Weather Synopsis for Friday night through Sunday
Our region just can't seem to fully shake the last of the clouds and showers. While the overall trend is for drying and clearing, isolated showers will keep the chance of precipitation lingering in the forecast.
Friday night and Saturday, a low-pressure system off the coast will very slowly mosey its way southward. As it does so, it will take the bulk of the moisture with it. Look for a few spotty showers to hang around, particularly along the west slopes of the Cascades near and north of I90. With a few breaks in the sky, low clouds and fog could form in the mountain valleys and Passes overnight. A bit of daytime heating will help clouds to gather and break, but increasing high clouds from the SE should keep most locations from going "bluebird" on Saturday.
The script flips as we move from Saturday to Sunday. Clouds and moisture arriving from the E will push into the mountains. This should cause most locations near and east of the Crest to become cloudy, with more sunshine closer to the ocean. Similarly, light upslope snow showers should develop along the eastern margin of the Cascades. This could result in a few inches of snow at some trailheads, with drier and sunnier conditions further west.

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.

Directions above indicate the direction the wind blows from on the 16-point cardinal scale. These winds indicate "free" winds, or those winds in the atmosphere not influenced by terrain. Topographical effects may produce greater or lower wind speeds in certain locations as well as significant variations in direction.

Extended Weather Synopsis for Sunday night through Tuesday
Split flow over the region leaves us stuck in the middle. Most weather systems head north into Canada or south into California. Without a major driver to the weather, we continue to see passing bands of mid and high clouds and even the chance for a few snow showers. While we do cool over the forecast period, conditions don't appear cold. Freezing levels seem to bottom out around 3000ft or so for much of the region. Weather models are hinting at a slightly more active pattern, but the storms seem weak and tend to fall apart as they approach the PNW Tuesday afternoon/evening.
