Weather Synopsis for Saturday & Saturday
A weak and weakening frontal feature drops south through the area on Saturday morning. The associated scattered rain and snow showers should bring the west slopes of the central and north Cascades less than an inch in most areas above 2500 ft, with several inches of snow accumulation likely at Mt. Baker. The scattered rain/snow showers should wind down with the fizzling front by early afternoon providing a chance of some filtered sunshine or even sun breaks later this afternoon.
Saturday evening should be mostly dry with a strong system quickly spreading increasing light rain and snow throughout the region in the early morning hours on Sunday. A well-defined warm front and cold front combination arrive Sunday morning, bringing heavy snow to most areas of the Cascades with strong winds above 5000 ft in many areas. As the fronts approach, expect a brief period of easterly flow before winds shift westerly by mid-morning. At this time it appears that Snoqualmie Pass will likely stay all snow, but a mix with rain is possible in the early morning hours before colder air moves in behind the front. Further south in the Mt. Rainier and particularly the Mt. Hood area, a better-defined warm sector of the storm should bring a bump in snow level early Sunday morning.
Moderate to locally heavy post-frontal rain and snow should continue and will likely intensify over Washington State in the afternoon as the detached and vertically stacked upper low moves onshore.
Many areas of the Cascades west slopes and passes should see around a foot of snow by the end of the day Sunday.
