A major storm system moved across the region during the day on December 15th, providing widespread impacts to southern Colorado. Across southern Colorado, extreme winds, high to extreme fire danger, dust storms, heavy mountain snow, and snow squalls were all observed.

Environment

A potent upper level system and surface low approached the region late in the day on the 14th, and then lifted across Colorado during the day on the 15th as a strong upper level jet of 120 KT translated overhead.
This setup favored heavy mountain snow across the Continental Divide, primarily the eastern San Juan mountain. Meanwhile, lighter amounts of snow were observed across the central and eastern mountains. As this system pivoted across the region, the strength of this system and some weak instability supported the development of snow squalls from the Continental Divide east into parts of the I-25 corridor.
The strong jet moving across the region as well as mountain wave action produce widespread extreme winds over much of southern Colorado. The really dry conditions in place and these extreme winds then produced widespread blowing dust over much of the plains.
High/Extreme fire danger was also noted given the strength of the wind field and falling RH values, falling well into the teens
