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: Current Conditions: As of 2 PM on Wednesday, partly cloudy skies prevail over the region as an area of high pressure continues to control our weather. This high, which is situated directly overhead (across the northern Mid-Atlantic), is not only controlling the cloud cover but also the winds. Right now, with winds remaining light, temperatures have made their way into the 70s. The cooler than normal temperatures along with the low moisture levels across the area have been enough to hold ozone within the good threshold today. Expect the ozone to increase tomorrow as warmer and slightly more humid air moves in. *** Thursday's Forecast: So for Thursday, expect mostly sunny skies in the morning to give way to partly cloudy skies by the afternoon as the area of high pressure, which was over the region on Wednesday, moves eastward into the western Atlantic. The counterclockwise flow around the high will steer our winds out of the southwest during the day, forcing temperatures and humidity levels to increase. In fact, afternoon highs are expected to peak in the low to mid 80s. The combination of sunshine and warmer temperatures should be enough to cause ozone to rise. It will be the lower background levels (readings moving into the region) that will limit levels to near the good / moderate threshold. --Nolan
