Above is the forecast for the distribution of smoke from wildfires at 6 p.m. PST November 10, 2018.

UPDATE at 11:20 a.m. PST November 10, 2018:

At 11:20 a.m. PST Saturday the air quality north of Sacramento was Unhealthy to Very Unhealthy.

At this time the air quality web site AirNow.gov is down. Perhaps because so many smoke-affected people are trying to access it.
