Chicago's Air Quality Plummets to World's Worst Due to Canada Wildfire Smoke

Chicago woke up to the worst air quality in the world due to smoke from wildfires in Canada, which has spread across parts of the Great Lakes Region surrounding Chicago, including most of Wisconsin and parts of Michigan, Illinois, Indiana, and Ohio. The air quality is deemed unhealthy or unhealthy for sensitive groups in major cities in the Midwest, including Chicago, Milwaukee, Indianapolis, Cincinnati, Detroit, and Minneapolis. The smoky air and haze is expected to linger in the region Tuesday and overnight, but should be slowly pushed south and west throughout Tuesday, and gradually diminish in coverage on Wednesday.
