The episode as NWS FFC wrote it up.
The eastern U.S. upper trough noted on the 26th of September continued to evolve into a deep upper low across the southeast U.S. with an associated pocket of cold temperatures aloft. Temperatures aloft at 500mb were near -20C during the late afternoon and early evening hours of September 27th. As the preceding area of rain and thunderstorms exited the area to the east during the afternoon, cloudy conditions across north and west Georgia gave way to partly sunny skies. This allowed temperatures to warm into the low and mid 80s across the region. The warm surface temperatures created a very unstable environment as the upper low and cold core pocket rotated across the region. Scattered to numerous thunderstorms developed across north Georgia, with lesser coverage of convective activity across central Georgia. Only the southwest part of the county warning area managed to escape the afternoon thunderstorms. The thunderstorms were fast moving, but several produced damaging downburst winds and penny to occasionally golf ball-sized hail. A strong shower on the tail end of the convective activity (no lightning observed) even produced a brief tornado in Laurens county in southeast Georgia. The severe weather event only lasted a couple of hours in the 530 pm to 730 pm time frame.
