A long-duration severe weather event occurred from the late morning hours of Tuesday, January 3rd to the early morning hours of Wednesday, January 4th. Several rounds of rain and thunderstorms impacted Central Alabama, producing tornadoes, damaging straight-line winds, quarter size hail, and flooding.

National Weather Service meteorologists surveyed damage in eastern Chilton County and determined that it was consistent with an EF1 tornado, with maximum winds near 90 mph. The tornado touched down just west of County Road 190 on the Chilton County side of the Coosa River. Several dozen softwood and hardwood trees were snapped or uprooted. In addition several homes and boat houses sustained roof and siding damage, mainly along County Road 192. The tornado then crossed the Coosa River and into Coosa County.

National Weather Service meteorologists surveyed damage in far western Coosa County and determined that it was consistent with an EF0 tornado, with maximum winds near 75 mph. This tornado originated in Chilton County just west of the Coosa River and crossed into Coosa County where some tree damage was noted on County Road 5 and Hidden Valley Drive. The tornado dissipated near the intersection of County Road 5 and Pelican 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, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:20 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.

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.
