An Arctic front plunged temperatures Wednesday to around zero across much of Wyoming, with wind chills falling to minus 20 in some places.

The bitter cold was expected to worsen, with overnight lows of minus 6 forecast in Casper and minus 7 in Cheyenne, according to the National Weather Service. Wind chills as low as minus 30 were possible as gusty winds were predicted for the region.

Wind chills that low can cause frostbite within a half hour, according to the National Weather Service. The agency advised people to stay dry, dress in layers and wear mittens and a hat when going outside.

Due to such low wind chill temperatures, the Natrona County School District canceled all high school and middle-level practices on Casper Mountain, according to a district Facebook post.

Snow fell across parts of the state, with Casper expected to receive 1 to 3 inches by Wednesday night. Authorities warned the storm could make travel difficult, with blowing snow significantly reducing visibility. The snow was expected to taper off Wednesday evening, but cold temperatures were expected to linger through Friday morning, according to the National Weather Service.

The frigid weather comes after a stretch of unseasonably warm weather for central Wyoming. Temperatures climbed into the 50s in Casper earlier this week and were as high as 44 degrees a day before the cold front swept through the area.
