Southerly winds brought rich moisture into the area this weekend ahead of a storm system over the midwest to midsouth states. With rain and clouds to the north and clearing skies to the south, a strong stationary front developed over north Georgia from near LaGrange to south of Augusta. Severe storms developed in the early afternoon along this east-to -west oriented front and tracked east, tapping into the warmer, more unstable air to the south. Some of the storms produced large hail up to golf ball size and wind damage. The storms produced two tornadoes - one near Moreland (Coweta County) and another near McDonough (Henry County).
