerous thunderstorms during the afternoon and evening hours. A number of these became strong producing penny-sized hail. Isolated storms became severe producing quarter-sized hail and damaging downburst winds. The most notable storm affected Jackson county in northeast Georgia where damaging downburst winds caused considerable damage to a large commercial building.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 148 PM EDT SAT JUN 11 2011 .UPDATE... /ISSUED 1026 AM EDT SAT JUN 11 2011/ CU ALREADY DEVELOPING...WHICH IS AHEAD OF YESTERDAY AND MORE LIKE THURSDAY. GFS/RUC/HRRR ALL INDICATE GOOD COVERAGE OF THUNDERSTORMS THIS AFTERNOON. WILL THEREFORE INCREASE POPS TO HIGH CHANCE FOR THIS AFTERNOON AND ADD WORDING OF HEAVY RAIN AS STORMS WILL NOT BE MOVING MUCH AS WELL AS HIGH K INDEX VALUES. NO OTHER CHANGES PLANNED. && .SHORT TERM /TODAY THROUGH MONDAY/... /ISSUED 725 AM EDT SAT JUN 11 2011/ STORMS CONTINUE AT THIS HOUR...FEEDING OFF NARROW STRIP OF 1000 TO 1500 J/KG MIXED LAYER CAPE FROM NE GEORGIA TO JUST NORTH OF COLUMBUS. THESE VALUES ARE DOWN FROM AFTERNOON HIGHS AND HAS RESULTED IN LESS ROBUST CONVECTION WITH JUST A FEW STRONG STORMS NOTED SINCE MIDNIGHT. OVERALL TREND IN SHORT TERM MODELS IS FOR ACTIVITY TO CONTINUE ITS DOWNWARD TREND INTO THE REMAINDER OF THE OVERNIGHT PERIOD. OTHERWISE...MSAS ANALYSIS INDICATES A CONTINUED VERY WEAK FLOW PATTERN IN PLACE WITH RIDGE OFF THE ATLANTIC COAST INTO SOUTHEAST GA AND STILL INDICATIONS OF A WEAK TROUGH OVER NORTHWEST SECTIONS OF THE FORECAST AREA...LIKELY AIDING INITIATION OF STORMS. FOR TODAY...MODELS INDICATE A NEARLY IDENTICAL PATTERN FOR STORM COVERAGE AS WHAT WE SAW TODAY. RIDGE AXIS DOES TRY TO PUSH A LITTLE FURTHER INLAND WHICH WOULD ALLOW FOR DRIER AIR TO CUTOFF MORE OF THE FORECAST AREA FROM PRECIP CHANCES. SHOULD BE A SHARP GRADIENT TO POPS AS LATE DEVELOPING SEABREEZE PUSHES IN AND ALONG WITH AFOREMENTIONED TROUGH FORMS A STRONG CONVERGENCE ZONE OVER NORTHWEST GA. RECENT MODEL TRENDS SHOW THIS OCCURRING FROM AHN TO ATL AND SOUTHWEST AS OPPOSED TO THE FAR NW CORNER. WILL THEREFORE ADJUST POPS TO REFLECT HIGHEST COVERAGE (35 TO 40%) SLIGHTLY TO THE SOUTH OF PREVIOUS FORECAST. GETTING SIMILAR CAPE VALUES OFF THE GFS BUFR SOUNDINGS WHICH ARE NON IMPRESSIVE FOR THIS TIME OF YEAR. STILL EXPECT ISOLATED STRONG TO PERHAPS A SEVERE THUNDERSTORM WITH THE MORE ROBUST ACTIVITY. SUNDAY WILL BE THE FIRST DAY IN QUITE A WHILE IN WHICH WE ACTUALLY SEE INFLUENCES FROM NORTHERN STREAM UPPER LEVELS AS RIDGE AXIS IS SHUNTED WESTWARD. AT THE SURFACE...1020 MB HIGH BUILDING OVER THE OHIO VALLEY WILL BRIDGE EASTWARD ALLOWING FOR A TROUGH OF LOW PRESSURE TO ENTER OUR FORECAST AREA. INCREASING MOISTURE ALONG WITH CONVERGENCE GENERATED ALONG THE TROUGH AS WELL AS HINTS OF SHORTWAVE ENERGY DURING THE AFTERNOON ALL POINT TO INCREASED RAIN CHANCES. WILL CARRY GENERIC 40 PERCENT AREAWIDE FOR NOW AND LATER SHIFTS REFINE FURTHER. BIGGEST CHANGE IN THE SHORT TERM IS THE GFS NOW COMING AROUND TO FAVOR EARLIER NAM AND ECMWF SOLUTIONS OF BRINGING FRONT AND ASSOCIATED DRY AIR ALL THE WAY THROUGH THE FORECAST AREA ON MONDAY. THIS WOULD ACT TO SUPPRESS ANY AND ALL CONVECTION FOR MON AFTERNOON AND AT THIS POINT WILL LEAVE GRIDS POP FREE. .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... /ISSUED 725 AM EDT SAT JUN 11 2011/ DIFFICULT TO ASCERTAIN HOW EARLY NEXT WEEK IS GOING TO BE AS MOISTURE LOOKS TO BE VERY LIMITED BUT NORTHWEST FLOW ALOFT PROMISES INCREASED MID LEVEL ENERGY FOR POTENTIAL STORMS TO FEED OFF OF. FOR NOW WILL FAVOR THE OVERNIGHT IN THIS SETUP WITH JUST 20 PERCENT FOR THE NORTHERN ZONES. BETTER CHANCES ON WED AND THU AS ZONAL FLOW ALOFT DEVELOPS INTO A BROAD EAST COAST TROUGH. 23 && AVIATION... 18Z UPDATE...
