There is actually a chance for measurable precipitation late today or this evening along the Front Range urban corridor. It will likely be showery in nature, so some areas may get missed. The best chances are north of Denver, and there may be some pockets of briefly heavier showers with thunder. For the lower elevations it is likely to be mainly rain, but there could be some small hail or snow in some of the heavier pockets. Cheyenne has a better chance for some measurable snow. And snow is likely in the mountains.
This storm will pass quickly and mild weather is likely through much of the weekend. But a similar type of storm (except maybe a few degrees colder) may move into the area late Sunday.

Since the weather won’t be too exciting, the change to Daylight Saving Time might be the most noticeable thing this weekend, and quite easy to forecast.
But there is some change in the weather on the way. A Pacific cold front will sweep through the state late tonight and Saturday bringing localized areas of snow to some of the high passes and mountains, mainly north of I-70. For the Front Range foothills and plains there is very little chance for precipitation with the front, but there may be a period of gusty northwest winds. Afternoon temperatures are likely to be about 10-15 degrees cooler than today, which still isn’t too bad. The dry weather should continue into Sunday. A storm passing south of the state on Sunday may bring some high elevation snow to the San Juans and Sangre de Cristos, but nothing major.

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.
