Northwest flow aloft persisted across the southeast United States as the result of a large subtropical high anchored over the southern Plains.  A cold front was approaching the area from the northwest.  The front, combined with disturbances in the northwest flow aloft, brought another round of showers and thunderstorms to the area during the maximum heating hours of afternoon and evening. While the thunderstorms remained below severe limits, frequent cloud-to-ground lightning and heavy rain were common in north Georgia.  Some lightning fires were reported, a few trees were blown down, and flash flooding was observed in parts of metropolitan Atlanta.  During the early morning hours of the 13th, a mesoscale convective complex moved southeast out of Tennessee into north central and west central Georgia.  While these thunderstorms were not severe, frequent cloud-to-ground lightning was observed once again, affecting one home shortly after midnight in Floyd county and another in Fayette county around 530 am EDT.
