July stands out as the peak month for tornado activity in the area, with 43 tornadoes recorded during that month since 1950. This aligns with typical summertime severe weather patterns across the Midwest, when warm, humid air masses collide with cooler systems to produce the atmospheric instability necessary for tornadic thunderstorms. The widest tornado on record occurred on June 13, 1976, an F4 that reached an extraordinary 1,760 yards in width while traveling 3.3 miles and causing two fatalities. More recently, an EF1 tornado on July 16, 2024 set the record for longest path length at 29.1 miles, though it caused no injuries or property damage.
The most recent tornado near Tinley Park touched down on March 19, 2025, rated EF0 with a brief 0.3-mile path and 90-yard width, causing no damage or injuries.
