Weather Synopsis for Thursday & Saturday
A cool high pressure is shifting SE on a NW flow, bring sunny weather with light winds to the region on Thursday. The ridge axis will be over Washington State Thursday afternoon and evening. Freezing levels will rise during the day to 2000 ft or so and drop to near sea level at night.
High clouds are expected to lower and thicken Thursday night ahead of a system dropping down the west coast of Canada. We expect the frontal snow band to be relatively short-lived producing modest snow totals (generally 3-6") as it passes through the end of the day Friday. Snow is expected to increase during the morning hours in the Olympics and North Cascades, spreading SE during the afternoon and evening through the rest of the region. The bulk of the snow should hold off in the Mt. Hood area until late in the day. Models predict convergence developing behind the front in the late afternoon. As a result, snowfall rates may be locally heavy in the I-90 corridor or just south of Mt. Baker. Winds are expected to be the highest impact with this storm and will peak Friday afternoon with the frontal passage in the moderate to strong range and will be strongest near Mt. Hood.
Snow levels will rise slightly as the front approaches but will remain below pass level and below seasonal norms.
