What happened

The episode as NWS BOU wrote it up.

Moderate to heavy snowfall impacted the Front Range mountains and foothills to close out the month. Above 8 thousand feet, storm totals generally ranged from 4 to 9 inches, with locally higher amounts. The big winner in the event was near Blue Valley near Idaho Springs, which picked up 16 inches of snowfall. Trail Ridge Road was shutdown as snow drifts from 1 to 3 feet covered portions of the scenic highway. In addition, Colorado Department of Transportation closed Loveland Pass due to safety concerns, and several brief closures occurred along Westbound I-70, from Floyd Hill to Silverthorne. Along the urban corridor and in the foothills below 8 thousand feet, much needed rainfall up to 1.5 inches was observed.
