The episode as NWS GJT wrote it up.
Following another brief lull, a stronger wave carried a more substantial plume of Atmospheric River moisture in the 95th percentile northward allowing for heavy mountain snowfall of well over a foot to favor the Elkhead and Park Mountains in northwest Colorado. Some central Colorado mountains also saw light to moderate amounts with little snowfall across the southern mountains. Milder air continued to limit snowfall to the higher elevations.
