Weather Synopsis for Friday night through Tuesday
A frontal system currently passing through western Washington this afternoon will weaken and split as it passes inland. Before it weakens, it is delivering a generous shot of moisture for the Mt. Baker area and to a lesser extent the Paradise/Crystal/Chinook Pass region. Snow levels have been around 4500 ft in the north and 6000 ft over the south Washington Cascades. Cool east flow caused a wintry mix earlier this morning at Snoqualmie Pass before a switch to rain. Only a minor cooling trend is expected tonight behind the front.
Showers should quickly diminish overnight for all areas except for Mt. Baker, where more moderate rain and snow showers will linger for the first half of the night. The Pacific Northwest should be in a lull for much of Saturday with weather systems to our south and north, but not much happening in our region. The cloud forecast is tricky, but a partial clearing trend is expected for the west slopes of the Cascades and Mt. Hood in the afternoon, with a better bet for sunshine along the east slopes of the Cascades.
The lull between weather systems should continue through Sunday morning. The exception may be some light rain and snow that brushes the Mt. Hood area as it rotates up from a cut-off low pressure well to the south.
As a strong upper level ridge amplifies well offshore near 150W, a deep upper low will move south and dig off of our waters on Sunday. As the low sets up offshore, it will begin to rotate light snow showers towards the Olympics and west slopes of the Cascades during the day.

LT = less than; WE or Water equivalent is the liquid water equivalent of melted snow in hundredths of inches. As a rough approximation 1 inch of snow = about .10 inches WE, or 10 inches of snow = about 1 inch WE.

Extended Weather Synopsis for Tuesday night through Tuesday
The colder air bottled up over the interior of British Columbia should begin to seep into the region Sunday night, arriving through the Fraser River Gap and sliding along the east slopes of the Cascades as the coastal surface low pressure system slides further south off of Oregon. Details are hard to pin down, but light snow should accumulate along the north slopes of the Olympics, the east slopes of the Cascades north of I-90, and for the south Washington Cascades and Mt. Hood Sunday night through Monday. Much colder and drier air should mainly shut off the precipitation for the Mt. Baker area Sunday night but NE ridgecrest winds may increase during this period.
As the upper low shifts east and the ridge of high pressure shifts closer to our region, light snow showers should wind down Monday night, leaving us with a dry and cold day on Tuesday.
