Seattle weather: Drier conditions for Tuesday

A weak ridge of high pressure will bring a drier day for Tuesday. A spotty shower is possible for some, but overall conditions will be more dry than wet.

The Brief

    • The Puget Sound area will be mostly dry with some sunshine, and light showers may affect the south sound in the evening.
    • Wet weather systems will return mid-week, bringing widespread rain and gusty winds Wednesday night.
    • Heavier rain is expected Thursday night into Friday and again on Sunday, as snow levels rise and temperatures warm early next week.

SEATTLE - Most of the Puget Sound area will be mainly dry today with a few light showers impacting the south sound this evening.

A weak ridge of high pressure will bring some sunshine to Western Washington today. There is a chance of a few light showers in the south sound this afternoon and early evening, but even those areas will be more dry than wet.

Heavy rains return to Seattle

What's next:

As the ridge shifts east on Wednesday, it will open the door to more wet weather systems in the second half of the week. Wednesday morning, widespread rain will develop on the coast and try to push into the Puget Sound area in the afternoon. Expect on and off showers during this time with widespread rain holding off until after sunset. Winds will be gusty Wednesday night in the usual spots in the north Puget Sound, the coast, and the Admiralty Inlet.

The next rounds of heavier rain and breezy winds hit Thursday night into Friday, and then again on Sunday. 

Snowpack has improved over the past few weeks in the Washington Cascades. Cooler March temperatures and more precipitation have helped build snowpack, even though many areas are still below average.
