Chicago storms could bring damaging winds, heavy rain and hail on Tuesday, May 12, 2026, as forecasters warned of a stronger thunderstorm threat across the metro area.

Meteorologists said some storms may produce wind gusts up to 60 mph, creating the risk of downed branches, isolated power outages and difficult travel during the afternoon and evening commute.

What Areas Could Be Affected?

The severe weather risk covers parts of northeastern Illinois, including the broader Chicago area. Heavy downpours may reduce road visibility and cause ponding or localized flooding in low-lying areas.

Hail is also possible if stronger storm cells develop. Officials urged residents to monitor local alerts because storm timing and intensity may vary by location.

Travel and Safety Concerns

Drivers could face sudden rain, lightning and strong crosswinds on highways. Public transportation delays are also possible if storms intensify during peak commute hours.

Residents are advised to secure outdoor objects, charge phones and avoid flooded roads. Weather officials said people should seek shelter immediately if a severe thunderstorm warning is issued.

The storms arrive with summer-like warmth in the 70s, but cooler air is expected to return later in the week.
