The cold front blasted through a lot faster than expected yesterday morning and there was a sharp cut-off to the precip behind it. Alpine Meadows picked up another 9 inches in the past 24 hours at the summit bringing the storm total to 35 inches. We even picked up a few inches at the base.
The season totals is now at 114 inches at the summit which is 25% of the seasonal average and it’s only December 3rd. The base on the upper half of the mountain is now 3-4 feet.
The next storm moves in as early as Tuesday afternoon with light rain & snow. The snow levels will start pretty high up above 8,000 ft. The heaviest precipitation looks to fall during the day on Wednesday but it’s not really that heavy and the snow levels should stay fairly high until coming down near 7,000 ft. Wednesday afternoon as the precipitation ends. We could see 3-6 inches above 8000 ft.
Then a ridge of high pressure builds in off the coast of CA out around 140w longitude. This is normally a pattern of storms coming down from the North just to our East with shots of cold air for the Sierra. There is plenty of cold air up to our North in Alaska. We could see the first shot of colder air Sunday and another the middle of next week. It will bee a cooler and drier pattern for at least 10 days after Wednesday’s storm.
The stormy weather will possibly pick up again around the 17th and beyond. The long-range models show above average precipitation for CA weeks 3 & 4. BA
