Forecast Discussion: Current conditions: At 2 p.m. EDT this Thursday afternoon, rain and thunder were affecting the region as waves of low pressure ride along a stationary front draped just to our south. This activity will start decreasing by this evening, then mostly cloudy overnight with areas of fog. *** Friday's forecast: More clouds than sunshine for the day Friday with another round of showers and thunderstorms hitting the area by the afternoon. With this convection, ozone levels will not be able to get above the top end of the good range, but with high humidity, fine particulate may remain in the moderate zone. High temperatures will only reach into the lower 80s with only limited sunshine. *** Extended forecast: Another area of low pressure coming out of the Ohio valley will ride a stationary front on Saturday, and bring more shower and thunderstorm activity. Plenty of clouds will limit ozone to low concentrations, and even PM2.5 has a chance to remain good owing to heavier amounts of rainfall. More sunshine is expected Sunday into Monday with scattered thunderstorm activity each day. While ozone will continue to be limited in scope, the high humidity and less thunderstorm coverage may mean moderate levels of fine particulate. A strong upper level ridge of high pressure will make a comeback for the middle of next week with less chance for convection and fewer clouds, so ozone and fine particulate both will climb back to at least moderate levels.---McAuliffe
