EF2 tornado in Knox County, Illinois

A tornado touched down 4.5 miles west-northwest of Yates City in eastern Knox County then tracked southeastward to the Knox-Peoria County line. Large tree limbs were snapped and crops were scoured in numerous places along this path. A house had the roof torn off and much of the upper level of the structure severely damaged. The attached garage was also destroyed. In addition, a large garage was destroyed, and seven outbuildings were severely damaged. The tornado continued southeastward into Peoria County.

A stationary frontal boundary extending from southern Michigan across north-central Illinois served as the focus for severe thunderstorm development during the late afternoon and evening of June 5th. A vigorous upper-level disturbance tracking across the Upper Midwest added extra wind energy to the atmosphere, allowing supercell thunderstorms to develop along the front. Eight tornadoes were spawned by the storms, mainly along a Galesburg to Eureka line. An isolated tornado formed further south across eastern Logan and western DeWitt counties as well. No injuries were reported.
