There are three large wildfires in the interior that may be contributing, but I'm not too sure why it's suddenly so bad for the week. Usually you'd see that the wind is blowing all the smoke south and west towards us, but I don't see anything like that on the map. Probably just the good ol' heat dome. ¯\_(ツ)_/¯

Windy doesn't have a graph but most other services with an air quality index either don't have a forecast or don't use the World Health Organizations guidelines, apparently relying on national guidelines (Canada doesn't seem to weigh pm2.5 as heavily in their forecasts). Check out Breezy Weather and compare with government forecasts to see what I'm talking about.
Try to reduce outdoor activities, and wear a K/N95 or P100 mask if you have to go outside and look into purchasing an active air filter for you home if you are able. So far, Tuesday night will be the worst, getting up to 156 by 11pm. Will update this post with the forecast. o7


*Will be better by Thursday night, ~8pm
