Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, a warm front was moving across southwestern Pennsylvania. This front, followed by a cold front which will pass through the area Friday morning, will act to trigger thunderstorm activity tonight and Friday morning. Tonight will be rather cloudy with showers and stronger thunderstorms moving through. *** Friday's forecast: Showers and a thunderstorm early Friday with the passage of a cold front, then turning breezy and less humid by the afternoon with sunshine returning. Afternoon temperatures in the lower to middle 80s with strong mixing lowering fine particulate and ozone down to the good range. Friday night will be partly cloudy and comfortably cool. *** Extended forecast: Clouds and a little sun Saturday with a couple of showers in response to a weak area of low pressure moving through. Ozone and fine particulate remaining in the good range. High pressure moving across the area Sunday into Monday will bring dry weather with seasonably warm air. With winds lightening and mixing becoming less, fine particulate and ozone will move back to moderate levels by Monday. The next cold front will move through Tuesday night or early Wednesday.---McAuliffe
