Seattle weather: Lowland rain to pickup Tuesday
While snow is falling in the mountains, lowland rain will pick up around western Washington. Tuesday will be a damp day with close to an inch of rain possible. Isolated thunderstorms on Wednesday could produce some heavy downpours at times.
SEATTLE - A strong Pacific storm is rolling through Western Washington this afternoon and tonight, bringing a mix of wind, rain, and some impressive late-season snow in the Cascades.
Big picture view:
The storm is in full swing heading into the evening commute and overnight hours. Expect breezy conditions with gusts in the 20–30 mph range across the lowlands. Rain will be steady at times, but the real headline is in the mountains.
Snow levels start around 3,500 feet, then drop quickly tonight to around 1,500–2,000 feet. That means all Cascade passes will see accumulating snow, with heavy bursts developing overnight. Winter storm warnings are in effect, and travel could become difficult at times.

The storm system lingers, keeping things cool, showery, and a bit unsettled. Mountain snow continues, though much lighter than overnight. In the lowlands, expect scattered showers with a slight chance of a thunderstorm, mainly near the coast.
