Hail in Forsyth County, Georgia

Several reports of large hail were received from north central and northeast Forsyth county. The public reported two inch-diameter hail two miles south of Chestatee and penny to quarter-sized hail northeast of Cumming near the intersection of Georgia Highway 400 and Georgia Highway 20, and on Georgia Highway 369. Nickel-sized hail was observed just west of Lake Lanier near the intersection of Georgia Highways 53 and 300. Finally, Forsyth County Fire and Rescue Services observed quarter-sized hail near Cumming.

The pattern that began to evolve on March 14th continued and intensified on March 15th. A stationary front remained draped across north Georgia from near Atlanta to Athens. South of this front, the air mass was becoming increasingly warm, moist and unstable. Meanwhile, aloft, a low amplitude, yet vigorous short wave embedded within a fast zonal flow, was tracking rapidly eastward from the mid south into the southeast. Strong shear and high helicity combined with the unstable air mass and the frontal boundary to allow repeated severe thunderstorms to develop and track eastward along the boundary across north Georgia. The activity began early in the day as a complex of thunderstorms moved into the area from Alabama and continued until nearly midnight. As the day progressed, especially during the afternoon, the development of the activity gradually progressed further south and by midnight had reached the south and southeast parts of the state. Numerous severe thunderstorms and tornadic supercells were observed throughout the day.

Historical records indicate that this was one of the most significant severe weather days for the Peachtree City Weather Forecast Office with more events and warnings than had been observed since May 2003.
