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: Low pressure located over the Delmarva peninsula is slowly moving to the north-northeast out to sea this Wednesday afternoon. Rather cloudy and breezy this evening with a couple of showers, then chillier with clearing later on. *** Thursday's forecast: Periods of clouds and sunshine for the day Thursday with a seasonably mild afternoon. Enough low level mixing and dry air should keep fine particulate in the good range as temperatures max out in the lower to middle 60s. Clouds will increase and thicken Thursday night. *** Extended forecast: A fast moving area of low pressure will bring the area a couple of showers during the day Friday, and the rainfall coupled with low level ventilation will maintain PM2.5 in the good range. Rather cloudy, breezy and cool Saturday with a couple of showers, and fine particulate will remain in the good range. A large area of high pressure then builds in Sunday and settles south and southeastward as we move on into the early to middle part of next week. A shift in winds to the southwest will spell a summerlike warm up as we head on into the middle of the week. With the influx of warmer and more humid air, we will see an increase in both ozone and fine particulate concentrations during the first days of May.---McAuliffe
