A weak upper-level trough remained evident across the eastern U.S., immediately to the west of the East Coast while a strong subtropical ridge remained anchored across the central and southern Plains.  A residual convective outflow boundary was evident across east Georgia, with a notable afternoon seabreeze in the southeast part of the state.  Thunderstorms developed during mid-afternoon across central Georgia and the northeast mountains.  Numerous outflow boundaries allowed the thunderstorms to continue to develop and propagate erratically across north and central Georgia well into the evening hours thanks to a continued hot, humid air mass in place.  By far on this day, the most notable concentration of convective activity was across the eastern portion of the state.
