Forecast Discussion: High pressure to our northwest is building across Pennsylvania this Monday afternoon. Clear and cool tonight with temperatures falling to the middle and upper 50s. Sunshine for the most part on Tuesday with a pleasantly warm afternoon. Ozone levels will be higher than Monday, but still in the good range. More clouds move in for Wednesday with a thunderstorm also possible in the afternoon. These clouds will hamper ozone production, and keep concentrations in the good range. Cooler and drier air will sweep in later this week, with temperatures actually slightly below normal with good air quality.---McAuliffe
