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 17th 2016 through Monday, October 24th, 2016 PM-2.5: 24-hour Fine Particulate concentrations are expected to be mostly Good Low Moderate. FORECAST DISCUSSION: A warm front has lifted northward through the state, on Monday, to provide unseasonably warm weather for the first two days of the work week. I expect temperatures to make it into the mid-70’s and maybe a touch higher if the clouds break and we see some prolonged sun. Although fine particulate levels are starting the week generally Good, the ample moisture and warm temperatures could boost concentrations into the Low Moderate range. A cold front will push through the state late Tuesday and clean out any Low Moderate particulates. High pressure will build in during Wednesday for the nicest day of the work week. A low pressure cell will move eastward across the Ohio Valley during the Wednesday night and Thursday time frame. When that system clears the Midwest, strong northerly winds will sweep into the region providing colder but clean air for the weekend with cooler daily high temperatures in the 50’s. EXTENDED FORECAST: Another moderating temperature trend will begin late in the weekend and into early next week Forecast updated by Jim Haywood: Monday, October 17th, 2016 Next forecast update: Monday, October 24th, 2016
