Forecast Discussion: At 2 p.m. EDT this Thursday afternoon, low pressure moving along a stationary front just to our south has resulted in rain and some thunder across the area. This activity will last into the evening before ending later with areas of fog. Clouds and a little sunshine and humid for Friday with a thunderstorm possible in the afternoon. Ozone will rise, but only to the top end of the good range. Lower concentrations of ozone are again likely on Saturday as another low brings another round of showers and thunderstorms to the area.---McAuliffe
