For Fri-Mon (Sep 4-7) We'll have mostly GOOD to MODERATE air quality this weekend. Late this afternoon and early evening, we may have some smoke moving into the Cascades and sneaking through the passes. Some areas could reach MODERATE or UNHEALTHY FOR SENSITIVE GROUPS for a few hours. Overnight and into Saturday, winds should shift back to westerly and mix the smoke and push it back east. This pattern could repeat again Saturday evening and Sun. Monday should have good westerly winds and GOOD air quality.
