The episode as NWS GJT wrote it up.
A cold front progressed across western Colorado and generally produced light snow across the region. However, instability associated with the front led to the development of a strong convective snow band which extended from the La Sal Mountains in southeast Utah to the West Elk Mountains in west-central Colorado. This band produced localized snowfall totals of up to a foot across portions of the West Elks.
