Weather Synopsis for Monday night through Wednesday
A ridge shifting across the region will be centered over the Pacific Northwest Monday night. The ridge is responsible for dry weather, with thin mid-level clouds passing over northern portions of the forecast region at times. Ridgeline winds shift from NW to W as the ridge begins to flatten.
The ridge shifts eastward on Tuesday, but increasing SW winds ahead of an incoming system will bring the mildest day of the week to the Pacific Northwest despite the subtle cooling aloft. Temperatures will be particularly warm east of the Cascades. Moderate ridgeline winds develop for the Olympics and Mt Baker as the day progresses.
Tuesday night, precipitation and cooling arrive as a sharp SSW-NNE-oriented front progresses through the Olympics in the evening and the Cascades overnight. Precipitation favors the mountain loop through Mt Baker, where we expect 0.5-0.75" of water equivalent through Wednesday with local convergence enhancement the Mountain Loop. Other areas generally pick up less than 0.3" of water equivalent. Temperatures drop rapidly as the precipitation arrives, so expect a transition from snow to rain and snow levels dropping to 2000-3000 ft by early Wednesday. Shower activity tapers by the afternoon as sun breaks become more frequent across the west slopes of the Cascades. Expect more widespread clearing east of the Cascades.
