Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)

Forecast Discussion: Current conditions: Southwest winds are sending rather warm air into the area this Friday afternoon. With a good deal of sunshine, ozone levels are getting well into the moderate range once more, though they will not peak as high as Thursday's levels. Clear to partly cloudy tonight with low temperatures falling back into the middle 60s. *** Saturday's forecast: Rather warm and humid for the day Saturday, with afternoon and evening thunderstorms likely. The arrival of convective activity should hold ozone to the moderate range, and fine particulate will also remain moderate as well. *** Sunday's forecast: More clouds than sunshine for the day Sunday with a couple of showers and thunderstorms around. Once again, fine particulate and ozone will end up in the moderate range, with high temperatures reaching into the middle 80s. *** Memorial Day forecast: Turning out partly sunny and warm for Memorial Day with just a pop up shower---most of the time will be rain free as temperatures warm into the lower and middle 80s. Moderate air quality will prevail with the lack of surface flow. *** Tuesday's forecast: Times of clouds and sunshine Tuesday with a warm afternoon, and ozone production could ramp up higher into the moderate range with enough sun. Fine particulate will stay moderate as well. *** Extended forecast: The mid to late week period looks to be more unsettled with increasing chances for showers and thunderstorms as a tropical system teams up with low pressure coming across the Midwest. The chances for elevated ozone levels will remain low, but fine particulate may be upper good to lower moderate, depending on how much rainfall there is.---McAuliffe
