Forecast Discussion:
Once again, ozone ended up in the Moderate AQI category yesterday, while PM10 and PM2.5 stayed in the Good range. We are not forecasting any significant changes to the weather and air quality over the coming days. There will continue to be isolated to scattered showers and thunderstorms each afternoon with temperatures reaching around 100 degrees each day.For ozone, with the weather pattern we've had recently, there tends to be enough atmospheric mixing and cloud cover to prevent ozone levels from reaching too high, but not enough to significantly lower ozone concentrations. With similar conditions expected to continue, we are forecasting ozone levels to stay in the low-to-mid Moderate range.
As for particulates, the recent rains from the daily showers and thunderstorms has stabilized the soils in the region, which should prevent any significant dust. Additionally, more rain from daily showers and thunderstorms is likely, which should continue to keep particulate levels low. Therefore, we are forecasting PM10 to stay in the Good AQI range through the forecast period. PM2.5 is also forecast to stay in the Good AQI range, however, there will likely be a slight increase Monday evening with firework celebrations for Independence Day.
