PORTLAND, Ore. (KOIN) – You’re almost there! We’re getting closer with just one more day, and then it will feel colder with lowering snow levels.
Until then, here’s how today plays out. Shower intensity picks up this morning. Wind gusts from the southwest may reach 15-20 mph in the Portland metro. Showers come to an end briefly this evening. Daytime highs will top off in the mid 40’s.
Up to a foot of snow may fall above 4,000 feet as a Winter Storm Warning is in effect for the Cascades until 4 p.m. What will make driving the passes especially difficult will be the blowing snow and low visibility at times.
All signs are pointing to colder air trickling in beginning Friday. This may bring snow levels down to the coast range by Friday morning or by Friday night. Saturday, Christmas Day we expect a mass of sub zero Arctic air to advance southward over the Pacific Northwest. That cold air will sink to the valley floor and if we mix in some moisture it may turn to a snowy scene for the holiday. Traveling over the weekend may be snowy and slow. Make sure to keep up with our updates this week.
