Forecast Discussion: Current conditions: At 2 p.m. EDT this Tuesday afternoon, an upper level area of low pressure continues moving away from the area to the northeast. A couple of thunderstorms may still be scattered across the area into this evening. Clearing will occur later on tonight with areas of fog. *** Wednesday's forecast: High pressure will bring a dry day for once, with more sunshine and low chances for rain. Ozone levels will respond into the moderate range, and a moderate inversion Wednesday morning may aid in fine particulate averaging in the moderate zone as well. Afternoon temperatures in the middle 80s. *** Extended forecast: More cloudiness moves back into the area later on this week. Thursday will bring more clouds than sunshine, and a thunderstorm is possible, mainly in the afternoon. Ozone levels will drop back to the good range, but fine particulate remains moderate with limited flow and mixing. A cold front coming through Friday will send additional showers and a thunderstorm across the area. Clouds and limited sunshine on Saturday, still the chance for showers. Air quality Friday into Saturday will improve to the good range.---McAuliffe
