The highest AQ index in Arizona (as of 3:00 MST) is currently the West Pinal area. Particle Pollution (PM10) is measuring at 68 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
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.

It was a nice change weather-wise in Phoenix this weekend! While Sky Harbor officially only got a trace of rain, other locations across the Valley saw measurable rain, with the big rainfall winners being around the McDowell Mountains, where several gauges saw over a half inch of rain. If you didn't get rain, everyone is feeling the cooler air this morning, with most locations in the 40s.
The system that brought this active weather to the region will move east out of the state today, with a weak area of high pressure building in behind it. This pattern will be short-lived as another system drops into Arizona from the north Wednesday into Thursday. Due to this system dropping down from the north, it will have very little moisture, so the main impact will be an increase in northerly winds on Wednesday and Thursday with no chance of rain. This system will also bring more cool air with it, with afternoon high temperatures forecast to be in the upper 60s to low 70s all week, well below the average of around 82 degrees.
Regarding air quality, the active weather really helped to clear the airshed, with PM-10 (dust) and PM-2.5 (smoke) levels running nice and low this morning. As a result, expecting all pollutants to be in the Good AQI category today. With cool morning temperatures and lighter winds tomorrow morning and again Wednesday morning, expecting values to increase quickly starting tomorrow.
Have a great Monday!
