EF0 tornado in Morgan County, Illinois

The tornado began near the intersection of US-67 and Old Airport Road and tracked northeast for a little over four miles. It crossed I-72 about three quarters of a mile east of exit 60. Damage from this tornado was mainly confined to tree branches along its path, but it produced minor roof damage to a farm outbuilding along south Finch Road and destroyed an open-air farm outbuilding along Massey View Road. The tornado ended just north of the Diamond Grove Cemetery.

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.
