Chicago weekend storms remain possible as humid air stays over the region, bringing mid-80s temperatures, lakefront cooling and a stronger rain chance before 90-degree heat returns later in the week.
The source forecast did not provide confirmed calendar dates, so weekday references are preserved without adding unverified dates.
Thunderstorms moved through the Chicago area overnight, but by about 7 AM Central time, most of the activity had shifted south and was leaving the region. Storm chances were expected to ease through the morning and afternoon, though isolated thunderstorms could still develop as temperatures climb.
Chicago Weekend Storms and Humid Conditions Continue
For the evening, forecast models showed only a stray thunderstorm risk, with most areas expected to stay dry overnight into Sunday morning.
On Sunday, easterly breezes are expected to continue through the day, keeping temperatures cooler near the Lake Michigan shoreline. Those lakefront winds should limit rain for much of the day, especially during the morning and late afternoon, before storm chances increase later.
Models showed storm activity beginning around 6 PM Central time, while highs again reach the mid-80s.
Monday Commute Rain Could Affect Chicago Area Travel
Rain chances become more meaningful after midnight, with isolated thunderstorms possible before showers expand in the following hours.
Rain is expected during the morning commute and could continue through noon and into the afternoon. That period appears to be one of the stronger chances for measurable rainfall in the Chicago area.
Highs are expected to remain in the mid-80s, keeping humidity in place as showers and storms move through.
90-Degree Heat May Return Later in the Week
The unsettled pattern is expected to continue into Tuesday, with showers and storms possible and highs gradually rising into the mid-to-upper 80s.
By Wednesday, temperatures are expected to reach around 90 degrees, with another chance of isolated storms. Ninety-degree temperatures are also expected Thursday and Friday. A thunderstorm chance remains on Thursday, while conditions are expected to clear Friday as a cooldown begins.
The forecast matters for Chicago residents because it could affect weekend plans, lakefront activity, the early-week commute and heat planning later in the week.
