Forecast Discussion:

Ozone levels ended up in the mid Moderate AQI category yesterday, while PM10 and PM2.5 concentrations were once again very low yesterday. Looking ahead, we are not expecting any major changes to the weather. We are expecting the daily chances for thunderstorms to continue the next several days with this active monsoon weather pattern over the region.

The ozone forecast is a little more difficult than the PM10 and PM2.5forecasts, as a lot depends on the timing of winds and cloud cover from nearby thunderstorm activity. However in general, we expect ozone levels to hover around the mid Moderate AQI range through the forecast period. As for PM10 and PM2.5, the area has received a good amount of rain recently, and will likely continue to get more rain over the coming days. This will continue to keep the soils stable and limit any dust issues. Therefore, PM10 and PM2.5 are forecast to stay in the Good AQI range for the near future.
