Seattle weather: Drier, cooler weekend ahead

The atmospheric river that’s been soaking Western Washington is finally on its way out with drier weather on tap for the weekend.

A cold front swept through Western Washington today and behind it, we will find a cooler and drier air mass. Snow levels will drop to around 3,500 to 4,000 feet, and showers will gradually taper overnight. A convergence zone may briefly set up over Snohomish County, but that should fade as we get into the overnight hours.

By Saturday morning, expect a much chillier start with lows dipping into the mid-30s to lower 40s.

Saturday brings a bit of a breather. We will keep a small chance of showers in the forecast, but most areas will stay dry for the majority of the day.

Snow levels continue to fall, bottoming out near 2,000 feet, but with limited moisture, mountain snowfall will be minimal. High temperatures will feel noticeably cooler, topping out in the mid-40s to low-50s.

Mostly dry this weekend

What's next:

Saturday night, a weak system brushes the north coast, bringing the best chance for precipitation along the coastline. Inland areas will stay mostly quiet, with overnight lows in the 30s. Some of the colder spots could flirt with freezing.

By Sunday, another weak system slides by to the north, keeping a chance of light rain in the forecast. Temperatures remain on the cool side, hovering right around 50 degrees.

Looking ahead, we get a short dry break Sunday night into Monday as a weak upper-level ridge builds in. The next round of rain showers will arrive on Tuesday and Wednesday.
