Weather Discussion

Satellite observations show cloud cover thickening west of the Continental Divide and our first signs of snow showers just crossing the Utah-Colorado border as of noon. Snowfall will spread into the San Juan Mountains around sundown, and then spread north and east overnight. Snowfall rates ramp up a little before midnight, favoring the the San Juan Mountains, Uncompahgre Plateau, Grand Mesa, Elk and West Elk Mountains. These areas could generally see up to 9 inches of snowfall overnight with periodic snowfall rates of an inch an hour or so. Other mountain areas pick up a trace to 4 inches. Nighttime lows drop into the teens at 11,000 ft. This is initially a warm storm, so snowfall will be on dense side, with the potential for some rain below about 7000 ft.

Flow shifts to the west on Wednesday as the trough axis of the approaching low-pressure system passes through Colorado. This will help fuel good orographic snowfall for the Central Mountains, Wolf Creek Pass and the Park Range, with as much as an additional 8 inches of accumulation. Other areas should pick up 1 to 4 inches by sundown.  Westerly winds strengthen and expect lot of blowing snow. Snowfall tapers of Wednesday night but the strong westerly winds continue. 

The short lull in the snowfall doesn't last long. Our next system arrives Thursday night into Friday, and this next one looks stronger.
