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.

Forecast Discussion: Current Conditions: At 2 p.m. EDT this Monday afternoon, a small area of high pressure is building into the area from the Ohio valley. Plenty of clouds and mixing are keeping ozone and fine particulate down into the good range. Tonight will turn out partly cloudy and chilly with low temperatures in the upper 40s. *** Tuesday's forecast: Dry weather will hold for the day Tuesday, with some breaks of sunshine allowing ozone to go close to the moderate range. Less mixing will also mean fine particulate is at the top end of the good range. Afternoon temperatures will climb into the middle 70s. *** Extended forecast: Clouds will be on the increase for the day Wednesday, with an area of rain to the southwest slowly moving towards the region. Ozone will remain in the good range, and increasing mixing should keep fine particulate concentrations from rising. Low pressure will bring showers and thunderstorms for Wednesday night into Thursday. As this low moves off to the northeast late this week, Friday will be breezy and cooler with clouds and a little sunshine. Saturday should remain dry with clouds and some sunshine, but with less wind. The next area of low pressure comes out of the Ohio valley to bring us the chance for more showers and thunderstorms Sunday into Memorial Day. Fine particulate and ozone concentrations will average in the upper good range Friday, but may reach the moderate range during the holiday weekend with less wind and rising temperatures.---McAuliffe
