Weather Synopsis for Friday & Saturday
A vertically stacked upper low off our coast will drift northward today. Steadier light to occasionally moderate precipitation extends over much of the region Friday morning. This moisture generally arrives on a SSW flow. Precipitation should become more showery by the afternoon. Expect spillover onto the east slopes of the Cascades with some light low-level E flow through mid-morning. The volcanoes will receive the most moisture. Snow levels should gradually lower in the 3500-4500 ft range.
Rain and snow showers become scattered to isolated as the upper low morphs into a weak trough overnight. Snow levels lower to around 3000-3500 ft.
Scattered to isolated rain and snow showers continue but gradually decrease as the weak upper trough moves onshore on Saturday. Snow levels remain steady but expect a slight mid-day increase.
