Forecast Discussion: A cold front is moving through central Pennsylvania this Tuesday afternoon. A thunderstorm will pop in parts of the area this afternoon. An adequate amount of mixing has limited ozone formation to the good range. The good air quality will continue through the midweek period with high pressure in control and a clean air mass that will contain limited ozone precursors. A wave of low pressure passes to our south Friday, and could bring a couple of showers. Ozone will thus be at a minimum. A new area of high pressure builds in from the Midwest over the weekend with ozone remaining in the upper good range.---McAuliffe
