44 damage points were recorded along this path by NWS PAH, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 135 mph.

• Several cars blown up to 100 feet with one flipped around.
• 2 barns/garages with metal roofing and shingles partially blown off.
• Fencing blown over. Eyewitness report (public) of tornado sighted.
• At least a dozen trees with broken branches, some large.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

An outbreak of severe thunderstorms and tornadoes occurred across western Kentucky. Most of the severe weather was along and south of a Paducah to Madisonville line. North of that line, serious flash flooding resulted in a fatality. A surface low pressure center tracked rapidly north-northeast from Arkansas to the upper Mississippi Valley, dragging a warm front north across western Kentucky. Instability was adequate for tornadoes and severe storms in the presence of very strong wind shear. A very moist air mass resulted in heavy rainfall, which produced localized flash flooding due to the water-logged ground. Locally 5 to 6 inches of rain had fallen over the previous week. Rainfall rates in these thunderstorms were locally one-half to one inch per hour.

The path of this EF-0 tornado started on the west side of the Pennyrile Parkway, then moved northeast across Lake Morris. At least four barns or sheds were damaged, primarily due to partial loss of roofing and siding. One camper trailer was overturned. Limbs were broken off hundreds of trees. Some trees were uprooted. There was one eyewitness account of the tornado near the start of the damage track. The track ended on the northwest side of Highway 107. Peak winds were estimated near 85 mph.

This brief EF-0 tornado touched down along Highway 189 about a mile west of the Todd County line. Two garages or farm buildings sustained minor roof damage. A few tree limbs were broken. There was one eyewitness account of the tornado. Peak winds were estimated near 65 mph.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 21:16 UTC and running to 03:23 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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 00:42 UTC.

29 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.
