• Numerous poles snapped and in process of being replaced.
• Tree uprooted and pointing west. Mobile roof and wall damage. Debris blocking road.

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 81 mph traveled along an 8 mile path. This was the third in a series of tornadoes from a supercell. This tornado touched down on the north side of Oronogo, Missouri near the intersection of County Road 225 and Highway 96 and caused an intermittent path of varying tree damage northeastward before lifting near the intersection of County Road 160 and Nutmeg Lane. There was no apparent damage to structures.

29 minutes of warning. NWS SGF issued a tornado warning for this county at 00:54 UTC, 29 minutes before the tornado touched down, in force until 01:45 UTC.

The county was under a tornado watch, issued at 20:36 UTC and running to 02:46 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 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 00:57 UTC.

34 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.
