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, August 21st, 2017 through Monday, August 28th, 2017 Ozone: Ozone concentrations will be Good to Moderate Monday, then mostly Good the rest of the forecast period. PM-2.5: 24-hour Fine Particulate concentrations will also be Good to Moderate Monday with generally Good readings the rest of the period. FORECAST DISCUSSION: One more summer-like day is in store for Monday before cooler temperatures move in which will last through the week. Some clouds are expected Monday but a warm southwest flow will allow pollution to increase. Ozone is expected to get into the Moderate range and a small chance exists for a monitor or two in the southeast to hit low-end USG; however, this threat is not high enough to warrant an action day. Fine particulate will also be Moderate Monday, especially across the southern half of the state. A cold front will bring showers and storms Monday night into Tuesday with conditions drying out after the boundary passes. Low-end Moderate fine particulate may linger in the southeast Tuesday; otherwise, pollution levels will improve to the Good range for both pollutants. High pressure sinking in from the northwest will be the dominating weather feature for the rest of the week. Cooler temperatures on a northerly wind will keep both ozone and fine particulate Good through Friday. EXTENDED FORECAST: Extended forecast models show high pressure moving overhead Saturday, and then to our east Sunday and Monday. Weaker winds will turn a bit more southerly Sunday and a weak system could bring precipitation Monday. Upper level temperatures remain low during the period, but high temperatures look to increase further into the 70s. Based on the current forecast, I’m expecting pollution to generally remain Good with only a small chance for Moderate ozone and/or fine particulate Sunday or Monday. Forecast updated by Stephanie Hengesbach: Monday, August 21st, 2017 Next forecast update: Monday, August 28th, 2017
