- Western/West Central Indiana, including the cities of: Crawfordsville, Covington, Delphi, Fowler, Greencastle, Lafayette, Newport, Monticello, Spencer, Sullivan, Terre Haute and all other cities within the area.
Very high temperatures, sunny skies, relatively low humidity and calm winds should produce stagnant conditions, and USG values are expected for tomorrow.
