Clearing skies will lead to some frigid overnight temperatures. By Sunday morning, we'll see negative lows and single digit temperatures across Southern Colorado. Wind chill values during the overnight hours will be as cold as -10 to -25 degrees, and the worst of it will be across the eastern Plains and the San Luis Valley. These areas will be under Wind Chill Advisories and Wind Chill Warnings through 10 am Sunday. If you have to be outside during this time, make sure to cover all exposed skin to avoid the potential threat of frostbite. This can develop within 15-30 minutes with wind chill values this low.

High pressure, our fair weather maker, will deliver a much welcomed warming trend for the first part of the work week. By Tuesday, a digging trough of low pressure will spread stronger gusts into Southern Colorado, with possible high fire danger. Our forecast will remain windy through Wednesday before a cold front brings some moisture and the potential for light snow showers Wednesday night into Thursday morning. Accumulations look light this far out. Following the cold front will come another dose of cold weather on Thursday.
