The episode as NWS FFC wrote it up.
Compared to the previous day, August 17th, this was a minimal day for severe weather. However, northwest flow aloft combined with residual moisture and a weak stalled front across north Georgia to generate isolated afternoon and evening thunderstorms, mainly across west and central Georgia. A couple of these became severe producing hail and damaging winds.
