Forecast Discussion: Current conditions: At 2 p.m. EDT this Thursday afternoon, a stationary front was draped across the northern Mid-Atlantic. A wave of low pressure accompanied by rain and thunderstorms will move along this this afternoon and tonight. While ozone levels are in the high moderate range presently, these will come down greatly towards evening. The intensity of the rain will also force PM2.5 down into the good range overnight. *** Friday's forecast: Morning rain and a thunderstorm, then some sunshine will appear by the afternoon. This will act to spawn more late day and evening thunderstorms, but coverage will not be as great as early in the day. With more clouds than sunshine, ozone levels will remain in the upper good range, and fine particulate may also remain good as well. *** Extended forecast: Another area of low pressure rides along the stalled out front and brings more widespread rain and thunder for later in the day Saturday. Both ozone and fine particulate will remain in the upper good range. The weather remains unsettled Sunday into Monday with mostly afternoon and evening convection. This will act to limit ozone formation on these days, but with less rain and more humidity, fine particulate could rise to moderate levels. More moderate air quality with hotter afternoons is in store by the middle of next week as a ridge of high pressure coming out of the Plains reestablishes itself across the eastern part of the nation.---McAuliffe
