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: Wednesday, September 20th, 2017 through Thursday, September 21st, 2017 Ozone: Ozone concentrations will be range between Good and Moderate. PM-2.5: 24-hour Fine Particulate concentrations will also be in the Good to Moderate range. FORECAST DISCUSSION: A weakening front moving into the area Wednesday night into Thursday will bring small chances for showers and storms. This boundary dissipates over the region into Friday and then high pressure makes a return as the dominating weather feature through the weekend. Over the next two days, warmer than normal temperatures will be in place and readings will also be increasing at upper levels. Surface winds seem to have more of a south/southeasterly component which generally keeps higher ozone levels along the west shoreline of Lake Michigan. Some clouds and scattered precipitation with also be around with the dissipating frontal boundary; this weather scenario should keep both ozone and fine particulate from reaching higher than Moderate either Wednesday or Thursday. The high sets up east of the state Friday continuing the summer-like conditions on the first official day of fall. The expected weather-set up will be something to keep an eye toward the end of the week. Weather conditions are conducive for ozone development; however, considering less daylight this time of year it may be hard for high levels to hold long enough to reach the USG threshold. EXTENDED FORECAST: High pressure lingers east of Michigan through early next week making the threat for increased pollution a possibility… Forecast updated by Stephanie Hengesbach: Wednesday, September 20th, 2017 Next forecast update: Thursday, September 21st, 2017
