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, September 18th, 2017 through Wednesday, September 20th, 2017 Ozone: Ozone concentrations are expected to be Good to Moderate for the forecast period. PM-2.5: 24-hour Fine Particulate concentrations are also expected to be Good to Moderate through the forecast period. FORECAST DISCUSSION: The last week of summer will feel more like the middle of summer as mid/late week temperatures climb into the mid-80’s. The interesting question is what that will mean to our regional ozone production at a time when we normally see the ozone season winding down. We begin the week with winds transitioning from northerly to easterly. That should keep us mostly Good although southeast Michigan will likely creep into the Moderate range later Tuesday. Things get a bit more complex by mid-week. Surface winds become south to south-southeast. With the increased humidity and temperature, I do expect both ozone and particulate levels to begin creeping up throughout the state. With the surface winds staying in the mostly southerly direction, any elevated ozone over Lake Michigan should stay mostly over the lake. But it is a safe bet that we will be seeing solidly Moderate concentrations along the lake shore as well as southeast Michigan. Since the predicted wind patterns are causing the region concerns during mid-week and possibly into the weekend, the regional forecasters will convene on Wednesday and discuss the possibilities for Air Quality issues. EXTENDED FORECAST: Air Quality is expected to be mostly Moderate going into the end of the work week.
