Weather Synopsis for Friday & Monday

The longwave trough associated with the seemingly never-ending stream of moisture that has affected our area over the last 36 hours will sweep through later this morning. Showers may take a bit of break mid-day but a trailing disturbance should reinvigorate shower activity for the Olympics and west slopes of the Washington Cascades later this afternoon. The Mt. Baker area will continue to experience locally heavier precipitation compared to the rest of the region. Snow levels will be slow to lower from 4500-5000' this morning to 4000-4500' this afternoon as cooler air trickles into the region. 

Weak upper level ridging will pass over the area tonight as we take a brief pause from widespread precipitation and winds. A quick-moving frontal band will approach the coast on Saturday morning and pass through the Cascades late morning/mid-day. While this front is moving too quickly to bring copious amounts of moisture, there does seem to be a brief but intense 3 hr period of precipitation focused north of the I-90 corridor along the west slopes of the Cascades. Snow levels are a bit tricky as well with a short period of easterly flow dragging snow levels down to Pass level for the Snoqualmie, Stevens and White Passes in the morning before rising in the afternoon. Snow levels should once again settle in the 4000-5000' range Saturday afternoon with light post-frontal shower activity.
