SAN JUAN MOUNTAINS WEATHER FORECAST: SOME SNOW LIKELY, 3/3/13

03 Mar SAN JUAN MOUNTAINS WEATHER FORECAST: SOME SNOW LIKELY, 3/3/13

There are currently partly cloudy skies with increasing cloudiness throughout the day.  Western Colorado will see the southern portion of a split trough arriving on WNW flow bringing some snow into the western San Juans later today and by mid-afternoon the flow will spread moisture into the 4-corners.  Should see a rain/snow mix in the lower valleys and blowing snow in the mountain passes.

An associated cold front will enhance snow fall tonight/tomorrow in the higher elevations as instability increases.  Drier air arrives from the NW behind the front on Monday but remaining moisture will perpetuate snow flurries through midday.  Higher WNW aspects above 11,000′ could see 8-12″ of snow from this fast moving storm.

A ridge of high pressure from the Great Basin builds Monday evening and by late in the week a closed-low digging south into southern California will travel east into Az. and New Mexico bringing our next storm Friday afternoon into Saturday.  It’s too far into the future to be over confident because the various models DEFINITELY are not in agreement on location and movement of the closed-low.
