Forecast Discussion: Showers and a thunderstorm or two continue building across the area this Monday afternoon. The convection is limiting ozone to the good range. A small area of high pressure builds in for Tuesday and brings increasing ozone concentrations, perhaps into the lower moderate range in spots. As a frontal boundary oscillates northward and southward across the northern Mid-Atlantic states Wednesday, look for numerous showers and a thunderstorm. Ozone will be held in check to the good range. Less convective coverage is expected Thursday into Friday, so this means ozone concentrations will be on the rise once more. However, most locations should remain in the upper good range.---McAuliffe
