On the evening of May 2, 2018 strong thunderstorms moved out of Kansas and into western Missouri. These storms formed squall line tornadoes, that did damage across portions of the Kansas City Metro Area. The bulk of the damage occurred in Jackson County, Missouri, where several trees were destroyed in the Raytown area near and along Raytown Road. Two tornadoes occurred that night in Raytown causing a narrow path of tree damage, which also caused some structure damage. Several other areas had some tornado and wind damage, although not quite as extensive. Several areas had trees blown down with some damage done to objects they fell onto.

As a line of severe thunderstorms pushed through the area, it produced several tornadoes. One of these tornadoes produced damage to large threes, which fell onto houses, causing roof and structural damage. The most notable of these damages occurred in Raytown where a house was significantly damaged by a large fallen tree. There were no injuries reported from these storms.

A line of severe thunderstorms produced several tornadoes, one of which impacted neighborhoods of Raytown. The extent of the damage was to large trees, some of which fell onto houses, causing some roof and structural damage.

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 00:52 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.
