Severe Weather in North & Central Georgia
October 25-27, 2010

From October 25th through the 27th, 2010, a very active weather pattern set up over Georgia. The severe weather began early on Monday as a strong upper level disturbance in the Mississippi valley tracked across north Georgia. With the abundant Gulf moisture that was pumped across the state from the southerly flow and the decent instability and shear values (CAPE values were around 1000 J/kg and 0-6 km shear values were over 40 knots), the environment was primed for thunderstorms with the possibility of some to become severe. As the storms tracked across north Georgia before dawn Monday, October 25th, numerous damage reports were relayed to the National Weather Service in Peachtree City. Much of north Georgia saw trees and power lines down from strong thunderstorm winds and up to golf ball sized hail was observed. In Walker county, schools had to be delayed two hours due to the wind damage and power outages across the county. In addition, at 5:22 am, a fast moving EF1 tornado, with winds of 100 mph, was reported in the southern part of Rising Fawn in Dade county. The damage path of the tornado was approximately 2.5 miles with a maximum path width of 150 yards. Thirty homes received minor roof damage and 100-200 trees were downed. In addition, two barns were destroyed and a mobile home had most of its roof ripped off.

Another tornado was observed in Ringgold at 5:52 am, October 25th. This EF0 tornado, with winds of 80 mph, produced a damage path 300 yards long and 75 yards wide. Approximately 50 trees were downed or suffered extensive damage. Two homes, two chicken houses and a barn received minor roof damage.

Storms on Monday, October 25th developed later in the afternoon across central Georgia. Golf ball sized hail was observed with these storms and several trees were reported downed.

Although strong storms continued across north Georgia on Tuesday, October 26th as a cold front approached the state later in the day, only minimal reports of severe weather were received, including golf ball sized hail in White county. This slow moving cold front was still situated across north Georgia on the morning of the 27th. On the 27th storms again moved across north Georgia and into south Georgia later in the day and overnight. Although all of the reports of hail were below severe criteria (1 inch), numerous reports of downed trees were reported, including some blocking roadways. In addition, a storm survey conducted by the Cherokee County Emergency Management revealed an EF0 tornado, with winds of 75 mph, in Cherokee county. The tornado had a path length of 0.75 miles and a width of 75 yards. Three homes sustained major damage and ten homes received minor damage. Three outbuildings and three cards were destroyed by downed trees.
