There is a winter storm watch in effect until 4am for the Mount Baker area. Another foot of snow is expected by tomorrow night.
That being said, the snow level will remain between 3,000-3,500 feet through Monday morning so more snow for the rest of the Cascade Mountains and passes are expected, but should be around 6 inches of new snow tomorrow.
We have a cold front that will drive heavy rain and breezy winds through western Washington during the early morning hours Sunday. This will push into the mountains and hammer out some serious snowfall as mentioned. By Sunday late afternoon, most of the showers will taper off (just light showers by mid-morning) and things will calm down for the remainder of the weekend.

We have a warm front that will slide our way on Monday. This looks to bring scattered showers to the mountains mostly, but a few showers could find their way into the lowlands. The Olympic Shadow will help to protect us from most scattered showers on Tuesday as well, so not expecting a wash out next week in any way. For Thanksgiving, the latest weather models are showing less and less rain chances. I’m not going to remove rain chances just yet, but I don’t think there will be any big storms on that day either. A random Thanksgiving weather fact for our area: Only twice in the past 10 years has Seattle been dry on Thanksgiving Day. We are below normal in terms of rainfall for this month, and the long range forecast has us drier than average through the rest of the year. We shall see.
