CHEYENNE, Wyo. — Snowy weather returned to northern Wyoming on Friday, causing slick and hazardous travel conditions.

Winter storm warnings were issued for the Bighorn and Absaroka mountains while a winter weather advisory was posted for much of the northern half of the state.

The National Weather Service says the northern mountains could see up to 2 feet of snow while lower elevations could expect around 5 inches.

The Wyoming Department of Transportation said many area roads and highways, including Interstate 90 and I-25 north of Casper, were slick with snowfall.

Bitter cold air was accompanying the snowstorm with below zero wind chills expected across much of the state through Saturday night.
