Weather Synopsis for Wednesday & Tuesday
Another atmospheric river event is well underway as copious amounts of moisture with a sub-tropical tap rise up and over an upper level ridge positioned well offshore. The heaviest precipitation should favor the west slopes of the central and south Washington Cascades. Strong NW flow aloft will allow for precipitation to quickly taper the further on travels east of the crest. Snow levels are on the rise today, albeit slowly. Snow levels will rise to 4000-6000' today, with even higher snow levels for the Olympics and Mt. Hood. W-NW winds will be strongest from I-90 and south throughout the short term.
The wet, mild and windy story doesn't change much overnight or tomorrow. Another pulse of warm frontal moisture will arrive late tonight with even heavier precipitation expected tomorrow. Once snow levels peak today or tonight, they should stay fairly static through Thursday.
