Strong to severe thunderstorms were slated to move into northern Illinois starting Saturday night, bringing potential damaging winds and hail in some spots, according to the National Weather Service.
In a post on X, the social media platform previously known as Twitter, the NWS said a line of storms was expected to move in around 10 p.m. and exit the region by around 3 a.m. or so. Potentially severe storms were possible in the orange shaded area below, which includes Kane, DeKalb and McHenry counties, as well as portions of other counties.
While damaging winds of up to 60 miles per hour and large, localized hail are the main threats, brief tornadoes could not be ruled out. Flooding in low-lying areas is also possible.
Although the severe threat will likely diminish early on, showers aren’t expected to let up for several hours – until around 6 a.m. or so. The chance for storms will return once again on Sunday.
