EF0 tornado in Rockdale County, Georgia

A survey conducted by the National Weather Service in Peachtree City, Georgia confirmed that the EF2 tornado, which originally touched down in northeast Clayton county and then tracked across northern Henry county, continued into southern Rockdale county and then into western Newton county before finally lifting. The tornado entered Rockdale county just north of Union Springs and tracked east-southeast toward the city of Magnet on the Newton county line. The tornado weakened to an EF0 as it entered Henry county and continued as an EF0 across Rockdale and Newton. Damage was confined to an intermittent tree and power line damage along the tornado track, much of which occurred along or near Georgia Highway 212 and Oglesby Bridge Road where from 10 to 20 trees were down. No structural damage was reported from this tornado within Rockdale county.

A stationary front was draped across north Georgia early on May 10th with an active northwest flow aloft. Meanwhile...a vigorous short wave aloft was approaching the area from the southern plains. The stationary front provided the focus for two rounds of showers and thunderstorms, one early in the morning on the 10th and another in the afternoon. The activity tracked east-southeast with the upper flow aloft, mainly across north Georgia during the early morning and across central Georgia during the afternoon. An isolated strong supercell also tracked across the southern part of central Georgia during the evening. After a lull of convective activity for about four hours, intense multicell thunderstorms tracked into the area from Alabama after midnight and before dawn on the 11th. As these thunderstorms tracked across west central and central Georgia, 15 tornadoes were identified by subsequent surveys making this the most significant tornado outbreak to affect the area since the Katrina-associated tornadoes on August 29, 2005. Millions of dollars of property damage were reported as many homes were destroyed from these tornadoes from the western and southern suburbs of Atlanta southeastward across Macon, Dublin, and other counties in east central and southeast Georgia. Many of these counties were eligible for disaster assistance from the federal government.

In addition to the tornadoes and thunderstorm winds that caused extensive damage in dozens of counties across north and central Georgia during the early morning hours of May 11th, strong gradient winds developed on the back side of the strong cold front that moved through the area as low pressure intensified across the mid-Atlantic region. The strong winds combined with wet ground resulted in dozens of trees being blown down in some north Georgia counties. There were also two deaths as a result of downed trees in Barrow and Gwinnett county, all non-thunderstorm-related winds.
