The episode as NWS FFC wrote it up.
The ever persistent pattern of the 2011 summer continued across the United States. A very strong subtropical ridge, centered across Texas and the southern plains, remained in place. This continued to place Georgia and the southeastern U.S. in an active, unstable northwest flow aloft. Isolated to scattered thunderstorms developed during the afternoon once again. The activity was mainly confined to far north and northeast Georgia on this day. Coverage was minimal, but the few cells that did develop became strong and produced strong downbursts. While not meeting local severe criteria, a few trees were blown down on roads and homes in Walker and Whitfield counties of northwest Georgia.
