Ozone and PM2.5 levels stayed in the Good AQI range, while one PM10 monitor reached the low Moderate category due to the localized activity we mentioned yesterday. Looking ahead we don't anticipate any significant issues. Decent ventilation and increasing cloud cover should keep ozone levels in the Good range. As for particulates, we aren't forecasting any winds strong enough to cause major issues. Therefore, PM10 and PM2.5 are also forecast to stay in the Good AQI range through the forecast period.
