An Arctic cold front arrives in Colorado on Friday, bringing bitterly cold temperatures and snow to the state. Wind Chill Warnings have been posted through Tuesday morning by the National Weather Service for counties across Colorado, including the Palmer Divide, Denver area, and eastern plains. Periods of dangerous wind chill readings are expected mainly during the overnight periods tonight through Tuesday morning. The wind and low temps will lead to wind chills of 20 below to 35 below zero, with the most severe conditions east of Interstate 25. The coldest readings, approaching 35 below zero, are expected late Monday night into Tuesday morning across portions of the Plains. The cold wind chills could cause frostbite on exposed skin in as little as 10 minutes. The National Weather Service recommends avoiding outside activities if possible during this period. "When outside, make sure you wear several layers of appropriate clothing, a hat, and gloves. Take precautions now to provide shelter for outdoor animals," said the National Weather Service.
