The Indiana Department of Environmental Management has forecast an Air Quality Action Day throughout Indiana for today. (Thursday)

Ozone levels are expected to be in the Unhealthy for Sensitive Groups range throughout the state.

Today will bring warm, dry, and sunny conditions.

Highs are expected to reach at least the mid 80’s across the state.

This is consistent with recent conditions, and ozone measurements have been increasing during this period as we have remained in the same air mass for multiple days.

This is expected to result in measurements continuing to increase and in Unhealthy for Sensitive Groups range for Ozone.
