A surface low tracked northeast across northern Mississippi and northwest Alabama Saturday afternoon and evening. An upper level disturbance moving out of the southwest United States providing ample lift and shear increased as the surface low deepened. The frontal system progressed slowly eastward, and this allowed for widespread rainfall amounts of 2 to 4 inches.

National Weather Service Meteorologists surveyed damage in Sumter County and confirmed a weak tornado. The tornado touched down just west of Pretty Branch Road along the Norfolk Southern Railroad, about 0.5 miles east of Cuba. The tornado tracked northeast downing several large hardwoods and caused damage to the roof and anchoring system of a manufactured home as it crossed Pretty Branch Road and the railroad track. The tornado moved parallel to the railroad track downing approximately one dozen trees. The tornado lifted just west of Old Livingston Road.

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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 19:58 UTC.

13 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.
