Tornado in Scott County, Illinois

Sentinel satellite data showed a narrow tornado touched down in a farm field north of Montezuma Road and east of county road 600E. It moved northeast for approximately one mile, producing crop damage. The tornado lifted before reaching Big Swan Road. No structures or tree damage was noted, so this tornado was assigned a rating of EF-U.

A mesoscale convective vortex, or MCV, moved into central Illinois late on the morning of Wednesday, June 18th. Moderate instability developed ahead of this feature, and as scattered storms formed they quickly obtained rotation due to shear from the MCV. A total of 14 tornadoes occurred within the NWS Central Illinois county warning area, mainly west of I-55. One minor injury occurred when winds associated with a tornado tossed a woman against her home in Morgan County. Across eastern Illinois, a line of storms developed during the afternoon, mainly producing wind damage before shifting east into Indiana. A wake low developed after the MCV passed, resulting in a short period of non-thunderstorm wind gusts, generally between 45 and 55 mph. The highest non-thunderstorm wind gust associated with the wake low was 58 mph.
