Forecast Discussion:

Once again, all pollutants ended up in the Good AQI range yesterday. Looking ahead, ozone levels are forecast to trend up into the Moderate AQI category as a ridge strengthens over the region. As for particulates, PM10 and PM2.5 levels are forecast to stay in the Good AQI range now that thunderstorm activity has quieted down and soils are stable from the recent rain.
