SJ-Weather_withJR_small-square_web

 

Today will be warm & sunny, but changing with increasing cloudiness and dropping air temperatures that precede a weak low pressure trough/cold front that will turn into another active weather period tonight/early Saturday and into Sunday morning favoring the west and northern San Juan mountains.

There will be typical spring convective activity so some areas will see rain/sleet/snow while others receive nothing, but by Saturday night terrain above TL should receive snow, (1-3″) as well as the lower valleys down to 6,000′ as the passing cold front reaches our southern mountains.  Sunday the atmosphere will begin to dry and warm up with a building ridge of high pressure dominating the western U.S. then Wednesday a potential trough arrives on SW flow.
