DENVER (CBS4) – Another storm is taking aim at Colorado and promises to bring more snow to the mountains starting late Sunday night.

The storm is being transported into Colorado by fast moving northwest winds in the upper levels of the atmosphere. And since the wind is from the the northwest, it will create our well known “downslope” effect along the Front Range resulting in nothing but dry weather for the Denver, Boulder, and Fort Collins areas as well as everyone on the Eastern Plains.

That being said, it will be sunny and chilly on Monday in the metro areas will high temperatures struggling to come close to freezing. Similar weather is expected on Tuesday followed by gradual warming trend starting Wednesday.

A Winter Storm Warning has been issued for the mountains west of Vail Pass as well as the mountains north and northwest of Winter Park from late Sunday night through Monday evening. These areas not only have the potential to see more than a foot of snow, they will also experience wind gusts over 40 mph especially above timberline causing considerable blowing and drifting snow over passes like Rabbit Ears Pass and Vail Pass.

For the mountains of Summit County and the Winter Park area, a Winter Weather Advisory has been issued for the same time as the warning; late Sunday night through Monday evening. The difference for these areas will be accumulation which should be slightly less than the areas in the warning.
