The lone F3 tornado occurred in Massac county Illinois, near Metropolis, around 330 pm on September 22nd. The tornado injured 2 people, tossed several vehicles up to 100 yards, blew the walls and roof off of a log home, uprooted hundreds of trees, damaged power poles, and destroyed four mobile homes.

The large number of tornadoes during 2006 came on the heels of drought conditions the year, when only 19 tornadoes were reported in Illinois. A very mild winter and an active storm track across Illinois in March and April set the stage for an early start to the record setting tornado season in the state.

Ten of the tornadoes were in northeast and north central Illinois including 4 in Iroquois County, 2 in Ford County, 1 in LaSalle County, 1 in Kankakee County, 1 in Livingston County, and 1 in Cook County. They were all F0 and F1 tornadoes. The Cook County tornado was an F0 that occurred on the north side of Chicago at Loyola University on September 22.
