The next week will feature continued snow for northern coastal areas, while California will stay dry until later next week.
Two storms will hit the Pacific Northwest around the weekend, with the first bringing snow on Friday and the second dumping another round of snow Saturday night through Monday morning. Each of these systems could bring about an inch of precipitation, which may translate into 8–12" + of snow.
The one downside to these weekend storms will be a relatively high snow level between 4,000-5,000 feet. This means that the upper elevations of many areas will be all snow, but the bases could be a mix of rain and snow or all rain. So stay on the upper half of the mountain to enjoy the powder.
A big change in the weather pattern will start on Thursday, March 20th. The storm track will shift south from British Columbia and Washington and will begin to target California. The details of the new storm track are still murky, but it is likely that snow will return to Tahoe around the 20th and 21st, while some of this precipitation will still impact Oregon and Washington. After the 20th, British Columbia may turn drier.
