A deep upper trough was moving from the mid-south toward the southeast U.S. early on the 26th. A strong cold front accompanied the upper system. A squall line of thunderstorms developed after midnight on the 25th across Mississippi and Alabama and reached the Georgia/Alabama border around 5 am EST. The line of thunderstorms intensified and bowed out just as it was moving in Georgia during the early morning hours. Wind gusts in excess 60 mph affected many counties as these thunderstorms rolled through the area during the early morning hours, causing extensive wind damage to trees, power lines, and some structures from the west and northwest side of Atlanta toward the Alabama border. In addition, two tornadoes, one an EF3, developed along the stronger part of the line as it moved through Carroll county before daybreak causing extensive damage along their paths.

A survey conducted by The Weather Channel concluded that a very brief EF0 tornado touched down near Lassiter High School, about five miles northeast of Marietta, or near the intersection of Mountain View School Road and Sims Drive, just east of Trickum Road and Shallowford Road. Convergent tree rotation was observed in this area, which otherwise was embedded within a nine-mile long path of damage that extended from the Canterbury Woods Country Club on the west to just north of Roswell on the east. The damage path for this tornado was about one-half block long and 20-yards wide. Extensive damage to trees and homes was noted in the area.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 05:47 UTC.

7 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
