Weather Synopsis for Saturday night through Thursday
A ridge of high pressure anchored over the Intermountain West will lead to a dry weekend. A weak and splitting frontal system offshore has spread some high clouds over the area today.
There is some nuance to the freezing level forecast with offshore easterly flow continuing to draw colder air and low clouds through the Cascade Passes while much milder air can be found at higher elevations and along the west slopes of the Cascades and Olympics.
The cold pool along the east slopes of the Cascades will slowly erode and moderate through Monday with freezing levels on the rise, but low clouds and cooler temperatures will persist along the lower slopes.
Light to moderate easterly flow through the Cascade Passes and at ridge-crest for places like Crystal Mountain will also persist into Monday despite the overall warming trend.
