The highest AQ index in Arizona (as of 23:00 MST) is currently the Phoenix area. Particle Pollution (PM2.5) is measuring at 115 (Unhealthy for Sensitive Groups). This means members of sensitive groups may experience health effects. The general public is less likely to be affected.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Phoenix area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.

High pressure is now over the region, which should bring nice temperatures through the week. We expect mostly sunny skies, light winds, and pleasant temperatures the next several days. As for the air quality, PM10will be locally driven, with highest concentrations during the morning hours. PM10 is forecast to improve a little over the weekend with less dust-generating work activities. On the other hand, PM2.5 will likely increase over the weekend with increased fireplace usage. Overall, PM10 and PM2.5 are forecast to mostly stay in the Moderate AQI category through the forecast period. As for ozone, it is too late in the year for any concerns. Therefore, ozone is forecast to stay in the Good category through the forecast period.
