Forecast Discussion: Current conditions: At 2 p.m. EDT this Monday afternoon, a line of thunderstorms was developing in northwestern Pennsylvania and slipping to the south ahead of a cold front moving southward from New York state. A couple of these storms will cross the area this evening. *** Tuesday's forecast: A bit cooler Tuesday with a cloudy to partly sunny sky, and a shower or thunderstorm cannot be ruled out. A northerly flow of cleaner air will lower both ozone and fine particulate to the good range. *** Extended forecast: Low pressure coming out of the Ohio valley will bring more numerous showers and thunderstorms to the area Wednesday. Heavier bouts of rain and the cloud cover will keep ozone and fine particulate in the good range. High pressure will bring a nice day with lower humidity and a partly sunny sky for Thursday, then clouds will increase out ahead of the next system Friday. Ozone and fine particulate will remain down in the upper good to lower moderate range late this week.---McAuliffe
