CHEYENNE, Wyo. (AP) — Wyoming residents woke up Friday to some of the coldest temperatures and wind chills in a long time.

Temperatures across the state Friday morning were well below zero, with many readings in the 30 below range.

The National Weather Service says the temperature in Laramie dipped to 40 degrees below zero overnight. That's the fifth coldest reading in Laramie in more than 50 years. The top four coldest temperatures in Laramie occurred in 1962 and 1963.

Wind added to the chill in the air, making it feel like 60 below in some areas and prompting warnings about frostbite and hypothermia.

However, the worst of the cold should be over as temperatures and expected to warm up through the weekend. Some areas of southeast Wyoming could see 40s on Sunday.
