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: The weather pattern over the Southwest U.S. this week will be quite different than last week's. Last week, we had a strong high pressure solidly situated over the region; this week, high pressure over the region today will give way to a flatter, west-east wind flow pattern by tomorrow. Furthermore, the main weather focus for this week will be breezy winds out of the west. Afternoon winds currently look to be the breeziest on Tuesday and Wednesday. Lighter winds then return by Friday. Air quality-wise, ozone is expected to be its highest today due to the said high pressure. Light winds will enable ozone to accumulate this afternoon. However, after today, the breezy winds are expected to help disperse ozone and limit its daytime accumulation. Regarding particulates, both PM-10 and PM-2.5 are forecast to remain in the Good Air Quality Index category through at least Friday--Arizona won't be under an active monsoonal pattern until perhaps early next week. But, still can't rule out the off chance of local, loose dust being kicked up by the breezier winds. Check back tomorrow for the latest. Until then, have a good day! –M.
