An upper-level disturbance moved across the Deep South in the early morning hours of April 5, 2022. This fostered the development of a surface low which moved across Central Mississippi and into North Alabama. Thunderstorms in the morning initially posed a threat of large hail and damaging winds. Later in the morning and into the afternoon, storms became more surface-based and a tornado threat resulted, mainly impacting the southern and southeastern portions of Central Alabama. On April 6th, a strong cold front moved through Alabama, producing another round of severe thunderstorms, but no tornadoes.

National Weather Service meteorologists surveyed damage in western Chambers County and determined that it was consistent with an EF0 tornado, with maximum winds near 80 mph. A brief weak tornado touched down near County Road 33 where an outbuilding was damaged with sheet metal blown downwind. Otherwise, some trees were snapped and uprooted along the short path of the tornado.

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:29 UTC.

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.
