A stagnant air mass continues across the region today, combined with unseasonably warm temperatures, low humidity, sunny skies, and light wildfire smoke may drive ozone levels once again into the Unhealthy for Sensitive Groups (USG) range across these regions.

Southeast Indiana, including the cities of: Brownstown, Corydon, Jeffersonville, Madison, New Albany, Salem, Versailles and all other cities within the area.
A stagnant airmass will persist across the region through Saturday, and the combination of unseasonably warm temperatures, low humidity, sunny skies, and light wildfire smoke could once again elevate ozone levels into the Unhealthy for Sensitive Groups (USG) range.
