Air quality around Puget Sound expected to improve by Friday

Another round of wildfire smoke from California has arrived in western Washington, but the air quality won't be nearly as bad as before.

SEATTLE โ€” Wildfire smoke from California has drifted back into western Washington, but the air quality won't be nearly as bad around Puget Sound as it was in mid-September.

Hazy skies will be noticeable again Thursday, but most of the smoke will stay above 3,000 to 4,000 feet.

Air quality around the Puget Sound region is dipping into the into the โ€œmoderate" range. However, air quality is not expected to be like the stifling stretch of "unhealthy" air that blanketed the Pacific Northwest in mid-September. Seattle's air quality was considered among the worst in the world earlier this month.

Temperatures are forecasted into the 70s and low 80s this week, but a layer of smoke could keep the warmth down slightly.

Onshore winds will start bringing cleaner air into the Puget Sound region Friday and into the weekend for improving air quality.

The hazy sky caused the full moon to appear a shade of reddish-orange. 

Experts said the smoke we experienced earlier this month was "historic." Although it was not the longest we have had to endure poor air quality, it was the dirtiest air we've had to breathe as a state, experts said.
