Weather Synopsis for Friday night through Sunday
The Pacific Northwest transitions back to more typical early spring weather as we head into the weekend. A cold front ahead of a closed low ultimately ushers in the cooling, but also extends a band of moderate rain and snow, lifting northward largely ahead of the cooling. Peak precipitation occurs during the evening hours for Mt Hood, overnight for the southern and central Washington Cascades, and the front stalls over the northern Cascades on Saturday. Models differ regarding whether some moderate precipitation lingers over the central Washington Cascades into the morning hours. Snow levels start around 5500-6000 ft Friday evening, but drop to 4000 ft on Saturday. Upper elevations across the region can expect 4-8” of snowfall, with those amounts extending into middle elevations from Stevens Pass northward as snow levels lower to 4000 ft by Saturday. Expect a relative break in the action for areas south of the precipitation band before more scattered light rain and snow showers develop from Snoqualmie Pass south to Mt Hood during the afternoon.
Light rain and snow showers continue across the region on Saturday night under the influence of a broad trough. NNW flow aloft develops on Sunday, with scattered to isolated convective showers for both sides the Cascades from around Stevens Pass southward. Snow levels range from 3000-4000 ft. Expect breaks in the clouds with more plentiful sunshine east of the Cascade Crest, particularly during the morning hours.
