Puget Sound Forecast: Showers at times today, most numerous along or near the Cascade foothills. Some sunbreaks or periods of partial clearing. Highs in the low to mid 50's.

Coast Forecast: Mostly cloudy to cloudy with showers. Highs in the low 50's. South winds 15-35 mph in the morning, diminishing in the afternoon.

Mountain Forecast: A mix of rain and snow. Trace to 3" accumulations will be possible-in the higher passes in the afternoon. Expect snow levels near 5,000' in the morning, possibly dropping as low as 4,000' in the afternoon. Pass highs in the low to mid 40's. West-southwest winds 5-20 mph.

Eastern Washington Forecast: Showers and sunbreaks; a chance of afternoon thundershowers east of the Columbia basin near Spokane, Pullman and Walla Walla. Highs in the mid 50's to mid 60's.

Extended Outlook/Discussion:

A cold front early Thursday morning will means a change from widespread rain to more scattered showers, and possibly some mid-day sunbreaks. The shift to onshore winds (mostly southwesterly) will probably cause showers to be most prevalent and persistent along/near the Cascade foothills.

Showers are likely to linger Friday, despite weakly building high pressure. Such showers will be most likely during the afternoon hours. Only scattered showers are likely Saturday morning, but do expect increasing rain late Saturday afternoon or evening as a new warm front approaches. A disturbance in the upper atmosphere will likely cause showers to linger Sunday. Showers are likely to diminish Monday as high pressure builds, and the potential for showers Tuesday will be small. I believe temperatures will reach well into the 60's with partly sunny skies.
