The episode as NWS FFC wrote it up.
A weak upper-level low continued to meander about the mid-Atlantic region. A weak cold front was evident from the mid-Atlantic into the southern Appalachians. A warm, humid air mass continued across Georgia. The upper low once again provided the support for scattered thunderstorm development across north Georgia during the afternoon and evening hours. A few of these storms became severe, producing marginally severe hail and damaging wind gusts. Thunderstorms continued to drift south into east central and central Georgia after midnight, but these remained below severe limits.
