Thunderstorm Wind in Winnebago County, Illinois

A public report was received of roofing and siding damage, solar panels peeled back from a roof, and 12 inch diameter trees snapped northeast of Pecatonica. Time estimated using radar.

Scattered severe thunderstorms produced numerous tornadoes and large to giant hail as they moved across northern Illinois during the late afternoon and evening of March 10th. Included in the 9 total tornadoes in northeast Illinois that day is an EF-3 which tracked from the south side of Kankakee into Newton and Jasper counties in Indiana and devastated a portion of Aroma Park. There were two primary corridors of large hail; one extending from northern Will County into the city of Chicago, which produced hail upwards of 4.8 inches in diameter, and another from central Livingston County extending east across Kankakee County. Nearly a dozen individual reports of hail greater than 4 inches came out of this southernmost corridor, and a 6.6 inch hailstone found in Kankakee is pending as the new Illinois state record.
