The weekend should start out springlike Saturday, but a change colder and moister for the mountains is likely Sunday. The Front Range may not see the cooler weather until late Sunday.
Front Range foothills and eastern plains
Saturday should be another mild day, but high level moisture ahead of a Pacific storm may cause more cirrus clouds than we see today. The mild weather should continue into Sunday until the axis of the Pacific storm moves through late Sunday or Sunday night. Other than a chance for brief showery snow and rain, it should be mostly or entirely dry for the foothills and eastern plains. The most noticeable change may be the tendency for strong gusty northwest winds ushering in the cooler weather by Sunday evening.
Mountains and West Slope
After a mild Saturday the Pacific storm that is bringing much-needed rain and snow to California will begin to move into western Colorado Sunday. It will loose some moisture along the way, but there will likely still be enough to cause enough snow for wintry conditions on the high passes Sunday and Sunday night. Around 6 inches is probable in the high mountains and west-facing slopes.
