The snow has been falling almost nonstop over the past week across the Cascades and the Sierra. As of Wednesday morning, some ski resorts in the Tahoe Basin were reporting up to eight feet of fresh snow. That has buried the ski resorts in much needed snow to get fully open for the holidays.
The pattern over the Pacific is changing and much quieter weather is in store over the next week. The pattern is going to be shifting East with the trough that has been sitting over the West moving over the East, and the ridge that has been out near Hawaii shifting off the West Coast.
There will be a low pressure system cut-off from the jet stream that will spiral down the West Coast over the weekend. That should reinforce the cold air and bring light snow for the mountains. However, I do not expect more than a few inches Friday and Saturday.
Next week the forecast models are struggling with the pattern as it shifts to a drier one. Some of the forecast models bring a weakening storm into the West Coast Wednesday and Thursday with several inches of snow, while others keep any storms deflected to the North. We are expecting the temperatures to stay cold though—keeping the freshly fallen snow in great condition over the next week.
