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)

Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, there are mostly sunny skies and warm temperatures across the area as high pressure continues to control the weather picture. Summer will stick around into the weekend despite the calendar saying fall will arrive at 10:21 a.m. EDT Friday morning. Strong high pressure, both at the surface and aloft, will keep air motion in the boundary layer limited over the next few days, and the summerlike warmth will permit ozone to continue to go well into the moderate range. Fine particulate averages are likely to be well into the moderate range due to the lack of air movement and morning inversions. For tonight, we will have a mostly clear sky with fine particulate becoming elevated across the area. *** Friday's forecast: Mostly sunny skies with unseasonably warm air will close out the workweek Friday with afternoon temperatures in the middle 80s. Ozone and fine particulate will end up in the moderate range again, with the highest PM2.5 concentrations in the morning with the expected inversion. *** Extended forecast: Elevated levels of pollutants are likely to continue into the weekend with recirculating air as well as sunshine and unseasonable warmth. The mercury will go well into the 80s over the weekend, and some places may touch the 90 degree mark Sunday into Monday. Air quality will continue to be moderate, and we will even have to watch for the possibility of code ORANGE ozone during the extended period.---McAuliffe
