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)

Forecast Discussion: Current conditions: A strong northwesterly flow around an area of high pressure centered over the Tennessee valley is bringing very breezy conditions this Friday afternoon. With the strong winds, fine particulate and ozone have been held to the good range. Dry weather will continue into Saturday, then an advancing frontal boundary slipping out of the Great Lakes slows down and stalls out close to us later Sunday into Monday, leading to a return of unsettled conditions. *** Saturday's forecast: As high pressure slips off of the North Carolina coast Saturday, winds will shift into the southwest. There may be enough sunshine to bring ozone close to the lower moderate range in a few spots, but fine particulate averages should be in the good range. *** Sunday's forecast: A slow moving front will approach the area Sunday, with increasing chances for showers and a thunderstorm. The cloud cover and convection will suppress ozone formation, and fine particulate will be in the good range as well. *** Monday's forecast: A stationary front will still be close by for the day Monday, continuing the chance for showers and thunderstorms, with the heaviest coming late in the afternoon/early evening. Ozone will continue to be hampered by the persistent cloud cover, and fine particulate once again will average in the good range. *** Extended forecast: High pressure will try and sneak into the area from the north Tuesday into Wednesday, so there may be a brief respite from the wet weather. A warm front coming in Thursday may bring back late day thunder. The best chance for moderate air quality will come Tuesday into Wednesday as winds lighten along with added sunshine.---McAuliffe
