A vigorous closed upper low continued to move across the mid-latitudes of the U.S. from the western Ohio and Tennessee Valleys to the eastern Ohio and Tennessee Valleys and the Mid-Atlantic.  A deep surface low, associated with the upper low, was moving through the Great Lakes with a cold front extending southwest from the surface low into Oklahoma.  This synoptic pattern prompted repeated development of convective complexes, which traversed the region during this time frame.  A well organized squall line moved into western Georgia from Alabama during the mid-afternoon and traversed much of north Georgia through the early evening.  Widespread damaging winds were observed with this highly organized convective system.
