A deepening low pressure system moved northeast from Arkansas along a warm front that extended across southeast Missouri and southern Illinois. Surface dew points were in the upper 50's to lower 60's along and southeast of the warm front. A strong upper level trough over the western Plains produced a strong southwest flow of 60 to 80 knots at 500 mb. Winds at 850 mb were south to southwest around 40 knots.

Countywide, a total of 69 homes were destroyed and 203 were damaged. Of the 203 damaged homes, 56 sustained major damage. Most of the damage occurred in the communities of Greenville and Powderly, where 48 homes were destroyed and 32 sustained major damage (35 to 40 percent were mobile homes). The primary focus of attention was where the fatalities occurred at a mobile home park on U.S. Highway 62 near the Highway 189 bypass. In the Muhlenberg Industrial Park, a spec building was flattened and another building was heavily damaged. A half dozen businesses and churches were damaged, including a hotel and a car dealership. The Western Kentucky Parkway was closed near Central City due to trees blocking the road. A utility pole fell on a vehicle travelling on Kentucky 601. The tornado passed within a short distance southwest of a high school, where a basketball game was in progress at the time of the storm. A large portion of the gym roof was damaged, causing heavy water damage due to rainfall entering the building. The National Guard was activated to provide security for the area. The county was declared a federal major disaster area. The average path width was 325 yards. Peak winds were estimated near 160 mph.

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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:48 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.
