Episode Narrative: A hot, very moist, tropical air mass remained in place across the region. The persistent subtropical ridge had shifted just to the southeast of Georgia. A cold front was near the Georgia-Tennessee border. The front, when combined with daytime heating and the very unstable, hot air mass, provided the necessary lift for widespread and numerous showers and thunderstorms. It turned out to be the most active day for severe thunderstorms during the month of July. Many of the storms produced damaging downburst wind gusts, marginally severe hail, and excessive cloud-to-ground lightning. Flash flooding was also observed with a couple of the storms. One early morning isolated storm over Coweta county, just southwest of Atlanta, produced three to four inches of rain in a couple of hours as it persisted over the same areas near Newnan in the very early morning hours after midnight.
