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)

Forecast Discussion: Updated Friday, February 17, 2017 The highest forecasted levels of PM10 are in the low to mid levels of the moderate AQI category today as an approaching upper level low pressure system ramps up the winds. The winds will reach gusts in the 20-25 mph range today and create pockets of blowing dust. More in the way of blowing dust will take place during the first half of Saturday as the wind gusts surpass 30 mph! Therefore the forecasted PM10 levels on Saturday will be in the good to mid moderate range on the AQI scale. Rain showers will overspread the area Saturday afternoon and continue Saturday night and into Sunday morning. Most areas are expected to received at least 0.25 to 0.5” of rain with higher locations receiving nearly an inch of rain! Therefore the PM10 levels will drop back into the good AQI category for Sunday through Tuesday. The PM2.5 and ozone levels will be in the good AQI category over the next several days. Forecaster: S.
