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, October 24th, 2016 through Friday, October 28th, 2016 PM-2.5: 24-hour Fine Particulate concentrations will remain mostly Good through Friday. FORECAST DISCUSSION: A cool northwest wind will be in place through Tuesday thanks to low pressure positioned northeast of the state, and high pressure to our west. The cooler air moving over the warmer lake waters will produce scattered lake effect showers on Monday/early Tuesday in the most prone northwest flow areas of the Upper Peninsula and Northern Lower. It’s even possible for some of these showers to fall as snow showers, or to have some snowflakes mixed in; especially in Upper Michigan. By mid-week the next weather system approaches the state. This system will bring decent chances for rain Wednesday/early Thursday as it tracks near the southern Michigan border. After a cool and wet Wednesday, conditions dry out Thursday as high pressure moves back in. Northwest winds should keep fine particulate in the Good range Monday and Tuesday. Winds go southeast, then northeast Wednesday, into Thursday as the storm system moves through. This wind flow, coupled with rain showers, will keep fine particulate levels Good. High pressure is east of the state later Friday producing a southerly wind ahead of the next weather system. A few Moderate fine particulate readings are possible Friday. EXTENDED FORECAST: Rain moves back in the forecast later Friday/early Saturday as low pressure moves through. High pressure builds back in Saturday and Good fine particulate is expected. The high moves overhead Sunday and lighter winds may mean some Moderate fine particulate levels.
