Forecast Discussion: Current Conditions: At 2 p.m. EDT this Tuesday afternoon, high pressure continues to bring plenty of sunshine and heat to the region. Ozone levels have risen into the upper moderate range with temperatures approaching the 90 degree mark. Fine particulate has also averaged well into the moderate range with limited mixing. Tonight will turn out mostly clear and hazy with fine particulate moving into Code ORANGE range later on. *** Wednesday's forecast: Times of clouds and sunshine on Wednesday, and with more moisture at low levels, an afternoon thunderstorm is possible. This will limit the formation of ozone to the middle moderate range. Fine particulate will average in the high moderate zone. *** Extended forecast: A cool front coming in from the north and west on Thursday will bring the likelihood of another afternoon and evening thunderstorm, and ozone will be limited to the lower moderate range with fine particulate well into the moderate zone. Things will cool a little over the Labor Day weekend with a new area of high pressure building in. Upper good to lower moderate air quality will be the rule on Friday, then moderate overall later on in the weekend with more sun than clouds and temperatures above normal early September values. A stronger cold front will bring cooler air and good air quality back around the middle of next week.---McAuliffe
