Puget Sound Forecast: Decreasing showers in the morning with some sunbreaks possible or partial clearing; then increasing clouds by mid to late afternoon. Increasing rain is likely by late afternoon or early evening especially south of Tacoma, spreading northward into the Sound during the evening. Highs in the low to mid 50's.
Coast Forecast: Mostly cloudy to cloudy with rain at times, especially early morning and late afternoon and evening. Highs in the low 50's.
Mountain Forecast: A mix of rain and snow at Snoqualmie pass, with morning snow showers likely at Stevens and White passes (and higher passes too). Trace to 4" accumulations will be possible. Pass highs mid 30's to low 40's. West-southwest winds 5-15 mph.
Eastern Washington Forecast: A mix of snow/rain showers will be possible in the morning from Wenatchee east to Spokane and south to Pullman, changing to rain showers. Only rain showers are likely to the south and west of that area, including Ellensburg, Yakima and the Tri Cities. Highs in the 50's to near 60.
Moist, onshore flow will continue behind that front overnight...and that means continued showers overnight, probably most persistent central and south Puget Sound.
Satellite images spanning much of the central and eastern Pacific show a succession of weather disturbances moving generally to the east. A stronger system will approach Wednesday night into Thursday morning; that's likely to bring substantial rain to most areas. Weaker disturbances are likely Friday , then again later Saturday into Sunday morning.
