Forecast Discussion: At 2 p.m. EDT this Monday afternoon, drier air was moving into the area with high pressure building in from the north-northwest. This has acted to bring ozone levels down to the upper good range. Ozone concentrations will rise a little for Tuesday, but may remain at the top end of the good range. Clouds and possible thunderstorms Thursday out ahead of a strong cold front may hamper ozone production on this day. Cooler and drier air sweeping in behind this front will bring good air quality for the late week period.---McAuliffe
