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: Updated Thursday, February 27, 2020 High pressure is in control and a warm up in afternoon high temperatures will take place today and Friday. A weak and dry upper level trough will move into/through the area Friday/Saturday and bring an increase in high clouds on Friday. Accordingly the ridge of high pressure will flatten as a low pressure system begins to form in northern California over the weekend. It’s forecasted to mode southward through California and by Monday move eastward and into the state. The forecast models peg the higher amounts of precipitation over the higher elevations to our north and east and have maybe a tenth of an inch or so for much of the central and western portions of the County. It should be just enough precipitation in those areas to knock the PM10 levels down into the lower range of the good AQI category. The air quality forecast for the next several days is as follows, less winds and warmer temperatures today with winds that are favorable for ozone development and transport for central and southern areas of the County (low moderate AQI forecast for Casa Grande and Pinal Air Park monitoring locations). The winds this afternoon for northern areas of the County (Apache Junction and Queen Valley) are forecast to have a more northeasterly component and so aren’t expected to be as favorable for ozone levels rising enough to reach the moderate AQI category. Additionally on Friday the northern portions of the County are forecast to have southeasterly winds which is expected to inhibit the ozone formation and transport just enough to keep those locations from reaching the moderate category. However Pinal Air Park is expected to have winds that bring ozone and its precursors from the Tucson metro and so it has a low moderate forecast for Friday. More in the way of sunshine is expected on Saturday along with favorable transport winds during the afternoon and so all ozone locations are forecast to reach the low moderate range on the AQI scale. Check back tomorrow for an updated air quality forecast. Forecaster: S. DiBiase
