What happened

The episode as NWS ILX wrote it up.

Low pressure tracking along a stationary frontal boundary near the I-70 corridor brought widespread strong to severe thunderstorms to much of central and southeast Illinois during the late afternoon and evening of April 29th. A tornado briefly touched down in an open field northeast of Alexander in Morgan County. Elsewhere, thunderstorms packed winds of 60-70mph and caused significant wind damage. A downburst with estimated winds of 80mph caused property damage of around 2 million dollars in Middletown in Logan County. In addition to the strong winds, many of the storms dropped copious amounts of rain, causing widespread flash flooding. Numerous roads were closed due to high water, including Highway 29 north of the McClugage Bridge in Peoria where a mudslide occurred.
