A significant late summer upper short wave was diving southeast from the mid-Mississippi Valley toward the southeastern United States.  A convective outflow boundary from overnight convective activity was present across central Georgia.  With ample moisture and continued hot temperatures, scattered to numerous thunderstorms developed quickly during the early and mid-afternoon across central Georgia, roughly from La Grange, to Thomaston, to Augusta southward.  A few isolated stronger thunderstorms were also noted across northeast Georgia during the afternoon.  Several of these thunderstorms became strong to severe producing damaging downburst winds and nickel to quarter-sized hail.  This was probably the most significant severe convective day for the month of August within the WFO FFC county warning area.
