Episode Narrative An unusually strong late summer cold front was moving toward the southeast United States supported by strong northwest flow aloft on the east side of an ever persistent strong subtropical ridge across Texas and the southern plains. With an unstable, hot surface environment in place across Georgia, the stage was set for scattered thunderstorms. Activity was a little more widespread than on previous days. The storms exhibited frequent cloud-to-ground lightning. A few became strong to severe producing penny to nickel-sized hail and damaging downburst winds.
Event Narrative The Meriwether County Emergency Management Director reported that at least a dozen trees were blown down in the north central part of the county around Rocky Mount. WSR-88D base velocity data clearly showed a downburst in this area. A few power lines were down in the area as well.
