A plume of moisture associated with an Atmospheric River surged across western Colorado with precipitable water values increasing up to 400% of normal. A Pacific system moved across the region which, when combined with the well above normal moisture, resulted in moderate to heavy snowfall across the mountains of western Colorado.
