Air Quality Crisis: Schools and Businesses Forced to Close as Wisconsin's Worst Air Conditions Show Signs of Improvement

The air quality in Wisconsin has reached its worst levels since 1999, with hazy skies and high concentrations of particulate air pollution. The Wisconsin Department of Natural Resources confirmed that this is a historic air quality event, and the National Weather Service predicts that the air should begin to clear this afternoon and improve significantly by Friday morning. While air quality is already improving in Milwaukee, central Wisconsin still experiences very unhealthy conditions. The current situation is a result of a combination of factors, including wildfire smoke, high-pressure conditions, and wind patterns.
