Hail and Damaging Winds in Georgia, August 27, 2010
The upper trough that had lingered across the northeast and mid-Atlantic region was moving out and a large vertically stacked high pressure area was rapidly replacing the trough across the northeast and mid-Atlantic. During the next few days, this high pressure area would drift south toward Georgia, finally shutting off the incessant thunderstorm activity.

What happened
The episode as NWS FFC wrote it up.
The upper trough that had lingered across the northeast and mid-Atlantic region was moving out and a large vertically stacked high pressure area was rapidly replacing the trough across the northeast and mid-Atlantic. During the next few days, this high pressure area would drift south toward Georgia, finally shutting off the incessant thunderstorm activity. However, deep tropical moisture lingered along and south of a stationary front, that during the early morning was draped west-to-east across north central and northeast Georgia. The front served as a focusing mechanism for persistent redevelopment of thunderstorms. Two rounds of thunderstorms, several severe, plagued the area on August 27th. The first occurred across north central and northeast Georgia, near Atlanta and Athens, during the early morning hours between midnight and 4 am EDT. The second round occurred during the mid to late afternoon mainly across east central.
