Winter Storm in Southwestern San Juan Mountains, Colorado

Generally 10 to 20 inches of snow fell across the area with 14 inches reported at Dolores 16.8 ENE. Winds gusted in the 35 to 50 mph range with a peak wind gust of 48 mph at Lewis Creek.

With deep cold air in place following the strong Atmospheric River system and strong cold front, a third low pressure trough dropped down from the Pacific Northwest and passed through the Four Corners region. This brought moderate snowfall accumulations favoring the central and southern mountains of eastern Utah and western Colorado with much lighter amounts over the north. Since cold air was already in place, many lower valleys also received light to moderate snowfall accumulations particularly the central and southern valleys from along and south of the Interstate 70 corridor. Gusty winds led to blowing snow with some snow squalls across the southwest Colorado valleys at times due to the combination of snow, wind and visibilities less than a quarter mile.
