After over a week of near-record to record high temperatures, several upper-level disturbances followed by a strong upper-level low pressure system produced multiple rounds of severe weather across Central Alabama. This system was characterized by strong upper-level winds and very cold upper-level temperatures. The first round produced one brief, weak tornado in St. Clair County on the evening of January 19. The second round occurred on the morning of January 20 with 12 tornadoes across Marengo, Elmore, Macon, Lee, Pike, and Barbour Counties. A third round produced damaging straight line winds on the night of January 21, including in the Birmingham metro area where the Birmingham airport measured a 75 mph wind gust and in Oneonta where 80 mph straight-line winds caused significant damage. A brief tornado also occurred in Tuscaloosa County with this activity. Finally, a fourth round moved through during the day on January 22 with 3 tornadoes across Bullock and Lee Counties.

National Weather Service meteorologists surveyed damage in southwest Lee County and determined that the damage was consistent with an EF0 tornado, with maximum sustained winds near 70 mph. A tornado formed along CR 14 just south of I-85 where a few small pine trees were uprooted and some large branches were broken. The tornado continued northeast, crossing I-85 near Beehive Road and Cox Road, peeling back half of the roof of a mobile home at the Windover Farm mobile home park. It crossed Veterans Boulevard and then caused shingle damage to multiple apartment buildings near Longleaf Drive while breaking tree branches. The tornado dissipated as it crossed Alabama State Road 267 near the southwest boundary of the Auburn University campus.

National Weather Service meteorologists surveyed damage in central Lee County and determined that the damage was consistent with an EF1 tornado, with maximum sustained winds near 95 mph. The tornado touched down along Cunningham Drive, just northeast of the Auburn-Opelika Airport and tracked northeast. Minor damage occurred at touch down but increased as the tornado approached Pepperell Parkway, where numerous trees were snapped or uprooted and some homes suffered damage. The tornado lifted near Northgate Drive and Oak Bowery Road.

12 minutes of warning. NWS BMX issued a tornado warning for this county at 19:48 UTC, 12 minutes before the tornado touched down, in force until 20:15 UTC.

The county was under a tornado watch, issued at 17:56 UTC and running to 20:45 UTC.

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 19:56 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.
