Forecast Discussion: Current conditions: High pressure located across the eastern Great Lakes has resulted in winds turning light and variable this Monday afternoon. While low level mixing has lessened, fine particulate levels remain low. Clouds will increase and thicken tonight, and a shower or two moves in overnight. *** Tuesday’s forecast: A slow moving warm front will creep through southwestern Pennsylvania during the day Tuesday, and showers and a thunderstorm are likely to occur as this does so. A southwesterly wind flow will cause relative humidity and fine particulate levels to increase, but overall daily averages remain in the good range due to the rainfall washout. *** Extended forecast: Breezy and on the mild side Wednesday with clouds and a little sun, and a shower or thunderstorm cannot be ruled out. A brisk west to northwest flow will keep fine particulate down in the good range. A strong cold front comes through early in the day Thursday with additional showers. Colder air will follow the front later Thursday into Friday, with snow showers even possible Friday morning. High pressure behind the system brings tranquil, but chilly air Friday night into Saturday. Air quality will continue to be in good range late this week.---McAuliffe
