EF0 tornado in Livingston County, Illinois

Based on video evidence, a brief EF-0 tornado occurred just north of Pontiac. Surveillance video shared by a property owner showed a clear circulation with multiple sub-vortices on a quarry lake just west of 1600 East Road, north of old US-66. The tornado was observed in storm chaser videos crossing old US-66 just south of North Creek. Damage along the path of the tornado included the removal of a roof to a boat house and damage to a dock, garage, and fence. The maximum width of the tornado of 175 yards was estimated from the aforementioned surveillance and storm chaser videos. Peak winds were estimated at 75 mph.

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.
