Forecast Discussion: At 2 p.m. EDT this Tuesday afternoon, drier air has moved into the area from the northwest and resulted in lower ozone values in spite of the sunshine and warm air. High pressure and light winds during the day Wednesday will allow ozone concentrations to move into the lower to middle moderate range. The weather pattern then takes a turn for the unsettled later on this week with areas of low pressure coming out of the Midwest moving along the stalled front in the northern Mid-Atlantic. Ozone production will thus be limited during the late week period.---McAuliffe
