Forecast Discussion:

The air quality in Tucson was pretty much as expected over the weekend. Ozone stayed in the mid Moderate levels, while PM10 and PM2.5 remained comfortably in the Good category. Looking ahead to this week, the monsoon ridge is forecast to remain firmly in place. As a result, there will continue to be daily chances for showers and thunderstorms in the area.

Looking at ozone, we do think there will be potential for ozone levels to get fairly elevated, but cloud cover and increased winds in the afternoons from nearby thunderstorms will hopefully prevent ozone levels from getting too high. We are forecasting ozone to hover around the mid-to-upper Moderate AQI range this week. As for PM10 and PM2.5, we don't expect any significant issues. Recent storm activity in the region has brought rain to the area, which is keeping the soils stable. Additionally, more rain is likely from storm activity through the week. Therefore, we are forecasting particulate levels to remain in the Good AQI category through the week.
