Residents in the Chicago area should prepare for potential localized flooding, strong winds, and reduced visibility due to wildfire smoke. The severe weather could disrupt evening and overnight activities, with storms persisting past midnight in some areas. Air quality remains a concern, particularly for sensitive groups, as smoke lingers. On Wednesday, high waves and dangerous rip currents on Lake Michigan may pose risks to swimmers. The combination of weather hazards and air quality issues could impact outdoor plans and travel.
