Arctic Front Reaches Southern Colorado Tonight, Bringing Dangerous Cold and Snow Through Saturday

Overview

• Temperatures will drop rapidly tonight with highs on Friday likely reached near midnight and falling through the day under low clouds and upslope flow.
• Wind chills will turn subzero Friday into Friday night, including -10 to -20F on the eastern Plains, and a Cold Weather Advisory is in effect for frostbite risk.
• Light snow is expected in the Pikes Peak Region by mid-day Friday, with the main wave late Friday into Saturday morning and totals generally 1–4 inches.
• Winter Weather Advisories cover most high mountain zones from Friday morning to Sunday morning, with more than a foot likely in parts of the San Juans and difficult travel on I-70 and U.S. 40.
