CHEYENNE — Dangerously cold weather hit Wyoming on Thursday, with Casper experiencing a record low and wind chill readings below minus 40 recorded in some areas.
Some of the coldest spots were in southeastern Wyoming. The National Weather Service says the wind chill near Pine Bluffs was minus 48 and minus 27 in Cheyenne early Thursday morning.
But it was also very cold in Casper, which set a new record low for the day when the temperature hit 20 below zero Thursday morning. The previous record was minus 16 set in 1971.
The wind chill at Casper/Natrona County International Airport bottomed out at minus 40 degrees. Wind chills in the city fell to minus 34 overnight Wednesday.
Frostbite can occur in as little as 10 minutes in such conditions, according to the National Weather Service.
Buffalo also set a new record low of 14 below, breaking the 2014 record of 9 below.
The frigid weather followed 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 on Wednesday.
The National Weather Service says temperatures are expected to climb back into the 30s in Casper and Cheyenne on Friday.
