Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, very warm and humid conditions prevail across the region with scattered thunderstorms also developing. Parts of the area will receive a thunderstorm this afternoon into this evening. The developing storms are acting to keep ozone levels in the lower moderate range this afternoon. Fine particulate remains solidly in the moderate range with high humidity. A cold front will pass later tonight into early Friday morning. Mostly cloudy later on tonight with a shower and areas of fog. Lows in the middle to upper 60s. *** Friday's forecast: Periods of clouds and sunshine for the day on Friday. Enough low level moisture will bring a continued chance for a shower or thundershower. Ozone levels will only rise into the lower moderate range, with fine particulate also remaining low moderate. Afternoon temperatures in the middle 80s. Turning out partly cloudy Friday night with lows in the middle 60s. *** Extended forecast: Clouds will yield to sunshine for the day Saturday with high pressure building in from the north and east. Fine particulate and ozone will improve to the good range with the cleaner air mass. Upper good to lower moderate air quality will continue for Sunday with high pressure overhead. Fine particulate and ozone will deteriorate into the moderate range by the early part of next week with mostly dry conditions, very light winds and temperatures well above normal. By later on next week, a stronger cold front will move through, bringing cooler and more seasonable temperatures into the region with good air quality.---McAuliffe
