EF3 tornado in Marshall County, Illinois

This tornado crossed from Woodford County into Marshall County just west of Snag Creek Road at 5:02pm CDT. It strengthened to peak intensity with maximum estimated winds of 155mph across rural Marshall County northwest of Washburn. A log house had all of its walls collapsed and a nearby home lost its roof and second floor. Severe tree damage occurred, with some trees having only their trunks and large branches remaining. Extensive crop damage was also noted with corn leaves ripped off and plants uprooted. The tornado curved eastward and gradually weakened as it damaged additional trees, outbuildings, and a few roofs before dissipating just west of the intersection of County Road 150 North and County Road 2100 East at 5:15pm CDT.

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.
