15 damage points were recorded along this path by NWS SGF, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.

• Large tree snapped at the trunk. Debris carried to the northeast.
• Measured 80mph on an anemometer before it broke. Tree is uprooted laying towards northeast. No roof damage to house.

Multiple rounds of storms producing heavy rainfall, severe winds, hail and tornadoes moved across the Missouri Ozarks from May 20th and into the early morning hours of May 24th as upper level disturbances interacted with a slow moving but powerful storm system over the central Plains. Tornadoes occurred with each round, with the strongest and most numerous tornadoes occurring during the late afternoon and evening of the 22nd. On the anniversary of the Joplin Tornado off 2011, another tornado, rated EF-3 struck the north side of Joplin. This storm system eventually produced subsequent tornadoes in Golden City, Eldon and Jefferson City. Unfortunately there were three fatalities as a result of the tornado in Golden City. The cumulative rainfall caused areas of flash flooding with some flooding lingering across the region. Some locations in southeastern Kansas and southwestern Missouri reported in excess of 8 inches of rainfall over the 72 hour period. .

A National Weather Service storm survey determined that an EF-0 tornado with maximum winds of 85 mph traveled along a 1 mile path just north of Fellows Lake. This short lived tornado touched down on the outskirts of Fellows Lake and FR 66 then tracked northeast across FR 193. The roof of a barn was torn off along FR 62, and another small outbuilding suffered minor roof damage along FR 197 before the tornado dissipated north of Highway KK. Minor shingle damage occurred to 5 homes and numerous trees were damaged.

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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:10 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.
