Forecast Discussion: Yesterday, ozone finished in the Moderate Air Quality Index (AQI) category at every ozone monitor around Tucson. Ozone was able to reach an AQI of 80 at the Saguaro Monument monitor. Elsewhere in the Tucson area, ozone remained in the 50s or 60s AQI. PM10 (dust) was able to reach the Moderate AQI category at the Rillito monitor, but remained in the Good category throughout the rest of the Tucson area.

Looking ahead, high pressure will remain in place over the Southwest this week. As a result, ozone is forecast to continue in the Moderate AQI category in Tucson each day of this forecast period. The main wildcard though will be thunderstorm chances, particularly today and Wednesday. Clouds, wind, and/or rain are expected to help limit ozone levels, at least through Wednesday. Ozone levels are then forecast to increase in the latter half of the week.

PM10 is forecast in the Good AQI category each day, but can't completely rule out the possibility of briefly elevated levels at the Rillito monitor.
