With ample deep moisture persisting across the region, strong afternoon heating aided by a weak upper-level trough resulted in numerous strong thunderstorms across north Georgia with isolated reports of severe thunderstorms producing damaging wind gusts.  Heavy rainfall amounts occurred in portions of north and central Georgia, generally in the northeast Georgia mountains, and in the greater Columbus area. In these locations, rainfall amounts of 3 to 4 inches were common, with isolated higher amounts to 5 inches in the mountains, which produced isolated flash flooding and exacerbated flooding from the previous day.
