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: Most of the Valley saw good air quality yesterday. The main exception was (and has been) areas south and west of the Phoenix metro area, which finished the day in the Moderate Air Quality Index (AQI) category for PM-10 and PM-2.5. Some areas in central Phoenix also saw some elevated particulate levels during the day. Early this morning, particulate levels were running much lower in areas south and west of the Phoenix metro area than other mornings this week. However, since 5 or 6 AM, they have been starting to make a rebound. Today, high pressure over the state will result in mainly light wind conditions, which will favor accumulation of PM-10 and PM-2.5 in the aforementioned areas. But, elsewhere around the Valley, particulate levels should remain relatively low. This weekend, the main story weather-wise will be a cooling trend and--should we say it?--chances for rain, courtesy of low pressure swinging through the region. High temperatures will fall into the 60s Saturday through at least Monday; rain chances are currently looking to be on Sunday. In all of this, winds are expected to remain mostly light. Air quality-wise, PM-2.5 is forecast to increase this weekend, accounting for the light winds and the potential for more fireplace usage--we are getting closer to the holidays and it will be colder. PM-10 typically decreases over the weekend as work week activities cease or lessen. But, PM-10 can still be elevated in the usual areas south and west of the Phoenix metro area. If rain pans out on Sunday, air quality would improve (and PM-10 and PM-2.5 AQI values could end up being much less than forecast for Sunday). By Monday, high pressure will start building over the region again. This will promote calm weather conditions in the Valley through at least Tuesday. Particulate levels should thus increase again. Check back on Monday for the next Phoenix air quality forecast. –M. Graves http://www.azdeq.gov/programs/air-quality-programs/air-forecasting Last Update: Friday, December 15, 2017, 9:25 AM
