It currently looks as though we might not see much relief from smoke until Monday or maybe Tuesday, the state Dept. of Ecology's smoke blogger Ranil Dhammapala just wrote (noon Sunday), helpfully posting a satellite image with annotations to explain where the fresh air is now.
"It will be Monday before much of western WA and the central and northeastern foothills of the Cascades see substantial relief. For far eastern WA, plan for little relief before Tuesday," Dhammapala wrote.
You can check DOE's Smoke Blog, which is woefully inadequate for this area because Ecology won't install air quality monitors here (note their map's huge hole in the middle of the state), at https://wasmoke.blogspot.com/2020/09/where-are-you-when-we-need-you-most-o.html.
The blog is helpful in understanding our current situation, and is a good resource to check whenever fire season is in full swing.
For data statewide, including the Grand Coulee Dam area, check https://www.purpleair.com/map?opt=1/mAQI/a10/cC0#11.45/47.9335/-119.0206. The local Rotary Club has installed four monitors here.
Those monitors report Air Quality Index numbers on the US EPA PM2.5 standard or any of several others you can choose.
The current smoke inundation is from a buildup over the Pacific Ocean of wildfire smoke from California and Oregon finally making it to land.
The buildup covered over 936,000 square miles at one point before sifting over Washington and creeping up the Columbia Basin.
Okanogan County Emergency Managment reported Sunday afternoon: "A change in the weather pattern may bring some relief to the area on Monday, but smoky conditions will continue to create reduced air quality into all of next week. Public Health officials are urging people to remain inside during periods of poor air quality, and to wear a mask when going outside or traveling. If you are in need of a KN95 mask, you can contact your local city halls for distribution."
The air quality is so poor that health authorities advise using a portable air cleaner with a HEPA (High Efficiency Particulate Air) filter or a DIY box fan filter.
