An unseasonal weather pattern is in place for the start of this week.
Dry conditions are in place, rain deficits also exist and temperatures are running slightly above the averages for middle December. The weather conditions should remain fairly quiet for the first half of this week. There will be some cloud coverage building in and wind speeds should remain light until we move past The midweek period.
A very unsettled weather pattern is continuing to develop for the upcoming weekend and beyond. A large area of low pressure and subsequently several more that will follow (keeping things unsettled through the weekend and into early next week) will be moving eastward from the PACNW after Wednesday December 22, 2021. This is going to be a series of moderate to high moisture content storm systems that will move through Colorado (first for the end of this week, second for the weekend and third for the start of next week). There will also be mild temperatures during the day to support rain in the lower elevations with rain to snow during the early morning hours and all snow in the mountains. All mountains will do very well with these storms and Winter Weather Advisories and Storm Warnings are expected in the higher elevations. The temperatures will be quite mild through this weekend and snow levels should only drop to 6-thousand feet. That puts Montrose right at the rain/snow line, good for accumulating snow on the grassy areas. Grand Junction will be below that snow level and as such should be dealing with rain showers keeping streets wet along with a rain/snow mix during the colder hours from midnight until noon. This puts a chance of experiencing snow December 24th and 25th in the forecast for the lower valleys and a very likely/higher chance in the mountain zones. There will be more snow and these unsettled conditions are anticipated through the start of next week.
