Overview
- Parts of the Chicago area, especially near and north of I-80, sit under an Enhanced (level 3 of 5) severe risk for Tuesday, with the greatest threat expected Tuesday evening into the night.
- Storms in the region could produce large hail, damaging winds and a few tornadoes, and meteorologists urge residents to keep overnight alerts on because some of the strongest cells may arrive after dark.
- Southern and southeast Wisconsin also face an Enhanced risk Tuesday, with repeated rounds of rain likely to drop 1 to 3 inches in spots and raise a localized flooding threat on already wet ground.
- A strong warm surge keeps highs in the 70s and 80s through Friday across the Midwest and into the Northeast, with a daytime “cap” likely holding off many storms until late day when instability peaks.
- Wednesday retains severe potential depending on how Tuesday night storms evolve, followed by a brief lull late week before a front brings cooler weekend temperatures.
