AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: The main weather story for this weekend is that the monsoon will ramp up again due to moisture increasing across the state. Particularly, the combination of greater moisture in southeast Arizona and upper-atmospheric winds out of the southeast will provide opportunities for thunderstorms to move toward and develop over the Valley from the southeast. Nevertheless, thunderstorms and thunderstorm outflow winds are possible from multiple directions (e.g. south, southeast, east, and northeast). Thunderstorm and rain chances will exist for the Valley each day through the weekend and possibly into the next work week. Air quality-wise, ozone will remain the primary pollutant of interest as it could potentially reach the Moderate Air Quality Index (AQI) category each day. However, ozone will strongly be dependent on thunderstorm activity. Any cloud cover, rain, and/or outflow winds would limit ozone production. If cloud cover and/or rain are widespread enough, ozone could remain in the Good AQI category Valley-wide. PM-10 is forecast to stay in the Good AQI category. Check back on Monday for a look ahead at next week's weather and air quality. Until then, have a great weekend! –M. Graves Last Update: Friday, July 28, 2017, 9:23 AM
