The episode as NWS FFC wrote it up.
A cold front an upper-level trough were approaching the area from the northwest. While the air mass across north and central Georgia had been relatively dry and stable for several days, low-level moisture was on the increase in advance of the front. In addition, the remnants of Tropical Storm Hermine had become caught in the upper-level trough and front and contributed to an increase in thunderstorm activity across the region on this day. A few of the storms became strong to briefly severe in north Georgia during the late afternoon and evening hours.
