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)

Forecast Discussion: We’ve got an active weekend ahead of us as moisture levels continue to increase in the Valley. The threat of thunderstorms will become more and more apparent as we head deeper into the monsoon. Over the last week and a half, stagnation was the primary culprit for the excessive ozone levels. However, moving forward, PM-10 will take the spotlight. Starting Saturday afternoon, thunderstorms will take form near the higher terrain and eastern Arizona. Outflows from these storms do hold the potential to traverse over Pinal County and reach the Phoenix Metro area around late Saturday night and early Sunday morning. Therefore, blowing dust is certainly possible with a bit of a haze lingering around early morning Sunday. That same day, sometime during the afternoon hours, more convective cells will pop up over central Arizona, possibly reaching the Valley around Sunday evening. Therefore, additional blowing dust possible. Even though the Valley could see some rain on Sunday, it’s likely these outflows will hit us first and cause dust issues before any rainfall can remove airborne dust. Check back on Monday for a look ahead at next week's weather and air quality. Until then, have a great weekend! –P. Patel Last Update: Friday, June 23, 2017, 9:36 AM
