A potent weather system developed and tracked across the Lower Mississippi River Valley during the evening of November 20. This system and associated convective activity resulted storms that produced hail, wind damage, and several tornadoes.

This tornado touched down in the Center Ridge community along county road 87 and tracked northeast for nearly 3 miles. A few trees were damaged and uprooted. Along county road 82, a large section of a chicken house and few other buildings were damaged. A barn was damaged and a mobile home had siding damage and the porch was blown off. Just before the tornado dissipated, two mobile homes had skirting damaged. The tornado lifted just before county road 93. Max winds were 90 mph and width was 200 yards.

31 minutes of warning. NWS JAN issued a tornado warning for this county at 01:38 UTC, 31 minutes before the tornado touched down, in force until 02:33 UTC.

The county was under a tornado watch, issued at 21:52 UTC and running to 04:39 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, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:56 UTC.

12 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.
