The Indiana Department of Environmental Management (IDEM) has extended the forecast of an Air Quality Action Day (AQAD) through Friday.

Ozone levels are expected to be in the Unhealthy for Sensitive Groups range (Orange) in the following areas:

• Southeast Indiana, including the cities of: Brownstown, Corydon, Jeffersonville, Madison, New Albany, Salem, Versailles and all other cities within the area.

• Central/East Central Indiana, including the cities of: Bloomington, Brookville, Columbus, Frankfort, Indianapolis, Greensburg, Kokomo, Lebanon, Martinsville, Muncie, Richmond and all other cities within the area.

Continued unseasonably warm temperatures combined with low humidity, sunny skies and light wildfire smoke are expected to contribute to elevated ozone levels that are forecast to reach the Unhealthy for Sensitive Groups (USG) range.
