@fox13seattle: Smoke will likely become more noticeable across Western Washington through Wednesday as offshore winds send wildfire smoke across the Cascades. Exactly where the thickest smoke settles will vary from day to day, but some of that smoke is expected to mix down to the surface during afternoons. Air quality could reach unhealthy levels in spots. Air quality conditions should begin improving later this week as winds gradually shift back onshore, helping push cleaner marine air into Western Washington.
