San Juan Mountains Weather Forecast ~ Monday, January 8, 2018 @ 09:50


Warm and sunny early today with increasing cloudiness this afternoon ahead of the next Pacific storm currently just off the California coast. The San Juans will see light snow flurries beginning tonight and Tuesday morning. By late Tuesday/early Wednesday a cold front joins the main system with deeper subtropical moisture arriving on southwest flow.

This storm is a closed low passing through Az. & N. M. that will spin it’s moisture into the San Juans favoring south and west aspects. If the majority of models that are almost in agreement are correct, elevations above 11,000 could see 7-14″ of snow. Lower elevations will see an rain/snow mix then as the cold front kicks in the lower mountain valleys will also see a few inches of snow.

As the low moves east later Wednesday the flow will transition from SW to NNW favoring the NW aspects of the San Juans.  This may be the storm we’ve all been waiting so patiently for …
