Winter Weather in Flattop Mountains, Colorado

Generally 4 to 8 inches of snow fell across the area with locally higher amounts up to 16 inches at Bison Lake. Wind gusts stayed below 45 mph with a peak wind gust of 43 mph at Dead Horse RAWS.

A deep closed low pressure system moved through the Great Basin into the Four Corners region on the heels of another system. This low brought deep Atmospheric River moisture from the Desert Southwest through the Four Corners ahead of it, along with impressive dynamics and a strong jet to produce moderate to heavy snowfall across most mountain ranges of eastern Utah and western Colorado where the highest amounts of 1 to 2 feet of snow fell across the mountains of eastern Utah and southwest Colorado. Temperatures remained mild enough that most lower valleys saw primarily rain, limiting snowfall accumulations. Winds were quite strong as well with gusts in the mountains in the 60 to 80 mph range on average, leading to impacts from blowing snow.
