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: Ozone did end up exceeding the federal health standard yesterday at the Mesa monitor while most of the monitoring network ended up in the mid/upper-Moderate range. We still have the high-pressure ridge over the region causing the above normal temperatures. However, a traversing trough well to the north is causing the ridge to break down. The increased pressure gradient will result in breezier conditions the next couple days. Breezes beginning later this afternoon will hopefully be enough to prevent ozone exceedance today. Tomorrow, winds should pick up earlier, which should keep ozone levels down even further. Conditions will begin to calm back down on Friday, this will likely cause ozone levels to trend back up Friday through the weekend. The winds the next couple days are not forecast to be enough to kick up dust, and therefore we will be keeping particulates in the Good range. Check back tomorrow for more. Until then, have a good day! –R. Nicoll Last Update: Wednesday, May 24, 2017, 8:23 AM
