...AIR QUALITY ALERT IN EFFECT UNTIL MIDNIGHT TONIGHT...

The Illinois Environmental Protection Agency is forecasting Unhealthy for Sensitive Groups (USG) for ozone for all of Illinois today.
Warm, dry, and sunny weather along with intensifying drought conditions are major contributing factors for ozone formation. Air Quality Index (AQI) forecasts and levels can normally be found at AirNow.gov, but the unique widespread nature of this episode prompted this extra National Weather Service alert.
Active children and adults, especially people with pulmonary or respiratory disease such as asthma, should limit prolonged outdoor activity.
