Forecast Discussion: At 2 p.m. EDT this Tuesday afternoon, high pressure has produced plenty of sunshine and warmth across the area. Clouds increase by later on Wednesday, and there will be showers and a thunderstorm late in the afternoon into the evening. Clouds and convection will act to reduce ozone to the good range. Cooler and drier air will move in behind the cold front for later on this week, and with ample mixing and the presence of dry air, ozone levels will remain low through Saturday.---McAuliffe
