Overview

A strong winter storm brought widespread rain and snow to much of Eastern Utah and Western Colorado between February 26 and 28, 2017. This complex storm system arrived over the region from two different areas. Moisture, associated with another "atmospheric river" got swept northeast across our region, bringing rain and snow to Southeast Utah and Southwest Colorado.

At the same time, a strong cold front was moving very slowly south across Northeast Utah and Northwest Colorado. The moisture streaming northeast rode over the top of the cold air, resulting in a band of heavy snowfall along and just south of the front. The cold front slowly sagged into the Interstate 70 Corridor early on February 28th, bringing moderate snowfall to the valleys with heavy snow for the central mountains. Grand Junction got in to the snow game as well with spotters reports ranging from 1 to 3 inches.

The cold front and snow continued pushing south in the Montrose area and eventually slid through Cortez, Durango and Pagosa Springs Tuesday night (Feb 28, 2017). The entire time the cold front was moving south, rain and snow was falling over the mountains and valleys of Southwest Colorado, where snowfall amounts exceeded 3 feet in a few mountain locations with up to 10 inches for the valleys.
