Forecast Discussion: At 2 p.m. EDT this Wednesday afternoon, a cold front was moving into western Pennsylvania. We will have showers and a thunderstorm with this front tonight as it passes. Thursday will start with clouds and a leftover shower, then some sunshine will appear in the afternoon. Cooler with highs in the middle 70s. High pressure controls the weather most of Friday into Saturday with more sunshine than clouds, and ozone levels will continue to be in the good range. We continue to watch the progress of Tropical Depression 9 as it moves out of the Gulf of Mexico into the southeastern U.S. over the next few days, and more clouds and even rain are possible Saturday night into Sunday if this tracks closer to us than forecast. Regardless, good air quality will continue through the weekend.---McAuliffe
