Forecast Discussion: At 2 p.m. EDT this Thursday afternoon, a large area of low pressure is moving into Pennsylvania from the west. Showers and thunderstorms will be numerous this afternoon and tonight. With morning clouds slow to break Friday, along with scattered convection possible later on in the day, ozone levels should remain in the good range. Another round of cloudiness with showers and a thunderstorm is likely again later in the day Saturday, so ozone formation will again be limited.---McAuliffe
