Another strong short wave and surface cold front, associated with the large and deep upper-level trough over the central U.S., swept through the region bringing more scattered severe thunderstorms and isolated tornadoes to north and central Georgia.

A National Weather Service survey team found that an EF1 tornado with maximum wind speeds of 95 MPH and a maximum path width of 440 yards touched down in a residential section of southeast Vidalia between Laurel Drive and Maple Drive. The tornado moved east-northeast crossing Highway 280 where it damaged the roofs of several businesses bent a large flag pole near Brantley's Marine and Guns. The tornado continued moving east-northeast snapping or uprooting numerous trees until ending just north of the city of Lyons along U.S. Highway 1. No injuries were reported.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

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 Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:51 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

26 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.
