Weather Synopsis for Tuesday & Wednesday
Showers in brisk westerly flow will continue this morning with locally heavier showers near Mt Hood and near areas of convergence along the west slopes of the Cascades from I-90 and north through Whatcom County. The convergence zone(s) will drift north and weaken through mid-day. This morning's heaviest accumulations will fall over the western sections of the Cascades in Whatcom/Skagit and Snohomish Counties as well as Mt Hood, where an additional 3-6" of snow may fall. We'll see lighter accumulations elsewhere.
Showers will become scattered and lighter this afternoon. Low clouds will stick along the Olympics, Mt Hood area, and the west slopes of the Cascades and Passes but there will be sunbreaks. You won't have to travel too far east of the Cascade crest to find much sunnier skies Tuesday afternoon along with slightly higher freezing levels.
We'll have a brief reprieve tonight as upper level ridging passes inland. A stronger frontal system will start to spread warm frontal precipitation inland during the morning hours. Cool easterly flow will help nudge snow levels down to 2500' across much of the Washington Cascades at the onset of precipitation Wednesday morning. Snow levels will inch up during the day, and pop around 4000-4500' in the late afternoon as a weakening cold front pushes through. Precipitation amounts look to be in the 0.25-0.75" range during the day, with the highest totals likely for Mt Hood, Crystal/Paradise and the Mt Baker area. Mt Hood will be the windiest and mildest location during this storm.
