August 21, 2026 DePue-Hennepin Tornado

Typical late summer weather is expected this week with low chances (10-30%) for showers and thunderstorms, late tonight through Wednesday morning. Much of the area will likely remain dry and sunny through late in the workweek.

A slow moving EF0 tornado, with peak winds of 80 MPH, developed along the southern banks of the Illinois River and moved towards the east-southeast. The tornado crossed through a rock quarry where it tipped over a portion of an industrial conveyor system. The tornado then turned more south-southeast and gradually weakened, producing sporadic tree damage along an intermittent path before completely dissipating near Illinois Highway 71.
