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: Beneficial winds have lingered through the overnight hours and continue this morning. The timing is excellent for precluding stagnant inversions and pollutant buildup. Although winds are to gradually back down through the course of the day, final AQI readings in the Good air quality category are expected. The tight pressure gradient forcing breezy easterly winds locally is being instigated by strong surface high pressure over the southern Great Plains from an arctic outbreak. This feature looks to stay intact through today and weaken by Thursday. The gradient should relax and winds become less pronounced with time. Ultimately, we should have at least one more night of at least light but persistent easterly flow. The key is the persistent nature of winds to once again keep the air from becoming stagnant. Good air quality for tomorrow, too, because of this. Friday, a Pacific disturbance closes in on the area. Afternoon southwesterly breezes develop and maintain on Saturday when a dry cold front crosses the lower deserts. There is an opportunity for blowing dust in southeastern California and southern Arizona. This will be evaluated as we get closer to the event. Brisk temperatures and daytime northwesterly winds follow the frontal passage on Sunday. Per the latest, there are more indicators than otherwise for Good air quality in the Tucson area for the short-term. –J.
