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 25th, 2017 through Friday, September 29th, 2017 Ozone: Ozone concentrations will mostly range from middle to upper Moderate with isolated USG possible Monday and Tuesday; levels improve to Good the rest of the week. PM-2.5: 24-hour Fine Particulate concentrations will remain Moderate through Tuesday, improving to Good Wednesday through Friday. FORECAST DISCUSSION: The unseasonably hot weather pattern will hold for two more days. The highest 8-hour ozone concentrations for the most part have remained middle to high Moderate and that trend will continue through Tuesday. Some areas have, however, experienced high hourly ozone levels in the USG range during the afternoon and this trend will also continue. So, even though 8-hour ozone should remain Moderate, please take precautions and limit outdoor activities if you are sensitive to high pollution levels. Based on current trends, the highest ozone concentrations Monday and Tuesday will again be in the eastern/southeastern portion of the state and/or along the Lake Michigan shoreline. Fine particulate levels will continue running in the Moderate range. Early Wednesday a weak cold front will move through bringing us back to more seasonable temperatures. This front will also help improve air pollution levels. Readings may be Moderate, generally for fine particulate, in the east on Wednesday, but the northwesterly winds behind the front will bring a return to Good levels by Thursday. EXTENDED FORECAST: A second cold front will pass the state Friday bringing with it some precipitation and even cooler air in its wake. Air pollution levels for the end of the week should be Good for both ozone and fine particulate.
