Illinois leads the nation in the number of tornadoes so far this year with 86. There were 22 confirmed tornadoes alone across the state during a March 31 outbreak which killed several people. State climatologist Trent Ford says the peak time in Illinois for tornadoes is April through June, but this year has been different.
Between 1950 and 2020, April has been the deadliest month for tornadoes with 97 reported deaths, with most coming from the 1967 Oak Lawn tornado outbreak. The second deadliest month was August, with 29 deaths associated with the 1990 Plainfield tornado.
