Weather Synopsis for Saturday night through Monday
The end of the weekend features cool, showery weather. A weak trough reaches the coastline Saturday evening and pushes through the Cascades in the early morning hours. Light to moderate snow showers continue into the evening hours before decreasing into the light range overnight and through Sunday. A convergence band could bring a brief period of moderate precipitation as it lifts northward Saturday evening from Snoqualmie, through Stevens, into the Mountain loop overnight. The remnants may bring some minor enhancement to the Mt Baker area on Sunday as light snow showers gradually decrease for the west slopes of the Cascades.
Snow levels fluctuate from morning lows around 2500 ft to afternoon highs around 3500 ft through the weekend. Expect storm totals in the 2-8" range for the west slopes of the Cascades, with around an inch or less in the immediate lee of the Cascade Crest. Moderate W ridgeline winds continue to target Mt Hood into early Sunday. Mostly light to occasionally moderate W ridgeline winds continue for the mountain gaps, passes, and Mt Hood.
Shower activity winds down for the west slopes of the Cascades Sunday evening as a broad offshore ridge edges into the region. Generally light winds shift SWerly and start to increase ahead of the next system.
That frontal system approaches from the northwest with increasing light rain and snow developing in the morning and increasing for Snoqualmie Pass northward plus the Olympics, potentially becoming moderate for the west slopes of the Olympics and Mt Baker areas. Snow levels should rise to 3000-4000 ft. Expect SSW ridgeline winds in the moderate range for the Mt Baker area which is more exposed to a barrier jet forming along the west slopes of the Cascades.
