Weather Synopsis for Saturday night through Monday

The Pacific Northwest is in a weather pattern, with frontal systems arriving every 24-30 hours. The first and weakest in the series passes through the Cascades on Saturday early afternoon. Light to moderate rain and snow showers continue through the evening with a cooling trend.

System number two doesn't hesitate for a break in the action. Steadier rain and snow develop with an approaching warm front overnight. The moderate to heavier precipitation targets the Olympics and the volcanoes, with lighter precipitation for the passes and east slopes of the Cascades. Precipitation and moderate to strong ridgeline winds peak Sunday morning with the cold frontal passage. Precipitation becomes light to moderate and more showery during the afternoon as winds shift from SSW to SW. Snow levels start the day in the 2500-3000 ft range, rising to 3000-3500 ft with a chance that Snoqualmie Pass proper shifts from snow to rain in the afternoon.

Light to moderate snow showers continue on a cooling trend Sunday night as winds decrease. Light showers transition to stratiform rain and snow on Monday afternoon, increasing along with ridgeline winds as a front approaches.
