Weather Synopsis for Saturday night through Monday
A closed low off the Oregon coast maintains continues to drift off the Oregon coast. To the north of the low, a broad E-W band of precipitation developed on Saturday and continued across northern Washington into the afternoon. It has stalled just south of the Canadian border. The associated precipitation should become mostly light and decrease for Mt Baker, the Mountain Loop, and Washington Pass areas in the evening. As the upper low begins to drift southeastward overnight, the deformation band tilts SW-NE and follows the low. This should quickly ramp down lingering precipitation for Washington Pass and Mt Baker overnight, with a period of light rain and snow shifting from the Mountain loop south to Mt Rainier by morning. Precipitation mostly ends in the central Washington Cascades early Sunday morning, with lingering more showery precipitation for the southern Washington Cascades and Mt Hood areas as flow aloft becomes more northerly.
A shortwave ridge moves over the area Sunday evening, followed by a series of disturbances and very subtle troughs. Expect increasing light rain showers Sunday night through Monday with diffluent flow not conducive to more than weakly organized fronts. Snow levels should be in the 3000-4000 ft range and light W winds increasing into the light to moderate range by Monday.

Extended Weather Synopsis for Monday night through Wednesday
The pattern continues with weak disturbances, however, a bit of ridging offshore turns the flow more WNWerly. The ridge shifts over the area Tuesday evening and SSW flow increases overnight ahead of the next system. A deeper low slowly moves into the PNW offshore waters on Wednesday, with a moderately strong frontal system bringing moderate winds and rain/snow. Temperatures should be near seasonal norms.
