Weather Synopsis for Friday night through Sunday
A few popcorn showers near and west of the Cascade crest will peter out tonight as an upper level ridge builds over the area. NW flow on the leading edge of the ridge will translate into moderate to locally strong NW winds at ridgeline and alpine areas Friday night through Saturday. The ridge will quickly break down on Saturday. We’ll start the day with mostly sunny skies for southern areas and partly to mostly cloudy skies closer to the Canadian border. In the afternoon, cloud cover should increase for all areas with potentially a few flurries or raindrops over the Olympics and northwest Cascades before sunset. After a cool start to the day, a low pressure system curling north towards Vancouver Island will push milder air into the region by Saturday afternoon, with freezing levels rising to 4000-6000’.
The frontal system will pass through the area Sunday morning with a burst of moderate precipitation. The mild snow levels experienced Saturday night will come down a bit at the onset of precipitation but some lower elevation trailheads and Passes may see rain at the beginning of the storm. As the front passes through late morning or mid-day, snow levels will settle into the 4000-4500' across the area. Up to 0.50" of water equivalent may fall from the Mountain Loop Highway and northwards including the Mt Baker area. Showers will continue Sunday night, with those same areas favored to pick up similar precipitation amounts. A ridge will temporarily build over the area on Monday with dry conditions expected.

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 Sunday night through Tuesday
Forecast models are in poor agreement on how the pattern evolves next week. It's unclear how a broad trough carved over the Canadian Prairies/northern US Plains merges with a storm track under-cutting a strong ridge of high pressure over the northeastern Pacific. For now, run-of-mill storms with temperatures near or slightly above normal seem like a fair bet.
