Comfortable weather is likely to stick around a couple of more days, until an onshore flow from the Pacific arrives Sunday.
Saturday should reach 78 degrees, followed by highs in the upper 60s to low 70s next week, said National Weather Service meteorologist Dustin Guy. Drizzle or brief showers are possible Monday or Tuesday.
Smoke from Alberta wildfires will leave the state as moist air enters the Puget Sound region over the weekend.
“It’s already starting to thin out now,” Guy said Friday morning. Smoke particles stayed high enough all week to prevent health dangers in Western Washington, where air quality was listed by Puget Sound Clean Air Agency as good Friday afternoon. But in the central and east regions of the state, readings in Spokane, the Tri-Cities and Walla Walla hovered above 100, or unhealthy for sensitive groups, according to Purple Air’s online map.
Smoke should stay away from Seattle for a while, though it could possibly return late next week, Guy said.
Friday morning’s opaque horizons weren’t from smoke but a normal springtime marine layer of evaporated seawater.
It will feel cooler this weekend, Guy said, but that’s only compared to last weekend’s unseasonable heat in the upper 80s.
Looking ahead to Memorial Day, the six- to 10-day forecast for the Seattle area calls for above-average temperatures and below-average rainfall, Guy said.
