Showers and thunderstorms developed across northeast Missouri, west central Illinois, and extreme southeast Iowa between 4 and 11 PM, Wednesday, May 22. Storms quickly intensified after 6 PM, with many severe thunderstorm and tornado warnings issued. An EF-1 tornado was surveyed in Hancock county IL with these storms.

A brief EF-1 tornado hit a farmstead west of Basco in Hancock County Illinois during the evening of May 22nd. A barn was completely destroyed and a large tree was uprooted. The tornado continued for about a half mile before snapping a power pole and then lifting. The tornado was embedded in a larger swath of straight line winds, also estimated around 100 mph, that snapped trees and power poles and damaged outbuildings.

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.
