Severe storms and tornadoes swept across northern Illinois, including an EF2 tornado that caused extensive damage in Stephenson County. No deaths were reported, but extensive damage was caused across rural communities. The National Weather Service confirmed at least six tornadoes, including EF1-rated tornadoes in Harrison, Roscoe, rural Livingston County, Gibson City and Buckley. Lena, a village of almost 3,000 people, sustained the most extensive damage, with three houses losing their entire roof structure and two homes sustaining partial exterior wall collapses. The tornado began as an EF1 and gained strength to an EF 2 tornado, which caused significant damage to trees and power poles. West Carroll Superintendent Heidi Deininger responded to criticism about the district's decision to attend a music contest at the time of the tornado.
