EF1 tornado in Vermilion County, Illinois

A tornado touched down along East 1800 North Road west of its intersection with IL-49 about 2 miles west-northwest of Fithian at 7:39pm CDT. It tracked eastward along this road, significantly damaging several outbuildings before entering Kickapoo State Recreation Area where it snapped or damaged an estimated 250 trees with winds of up to 110mph. The tornado continued eastward, then dissipated along Hungry Hollow Road just west of Danville at 7:53pm CDT. Damage in Danville was determined to be from straight-line winds of 80-100mph.

A strong storm system interacted with a highly unstable and sheared environment to produce a significant severe weather outbreak across central Illinois during the late afternoon and evening of June 11th. Scattered supercell thunderstorms initially developed west of the I-55 corridor along a pre-frontal trough during the afternoon. One of these storms produced an EF-3 tornado that impacted portions of Woodford and Marshall counties and dropped tennis ball-sized hail (2.50 diameter). Additional cells rapidly developed further west across southeastern Iowa into northern Missouri ahead of an advancing cold front. These storms congealed into a line and pushed eastward into central Illinois during the evening. Widespread damaging wind gusts of 60-70mph occurred with the line along and north of the I-72 corridor. After storm surveys were completed, it was discovered an additional 8 tornadoes were embedded within the line...creating pockets of enhanced damage.
