Thunderstorms developed late in the evening of July 22nd across northeast Illinois and continued into the morning of July 23rd. Numerous thunderstorms moved over the same areas across portions of Lake County, producing torrential rain and flash flooding. Large hail also occurred. Three tornadoes occurred in the southern suburbs of Chicago just after sunrise. Additional thunderstorms developed during the morning and continued into the afternoon of July 23rd, producing isolated large hail and wind damage.

A tornado with peak winds of 70 mph touched down along Pinnacle Drive, just north of Renwick Road. A construction camera at Lewis University Airport showed the tornado likely lifted then briefly touched down as it moved south into the Prairie Bluff Forest Preserve south of Renwick Road before lifting again. The tornado touched down again near the Statesville Correctional Center where it caused minor tree damage. The tornado continued moving south across Caton Farm Road and entered a residential area of Crest Hill. A concentrated area of damage including several uprooted trees and numerous broken tree limbs was found in the vicinity of Elsie and Highland Avenues. The tornado paralleled Highland Avenue and Clement Street as it crossed into the far north side of Joliet, where it produced sporadic tree limb damage. Numerous trees were damaged in the Mount Moriah Cemetery and the tornado lifted just southeast of the cemetery.

A brief tornado with peak winds of 75 mph touched down just north of the intersection of Baker Road and Route 52. The tornado moved south along Route 52 producing sporadic tree 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 Slight Risk. The outlook in force was issued at 05:50 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.
