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, November 20th, 2017 through Monday, November 27th, 2017 PM-2.5: 24-hour Fine Particulate concentrations will generally be Good through the period; the best chance for low-Moderate levels would be Thursday into Friday. FORECAST DISCUSSION: High pressure dominating Monday tracks east Tuesday as a system north of the state brings a cold front through. Gusty southwest winds Monday turn northwest Tuesday as the front passes. Wind speeds will be high enough Monday to hamper a significant increase in fine particulate; readings should average Good. Northwest winds developing Tuesday could bring accumulating lake effect snows to the prone areas of northern Michigan; however, the cold/clean air will keep fine particulate Good. Winds weaken Wednesday as high pressure moves closer to the state but a northwesterly flow continues; Good fine particulate is expected. A weak system is forecast to move north through Ontario on Thanksgiving which may bring scattered snow showers to northern parts of the state. Weaker winds could allow for an increase in fine particulate, but this should be confined to the southern portion of the state. Fine particulate will be mostly Good with scattered low Moderates possible in southern locations. Another storm system approaches by Friday and southwest winds will be increasing during the day. Some low-Moderate fine particulate may linger in the southeast Friday; otherwise, Good levels can be expected. EXTENDED FORECAST: Northwest winds develop early Saturday after the cold front passes and extended forecast models show northerly winds continuing into early next week. Fine particulate is expected to remain Good through the period... Forecast updated by Stephanie Hengesbach: Monday, November 20th, 2017 Next forecast update: Monday, November 27th, 2017
