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: Today will be windy and warm ahead of an approaching system with a cold front. Winds will be out of the southwest. By tomorrow, a cooler air mass will be in place over Arizona, resulting in high temperatures around normal (or maybe slightly less) for the Tucson area. Winds will be weaker and out of the northwest. Then by Sunday, winds will become easterly, in addition to drier and warmer air over the region once again. High pressure will dominate Sunday through at least Tuesday, resulting in highs reaching the mid to upper 90s by Monday. Easterly winds are expected through at least Tuesday. Air quality-wise, ozone is forecast to increase on Saturday due to the northwesterly winds, which can transport ozone from the Phoenix area to southern Arizona. Ozone is thus forecast in the Moderate Air Quality Index (AQI) category. Ozone levels are then expected to decrease by Sunday with the easterly winds. The PM-10 forecast is a little more uncertain, as it depends a lot on local, weekday activity in the Rillito area. Daytime winds may help to limit overall accumulation of PM-10 early next work week, particularly Tuesday. Monday is currently forecast to see the highest PM-10 levels (Rillito). Check back on Monday for a look ahead at next week's weather and air quality. –M.
