CASPER, Wyo –The Mullen Fire burning in the Medicine Bow-Routt National Forest 40 miles southwest of Laramie has left the southeast Wyoming region under a widespread haze.

The National Weather Service in Cheyenne says poor air quality is likely to remain for the weekend, with a reprieve possible on Sunday as smoke diverting south of Cheyenne. Ash continues to fall on the town of Laramie, according to U.S. Forest officials.
