Unstable northwest flow aloft continued to strengthen across the region in response to a vigorous upper low moving through the Great Lakes and the gradual retrogression of the strong subtropical ridge into Texas.  This combined with the continued hot, humid air mass in place across the region and numerous outflow boundaries from overnight upstream thunderstorm activity in the Tennessee Valley supported scattered afternoon and evening thunderstorms throughout north and central Georgia.  In fact, this ended up being one of the more significant convective days for the region for August 2011.  Several of the storms became strong to severe with damaging downburst winds and producing penny to nickel-sized hail.
