Episode Narrative: A deep upper-level trough was shifting slowly east from the central U.S. into the eastern U.S. A leading cold front was located from New York to Alabama. A summerlike subtropical ridge across the southeast U.S. was slowly shifting off the southeast U.S. coast. The highly meridional flow had allowed an unusually deep tropical air mass to spread far northward across the eastern half of the U.S. This weather system had been responsible for widespread catastrophic flooding in western and middle Tennessee during the previous three days. As the system moved toward Georgia, it began to weaken considerably and the main dynamics lifted northeast more toward the mid-Atlantic. Nonetheless, the slow movement of the system brought several rounds of showers and thunderstorms to the area with two-day rainfall of 3-4 inches. Flash flooding was observed in several counties on the northwest and west side of Atlanta, some of the same counties that experienced catastrophic flooding during late September 2009. Flash flooding during this event was far less significant. Severe weather was isolated and confined to east central Georgia toward the end of the event on the 3rd. A deep upper-level trough was shifting slowly east from the central U.S. Event Narrative: The Times Herald of Newnan reported that lightning struck the electrical line of a home in the Arnco community causing a fire. Two rooms of the wood home suffered extensive damage from the fire. The remainder of the home suffered smoke damage. The Marietta Daily Journal reported that a few trees were blown down in the vicinity of Whitlock Avenue, McDonald Street, and near the town square. At least one tree was down on a power line causing a power outage to approximately 3000 residents in the area. The Times Herald of Newnan reported that a 7000 square foot home was struck by lightning. The lightning ran through the electrical lines of the home and ignited some cardboard boxes stored near an electrical outlet. The fire was confined to one room.
