One of the most memorable tornado outbreaks in Illinois history occurred on April 19, 1996. During the day, 33 tornadoes were reported as supercells erupted and moved across the state during the afternoon and evening hours. Wind estimates in excess of 170 mph were associated with some of the stronger tornadoes, one of which ripped through nearby Ogden, IL.
