Weather Synopsis for Monday night through Wednesday
A weak front is pushing through the area this afternoon and re-invigorating shower activity across the region. As the front shifts to the east tonight, onshore flow will increase and we'll see a Puget Sound Convergence zone take aim at the central Cascades from near I-90 to Hwy2 along with moderate westerly ridgeline winds. Another area of heavier showers will occur near Mt Hood and the base of the upper level trough. The area of convergence will shift north on Tuesday morning, shifting the shower focus to the Mt Loop Hwy and the Mt Baker area. Showers will become more scattered in the afternoon, with cloudier skies and sunbreaks along the west slopes of the Cascades/Olympics and Mt Hood and sunnier conditions along the east slopes of the Cascades. Snowfall totals through mid-day Tuesday should average 2-6" with 4-10" more likely for Mt Hood and along the west slopes of the Cascades affected by the convergence zone.
The wet weather will keep chugging through the short term. A stronger Pacific frontal system will move in late Tuesday night. Warm frontal precipitation will spread inland early Wednesday morning and a cold front will pass through Wednesday afternoon. The front will deliver a modest shot of snow above 3000-4000', with higher totals likely for the volcanoes favored in southerly flow.

LT = less than; WE or Water equivalent is the liquid water equivalent of melted snow in hundredths of inches. As a rough approximation 1 inch of snow = about .10 inches WE, or 10 inches of snow = about 1 inch WE.

Extended Weather Synopsis for Wednesday night through Friday
Showers will become more scattered Wednesday night and Thursday, except they'll be a bit heavier and more persistent for the Olympics since they sit closer to the trailing upper low. We'll see a similar diurnal trend as earlier in the week with snow levels starting out near 3000' and rising to 4000-5000' in the Thursday afternoon.
On Friday, we'll see the upper low pull away and dive south along the Oregon/California coast. However, an upper level trough extending SW from Alberta will keep an unstable air mass over Washington state and lead to scattered afternoon mountain showers. Drier and milder conditions are likely over the weekend as a ridge of high pressure attempts to build over the area.
