A surface low across the Lower Mississippi Valley began to lift north toward the Tennessee Valley on the 1st, dragging a front that was stationary across central Georgia north toward the mountains.  With weak to moderate instability and abundant gulf moisture in place, widespread showers and scattered thunderstorms developed along the front.  One of these storms became severe in Banks County, with downed trees reported.  However, as the severe thunderstorm potential weakened into the evening,  training showers and a few thunderstorms with heavy rain developed from Zebulon and Griffin to Lawrenceville and Gainesville to Helen. Storm total rainfall amounts from 3 to 6 inches with isolated 8 inches occurred during the night which caused flash flooding and river flooding.
