O3 = Ozone, PM10 = Particles ≤ 10 microns, PM2.5 = Particles ≤ 2.5 microns

Forecast Discussion:

A trough is currently pushing into the west coast and will be passing through the northern part of the state on Thursdays and Friday. This will provide good ventilation over the region, helping keep ozone and particulate levels down. Then, another weather system will move through the area Sunday and early next week. This one will be a deeper system and more likely to bring rain to the area. Again, this will help keep ozone and particulates levels low. Overall, both ozone and PM10 are forecast to remain in the Good AQI range through the forecast period.
