Forecast Discussion:

No air quality issues are expected through the forecast period. Good ventilation from a low pressure system over the west coast will limit any accumulation of air pollution in the area. We may also see some isolated showers and thunderstorms this weekend associated with the low, but we don't anticipate rainfall amounts to be that high. Additionally, the breezy easterly winds will continue for the next few days, with Saturday expected to have the strongest winds. Overall, both ozone and PM10 are forecast to stay in the Good AQI range through the forecast period.
