Forecast Discussion: Current Conditions: At 2 p.m. EDT this Wednesday afternoon, very warm and humid conditions continue across the area with a scattering of showers and a thunderstorm. This convection is keeping ozone concentrations from rising no higher than the middle moderate range. Fine particulate remains in the middle moderate range. A cold front passing through later on Thursday will bring another chance for convective activity. Drier air will then result in improved air quality over the upcoming weekend. Tonight will bring warm and sticky conditions with lows in the upper 60s. *** Thursday's forecast: Thursday will bring times of clouds and sunshine with another chance for afternoon and evening thunderstorms across the area with a cold front approaching from the north and west. Afternoon temperatures in the middle 80s. *** Extended forecast: A cold front will move through the area Thursday night and be just to the south of us for the day Friday. Friday will see clouds and a little sunshine with still the chance for a shower. Ozone will fall into the upper good range, but PM2.5 may remain moderate as winds remain light and low level moisture lingers. High pressure building in over the Labor Day weekend will bring dry weather. A little cleaner air moves in for Saturday, and both ozone and fine particulate will be in the good range. Moderate air quality may return quickly by early next week as the air stagnates and temperatures move well above normal. A stronger cold front may then affect the area for the latter part of next week.---McAuliffe
