San Juan Mountains Weather Report. Friday December 23, 2011…08:49
An upper ridge of high pressure building in the northwest is pushing the passing low pressure south into Arizona leaving cloudy skies, some fog and a few snow flurries on the north side of the San Juans this morning. Clearing skies and cold temperatures with valley inversions will dominate the next few days even with abundant sunshine.
Quiet weather will persist into the holidays with temperatures slowly warming as the Pacific ridge gains strength over the Great Basin. This pattern will continue through Sunday then a short wave trough moves into the northern portion of the forecast area flattening the high pressure ridge allowing northwest flow. Some moisture will be carried with it along with a series of short wave disturbances…Too early to tell, but looks like unsettled weather Tuesday through Thursday with a chance of snow for the northern and central mountains leaving the San Juans dry. This is looking almost a week into the future so it will probably change, stay tuned.
