San Juan Mountains Weather Forecast ~ Tuesday, December 13, 2016

Ed. note: Our friend Jerry Roberts has been watching the weather in the San Juan Mountains for decades. The services he checks out, in addition to his on-the-scene observations give us a unique view of the weather that affects us. With Jerry’s permission we are once again making his observations and forecasts available on TIO. Thanks, Jerry.


A short wave disturbance embedded in northwest flow will bring scattered orographic driven showers to the San Juans Tuesday night/Wednesday with a few inches (2-5″) for the north side of the range above 11,000′. By late Thursday a large closed low system moving eastward from the Pacific NW should bring a good storm to the San Juans on southwest flow.

Warm air early in the storm will keep snow levels in the upper mountain elevations then a cold front joins the action late Friday pulling the snow level down to valley locations… This storm has good potential for a big snow maker aided by strong winds especially for southwest facing terrain above TL. By Saturday SW flow switches to NW flow as the storm moves east then NNW terrain will be favored (RMP/Uncompahgre Gorge) and should see good precip. rates. The San Juans could receive more than two feet of snow from this storm by it’s conclusion Saturday evening. Will update as the storm develops.
