Smoky skies continue into Thursday with an Air Quality Alert in effect through Thursday 5 p.m. East of the cascades will remain under the alert until further notice due to very poor quality and continuing wildfires.

Poor Air Quality

Smoky skies continue into Thursday with an Air Quality Alert in effect through Thursday 5pm. 

Air quality improving

Smoke will continue to make the air quality unhealthy for some communities today. However, as onshore flow gradually picks up Thursday evening, better air quality is forecast into the weekend.

Smoky Skies

Smoke will continue to be unhealthy, but it will be an improvement compared to Tuesday and Wednesday. 

What's next:

Thursday will continue to be hot with highs in the mid to upper 80s to low 90s for Western Washington. The Heat Advisory remains in effect for Western Washington. It will be even warmer for Central Washington with highs near 100 and very poor air quality. The coast will be a few degrees cooler thanks to increased onshore flow.

It'll be another hot afternoon around Western Washington on Thursday.

Seattle weather will be smoky and hot on Thursday.

Fire Weather Watch

A Fire Weather Watch will go into effect Friday morning through Saturday evening due to gusty and low relative conditions. As we see a change in the weather pattern, onshore flow will help the west side with smoke, but it will make for gusty conditions east of the mountains. Fire risk potential will increase and create increased fire danger.

A Fire Weather Watch has been posted for Central and Eastern Washington from Friday morning through Saturday night.

Very dry air and low relative humidity will increase the risk of wildfire spread, especially with gusty winds. (FOX 13 Seattle)

Looking Ahead:

Skies will continue to clear into the weekend and highs will slowly cool back to seasonal average. We will see more sunshine and warm conditions into next week.

Seattle weather will cool into the low 80s for the weekend and much of next week.

Seattle weather will trend even cooler by Wednesday, with highs falling into the upper 70s. (FOX 13 Seattle)
