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, March 12th, 2018 through Monday, March 19th, 2018 PM-2.5: 24-hour Fine Particulate concentrations will be mostly Good through the forecast period with chances for Moderates Saturday into Sunday. FORECAST DISCUSSION: Weak disturbances traveling in a northwesterly upper level flow will bring chances for scattered snow showers Monday into Tuesday, and then again late Wednesday into Thursday. Accumulations won’t amount to much, except for higher accumulations possible Monday and Tuesday across parts of the Upper Peninsula. At the surface, high pressure slides in early Wednesday with another high pressure area moving in Friday. Upper level ridging also moves in Friday with the ridge positioning itself overhead Saturday. This will produce sunshine and moderating temperatures for the end of the week. As for air quality, lighter winds Monday in the southeast may allow for a monitor or two to hit low-end Moderate for fine particulates; otherwise, levels remain Good. For the rest of the work-week, northwesterly winds at upper levels through Friday will keep fine particulate in the Good range. EXTENDED FORECAST: Weaker winds expected Saturday may allow fine particulate to reach low-end Moderate across parts of the state. Winds then turn southwesterly Sunday as the high slides east; this keeps the chance for Moderate fine particulate in the forecast. Weather models differ on the timing of the next weather system which could bring rain/snow back in the forecast as early as Sunday. Regardless of the weather forecast, a stagnant period of weather is not expected as we go into early next week; therefore, any possible increases in fine particulate will not be higher than low-mid Moderate.
