Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, a cold front was moving through central Ohio, with showers and thunderstorms developing near and out ahead of it. Some of this activity will work it's way into western Pennsylvania over the next few hours. Some of the storms may be on the strong side this evening as the cold front moves through. *** Friday's forecast: Clouds and a little sunshine for the day on Friday with a small area of high pressure overhead. Not as warm with temperatures in the lower to middle 70s, and with less mixing present, fine particulate levels will be moderate. Ozone concentrations will be more limited due to an increase in afternoon cloud cover. Rather cloudy Friday night with a couple of rain showers possible. *** Extended forecast: Periods of clouds and some sunshine Saturday, but a stationary frontal boundary will still be nearby and produce a shower or thundershower. Light recirculating flow may cause PM2.5 levels to be moderate once more. Times of clouds and sunshine, warm, and humid for Sunday with a thundershower still possible, mainly in the afternoon. With temperatures moving into the lower 80s, fine particulate and ozone may rise to moderate levels. A cold front then approaches from the west on Monday and brings a good chance for showers and thunderstorms. A return to cooler weather and good air quality behind the front Tuesday and Wednesday.---McAuliffe
