Seattle weather: Stormy stretch, then a ‘spring break’ from the rain

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.

Temperatures will stay cool, around 50 degrees.

Dry weather to end the week

What's next:

High pressure begins to build in, bringing drier weather and some sunshine. It will be chilly in the morning with lows dipping into the 30s. Areas of frost are possible, especially around the South Sound. Afternoon highs will rebound into the 50s.

Friday and Saturday will bring more dry weather with warming temperatures. Another system approaches over the weekend, bringing showers back to the area on Sunday.
