Life threatening wind chills were observed December 22-23, 2022 across much of northeast Colorado. This was the result of bitter cold temperatures and gusty winds behind the passage of an intense arctic cold front. The brutally cold readings in some instances meant frostbite was possible in 5 minutes or less. Here are the minimum wind chills observed.
