Forecast Discussion: Current conditions: A cold front has slipped to the south of the area this Tuesday afternoon. With a clean northerly flow, fine particulate and ozone are down in the good range. The cold front will come back northward later on tonight, and bring a shower later on. *** Wednesday's forecast: Rather cloudy during the day Wednesday with showers and thunderstorms, and some of these can produce heavy rains. Because of the cloud cover and rainfall, ozone and fine particulate will be well down in the good range. *** Extended forecast: Rain and clouds will move to the south of the area on Thursday, but there may not be enough sun to bring ozone out of the good range. A north to northeasterly flow of clean air will keep fine particulate concentrations low as well. A slow moving area of low pressure coming out of the Midwest will mean more unsettled weather for the area later Friday into Saturday, and the extensive cloud cover will not be favorable for ozone formation.---McAuliffe
