Weather Synopsis for Tuesday night through Monday
A frontal system approaches the region from the NW on Tuesday afternoon, spreading moderate precipitation into coastal Western Washington with light precipitation starting up in the Cascades. Rain, snow, and moderate to strong winds should ramp up across the region through the evening hours with a frontal passage expected across the Cascades between 10 PM and midnight. The front should shift SSW winds westerly, driving winds through the mountain gaps and accelerating flow east of the Cascade Crest. Expect the front to also bring strong cooling.
We're expecting 6-8" at Baker and 8-12" of snow at Stevens Pass above 3500 ft through 10 AM on Wednesday with a convergence zone likely to enhance snowfall around Stevens Pass in the early morning hours. Snoqualmie should pick up mostly rain Tuesday night, but 1-3" of snow early Wednesday morning as the convergence shifts southward. Skies should partially clear on Wednesday from late morning onwards with snow levels remaining well below pass level.
A warm front lifts across the region Wednesday night bringing significant warming to Mt. Hood and areas west of the Cascade Crest. Warming should be delayed east of the Cascade Crest, peaking on Thursday as the weakening cold front gradually slides eastward, bringing a band of weakening precipitation along with it. The moderate rain and snow should impact the Olympics much of the day, the Mt. Baker area in the afternoon.
