What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado began about one mile west of Warrensburg along North Kenney Road. It was photographed by the fire chief from Warrensburg as it approached town. The tornado produced roof damage to several homes and damaged numerous trees in Warrensburg. It then traveled along west Illiniwick Road, snapping a couple of large trees before dissipating about a half mile east of north Wyckles Road, which was about 2.5 miles east of Warrensburg.

The wider storm

A slow moving frontal system aided the development of supercell thunderstorms by mid-afternoon, which eventually grew upscale into a line segment as they progressed across central and southeastern Illinois during the evening. A total of four tornadoes occurred across Logan and Macon counties in central Illinois. One injury occurred in Logan County when a semi-truck was blown over by one of the tornadoes. In addition to the tornadoes, scattered wind damage also occurred.

Began near Warrensburg (39.9300, -89.0900).
