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.

Forecast Discussion: Current conditions: As a strong, summer like ridge of high pressure moves off to our east this Tuesday afternoon, southeasterly winds are freshening across the area. These winds have created enough dispersion to where fine particulate is down inside the good range, but temperatures in the middle 80s along with a good deal of sunshine have brought ozone to moderate levels in parts of the area. *** Wednesday’s forecast: Skies will remain partly sunny Wednesday with another warm afternoon. While light morning winds and a weak inversion will allow PM2.5 to be elevated some during the morning, lower afternoon levels will mean this pollutant’s overall concentrations will be in the upper good range. With the sunshine and warmth, ozone levels will also be in the upper good range. *** Extended forecast: Humid on Thursday with variably cloudy skies along with a shower or thunderstorm. Winds swinging around to the southwest mean PM2.5 levels might go moderate, but with more clouds than sun, ozone stays in the upper good range. A cold front approaching from the Ohio valley sends more showers and a thunderstorm our way Friday afternoon and evening, then winds turning into the northwest over the weekend bring cooler air and good air quality.---McAuliffe
