Big changes are happening to the weather pattern and that is going to mean big snow for the Cascades over the next week. Further South the Sierra Nevada range will see lesser amounts but will still see much needed fresh snow on the slopes.
The first weaker system pushed through the West Coast as of Thursday morning dropping 3-12 inches of fresh snow from the Cascades down through the Sierra. After a brief break in the action on Thursday the next system is poised to blast into the Pacific Northwest Thursday night.
This second storm is much stronger and colder and will last several days in the Cascades. We could see several waves through next Tuesday bringing continued snowfall and snow levels below 3,000 ft. By next Tuesday there should be several feet of new snow on the mountains.
Further South along the Sierra in California the storm will lose some of its punch. It will still bring lots of cold air on Sunday into Monday with several inches of snow possible through Monday. Another wave may dive down the coast on Tuesday bringing a few more inches.
The second half of next week we may see another break in the storms, but not for long as storms are lined up off the coast ready to roll in the following week.
