Weather Synopsis for Sunday night through Tuesday
545pm Update: Slightly increased precipitation overnight for West Central, Paradise (West South) and Snoqualmie Pass. Also increased the wind speeds forecast for Mt Hood tonight.
Post-frontal showers and moderate to strong SW-W winds will continue through this afternoon and overnight with the heaviest showers along the west slopes of the Cascades and Passes. We'll probably see a brief lull in intensity later this afternoon before showers increase again overnight as the trailing low pressure center moves inland. The first half of Sunday night, the focus for the heaviest showers will continue to be along the west slopes of the Cascades from Hwy2 and northward but that should shift to I-90 to down towards Mt St Helens on Monday morning. Snow levels will gradually lower as colder air filters into the region. Showers will become more scattered and light during the afternoon. with decreasing cloud cover (and increasing sunshine) for the north Cascades and generally areas further east of the Cascade crest. Strong westerly winds will stick around the longest in the Mt Hood area.
A broad trough will extend over the area Monday night through Tuesday with dry conditions expected. Daytime convective clouds and a few isolated showers may pop up Tuesday afternoon but otherwise expect a break in the weather pattern.

Extended Weather Synopsis for Tuesday night through Thursday
It sounds like a broken record but there's still a fair bit of uncertainty regarding how the midweek weather pattern evolves. A strong but skinny ridge over the NE Pacific will be undercut by the storm track in westerly flow heading into CA/OR. Some moisture may work its way north on Wednesday and Thursday with light and insignificant snow amounts near the Canadian border trending towards a more moderate shot of precipitation down near Mt Hood. Some models also have a mini-Fraser River Valley outflow event over this midweek period. It does look like snow levels will drop but there's low confidence how long or how cold the pattern will turn.
