All pollutants stayed in the Good AQI range yesterday. Looking ahead, we expect ozone to continue hovering around the upper Good to lower Moderate range this week.
Switching to particulates, we did see some brief dust move through this morning from thunderstorm outflows, which will cause PM10 and PM2.5 to reach the Moderate AQI category today. After today, we don't expect any significant dust storms. As a result, we are forecasting PM10 and PM2.5 to return to the Good AQI category through the remainder of the week.
