Scattered showers have been ongoing across much of northern Illinois and southern Wisconsin Tuesday evening, with a few isolated thunderstorms from time to time. As low pressure moves further into Iowa, thunderstorm coverage will increase across northern Illinois through Midnight.
The overall severe threat remains low, but a few stronger storms could have wind gusts capable of 40-50 mph. Better dynamics in the atmosphere remain focused to the south Tuesday evening, where a couple severe thunderstorm warnings have already been issued for west-central Illinois. The storm threat will continue through roughly 2am Wednesday with a couple showers, possibly mixed in with some snow, by sunrise Wednesday.
