One more night of bitter cold temperatures and wind chills can be expected tonight through early Monday morning. Cold Weather Advisories are in effect for the San Luis Valley and much of the southeast plains tonight through 8 AM Monday. Dress in layers and cover all exposed skin as frost bite could occur in as little as 30 minutes. #cowx
