06 Jan SAN JUAN MOUNTAIN WEATHER: SOME SNOW?
Friday is a transition day of cooling temperatures and high clouds moving into the area. The first snowfall in a long while is due to arrive Saturday evening in the San Juan Mountains. The ridge of high pressure that has been parked in our backyard forever is beginning to flatten and is pushing southwest as the polar jet begins to dip south out of Canada with it’s nose eventually wrapping around the 4-corners while a cold front moves south of I-70.
The heaviest snow will move along the frontal boundary late Saturday early Sunday morning with potentially 2-4″ for favored WSW slopes above 11,000 feet. By midday Sunday we’ll be out of snow clearing from NW to SE with trough passage. Dynamics aren’t great for this storm depositing much snow for the San Juans.
Monday a high pressure ridge builds back into the area with warming temps and sunny skies. Tuesday a Pacific short wave passes with a slight chance of light snow then more high pressure into next weekend..
