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, May 22nd, 2017 through Tuesday, May 30th, 2017 Ozone: Ozone concentrations are expected to be Good throughout the forecast period. PM-2.5: 24-hour Fine Particulate concentrations are also expected to be Good to Low Moderate throughout the forecast period. FORECAST DISCUSSION: Monday may be the driest day of the forecast period as a high pressure ridge moves through the state. During Tuesday, a stalled low pressure cell, located over the southern Lake Michigan area, will provide clouds and precipitation that will keep ozone formation in check. We may see some slight fine particulate creep, though. A deeper low pressure cell will form over Kentucky during Wednesday that will provide easterly winds for the state and the potential for a significant rain event, especially closer the Indiana border area as it moves northeastward. We may see a brief period of clearing on Friday with a surface high pressure ridge moving over the region. They may be a small low pressure cell invading that ridge, late Friday, which may generate some clouds and shower potential for the start of the holiday weekend. The holiday weekend looks to be cool to normal temperatures with some brief sky clearing on Saturday and then more scattered rain events through the remainder of the weekend. As for Air Quality, there is no real threat of elevated ozone, although we may see a little creep if the sun breaks out on Saturday. Fine particulates should also be mostly Good with a small chance of Low Moderates on Tuesday and Saturday. EXTENDED FORECAST: Air Quality is expected to be mostly Good going into the next work week. Forecast updated by Jim Haywood: Monday, May 22nd, 2017 Next forecast update: Tuesday, May 30th, 2017
