San Juan Mountains Weather: After Spring, Some Snow?

26 Feb San Juan Mountains Weather: After Spring, Some Snow?

Mostly sunny skies today with increasing high clouds moving into western Colorado and another day of very warm temps for February. Thursday, westerly flow brings Pacific moisture/snow in the morning to our area and the beginning of a series of juicy storms lasting through the weekend.  Thursday’s low pressure trough could bring 6-10″ of snow into the high country above 11,000′.

There will be a lull in the action Friday, but by evening the second storm (which is a series of smaller storms) will be on us and could last through Monday.  There is plenty of moisture carried by this large trough so snow totals could be significant.  The 1st wave of energy will move across western Colorado Friday night through Saturday p.m. bringing up to a foot of snow for the San Juans on SW flow.

Model details for the later storms Sat. through Monday are less confident, so new model runs in the future hold the changing details…  Snow should end by Sunday with SW flow shifting to westerly flow (zonal) and continue into next week.  If optimism prevails, SW aspects above TL could see 20-30″ of snow on the high end.
