The episode as NWS FFC wrote it up.
A strong subtropical ridge persisted across Texas, but was beginning to build wastward into the mid-south and southeast U.S. An upper trough was located across the northeast into the mid-Atlantic region. This provided Georgia with unstable northwest flow aloft. Meanwhile...a weak cold front was moving slowly south through central Georgia. Hot temperatures and dewpoints in the low and mid 70s made for a very unstable atmosphere across the region. Scattered thunderstorms developed during the mid-afternoon and persisted into the evening. The most persistent and intense thunderstorms originated from a cluster of thunderstorms that developed in northeast Georgia and slowly worked its way south-southwest into central Georgia. Intense lightning and damaging downburst winds were noted with some of the thunderstorms, along with very heavy rain.

NWS Atlanta, GA wrote its last area forecast discussion before the first event at Aug 1, 1:20 PM EST, 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 220 PM EDT SUN AUG 1 2010 .UPDATE... WEAK BOUNDARY NEARLY BI-SECTING THE CWA WILL KEEP SLIGHTLY COOLER TEMPS TO THE EAST AND HOT TEMPS TO THE WEST. WEAK SHORT WAVE SEEN ON THE WATER VAPOR IMAGERY IS STRONG ENOUGH TO CAUSE A FEW SHOWERS EARLIER OVER SOUTHEAST TENNESSEE. THIS WAVE CONTINUE TO MOVE SOUTHEAST. DAYTIME HEATING MAY AID THE SHORT WAVE IN INITIATING SCATTERED SHOWERS/TSTORMS THIS AFTERNOON. CURRENT FORECAST IS HANDLING ALL ELEMENTS WELL AND NO CHANGES PLANNED. && .PREV DISCUSSION... /ISSUED 645 AM EDT SUN AUG 1 2010/ SHORT TERM /TODAY THROUGH TUESDAY/... SHOWERS CROSSING THE NORTH GA MOUNTAINS EARLY THIS MORNING AHEAD OF A SHORTWAVE MOVING INTO NORTHWEST GA. THESE HAVE BEEN STEADILY DISSIPATING AND SHOULD CONTINUE TO DO SO AS THEY MOVE OFF THE HIGHER TERRAIN INTO METRO ATLANTA. THUNDERSTORMS SHOULD BE RATHER LIMITED THIS AFTERNOON AND EVENING AS THE STRONG SUBTROPICAL RIDGE TO OUR WEST BUILDS MORE STRONGLY INTO GA TODAY. WE REMAIN IN NORTHWEST FLOW ON THE EASTERN PERIPHERY OF THIS HIGH THROUGH TUESDAY...SO ONE OR MORE OF THE WEAK SHORTWAVES MIGHT STILL ENHANCE SHRA/TSRA COVERAGE AT TIMES. THE GFS HINTS AT ONE SLIGHTLY STRONGER SHORTWAVE AND PRECIPITABLE WATER CLIMBING BACK TO NEAR 2 INCHES ON TUESDAY THOUGH THE ECMWF DEPICTS A STRONGER RIDGE AND LESS RAIN CHANCES. THUS...BROAD BRUSHED 20-30 POPS. THE REAL STORY CONTINUES TO BE THE HEAT...WITH NO END IN SIGHT TO THE HEAT ADVISORIES AND EXCESSIVE HEAT WARNING. MAINTAINED CURRENT LAYOUT ADVISORIES/WARNINGS FOR NOW...BUT WILL LIKELY HAVE TO ADD PORTIONS OF NORTH GEORGIA INTO THE ADVISORY MIX ON MONDAY. NEARLY THE ENTIRE AREA ASIDE FROM THE MOUNTAINS COULD SEE 105-110 HEAT INDICES OR GREATER BY TUESDAY. LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... NOT MUCH CHANGE TO OUR HOT AND HUMID CONDITIONS AS THE MID/UPPER TROPOSPHERIC RIDGE REMAINS PARKED OVER THE DEEP SOUTH FROM ARKANSAS TO GEORGIA. PROBABLY THE MOST INTERESTING FEATURE OF THE EXTENDED IS THAT THERE SEEMS TO BE A GROWING CONSENSUS IN THE GLOBAL MODELS TOWARD DEVELOPING A TROPICAL DISTURBANCE WHICH IS NOW CROSSING THE CENTRAL TROPICAL ATLANTIC OCEAN. AS LONG AS THE RIDGE REMAINS SO STRONG OVER US...WE PROBABLY WOULD NOT HAVE ANY IMPACT LOCALLY...THOUGH IT WILL BE SOMETHING TO WATCH OVER THE COMING WEEK OR MORE. 07 AVIATION... 18Z TAF DISCUSSION... MIXTURE OF MOSTLY VFR AND SCATTERED MVFR CONDITIONS EXPECTED TO CONTINUE ACROSS THE FORECAST AREA THROUGH 06Z. ISOLATED CONVECTION ALREADY BEGINNING TO DEVELOP...AND THIS TREND SHOULD CONTINUE...

ISOLATED TO SCATTERED IFR VISIBILITIES ALSO EXPECTED BETWEEN 10Z AND 14Z. SCATTERED MVFR TO IFR CEILINGS ALSO POSSIBLE BETWEEN 10Z AND 14Z...MAINLY IN EASTERN AND SOUTHERN PORTIONS OF THE FORECAST AREA. WINDS WILL BE QUITE VARIABLE OVER THE AREA THROUGH 15Z AS THE LOW LEVEL PRESSURE GRADIENT REMAINS FAIRLY LOOSE. WEST THROUGH NORTHWEST WINDS WILL BE FAVORED THIS AFTERNOON...ESPECIALLY FROM THE ATLANTA AREA NORTH AND WEST. WINDS WILL TREND TOWARD EASTERLY OVERNIGHT...
