All pollutants stayed in the Good AQI category yesterday, but there was some brief dust yesterday evening with thunderstorm activity around the area. 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.
