Weather Synopsis for Thursday night through Saturday
Cloud cover and light snow increase Thursday evening as a disturbance approaches the region on NNW flow. Light snowfall peaks in many areas overnight and tapers rapidly from north to south on Friday morning. High-resolution weather models continue to suggest the highest accumulations will be along the farthest west slopes of the Cascades for areas like Paradise, Timberline, and in convergence bands over the central Washington Cascades. Favored areas could pick up 2-6" of snow, but most areas, including the east slopes of the Cascades, will see less than 2". Snow levels remain around 2000-2500 ft through Friday. Models focus the moderate W and WNW ridgeline winds along the I-90 corridor and at Mt Hood overnight. In the latter case, these winds could linger into the morning hours.
A shortwave ridge moves into the region Friday afternoon, bringing mostly cloudy skies, decreasing light winds NW winds, and a diurnal bump in freezing levels. Skies partially clear Friday night as the ridge axis moves toward the coastline. On Saturday, the ridge flattens slightly, but moisture remains north of our region. Expect partly cloudy skies with moderating temperatures as freezing levels rise to 3000-5000 ft by the afternoon.
