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: FORECAST SUMMARY: Monday, August 14th, 2017 through Monday, August 21st, 2017 Ozone: Ozone concentrations are expected to be Good to Moderate for the forecast period. PM-2.5: 24-hour Fine Particulate concentrations are expected to be mostly Good through the forecast period. FORECAST DISCUSSION: The Tuesday/Wednesday time frame is likely to be the best chance for any ozone creep during the work week and that will be restricted to the Southeast Michigan area. Calm winds will allow some accumulating stagnation and if any prolonged sunlight is present, we could see ozone numbers building into the Moderate range. The chances are less likely on Wednesday, however, as a warm front lifts northward and the chances for clouds and shower activity begin to increase. Wednesday night into Thursday will show increased humidity as southern Gulf air streams into the state but overcast skies will prevent any significant ozone development. Fine particulates could begin creeping up but brisk winds should keep the atmosphere well mixed. Light winds, during the weekend and into Monday, could lead to more stagnation and ozone growth into the Moderate range in the southeast Michigan area. The lake shore counties should not have any issue as any winds that do show up should be easterly in nature. EXTENDED FORECAST: Air Quality is expected to be mostly Good to Moderate going into the next work week. Forecast updated by Jim Haywood: Monday, August 14th, 2017 Next forecast update: Monday, August 21st, 2017
