11 Jan San Juan Mountains Weather Report, 1/10/2015

Clouds are beginning to move into the 4-corners this morning ahead of the next San Juan storm. By later tonight/Sunday morning scattered snow showers will increase as an upper level trough moves into the mountains. With a lack of strong storm dynamics don’t expect more than 3-6″ and maybe a little more for the higher terrain… rain/snow mix in the lower valleys.

This short lived disturbance will slowly come to an end by Sunday evening and replaced Monday by WSW flow from a stronger wave moving into the Great Basin. Two of the three models I look at share a positive world view of widespread snow for western Colorado Monday afternoon through Tuesday afternoon. Colder temperatures come with this storm so the valleys will see some snow but it’s too early to anticipate amounts because future models are surely to change as time goes by. Could see 2-4″ for the southern valleys and possible 6-10″ for the alpine regions especially on WSW aspects.

As the system exits Colorado west coast high pressure ridging with dry conditions will move back into the Rockies for the remainder of the week.
