Forecast Discussion: As of 2 p.m. EDT this Thursday afternoon, rain and thunderstorm activity is affecting the area as a stationary front is draped just to the south. Ozone is being kept down in the good range as a result. Rain will end later this evening with areas of fog later on. Clouds and a little sunshine, warm, and humid for Friday---a shower or thunderstorm may still develop. The limited amount of sunshine will hold ozone values at the top end of the good range. Another wave of low pressure then comes out of the Ohio valley and brings another round of rain and thunder for the day Saturday. Again, ozone concentrations will be on the low side.---McAuliffe
