Weather Synopsis for Friday & Saturday

Moderate and weakening NW flow is keeping a few light snow showers going along the west slopes early Friday morning, mainly at Stevens and Snoqualmie. Freezing levels dropped sharply overnight behind a weak passing frontal system as the upper flow turned more northerly.

Showers should end later Friday morning as the onshore flow weakens. 

A strong upper ridge of high pressure remains offshore and will keep the Pacific Northwest cool with low freezing levels through Saturday and beyond.

The ridge nudges closer to the coast and builds a little further northward Saturday allowing for clearing skies Friday night and plenty of sunshine for Saturday.

High clouds increase Saturday afternoon and night as a weak disturbance approaches from the northwest.
