Forecast Discussion: Current conditions: At 2 p.m. EDT this Monday afternoon, an area of low pressure centered over southwestern Pennsylvania was causing thunderstorms to develop across the state. This activity will affect parts of our area into this evening, with any heavier rain aggravating existing flooding. Patchy cloudiness later on overnight with areas of fog. *** Tuesday's forecast: Periods of clouds and sunshine for the day Tuesday as the upper level low slowly pulls off to the northeast. However, there can still be afternoon and evening thunderstorms pop up. Ozone levels will remain in the good range, as will fine particulate. *** Extended forecast: High pressure will return to the scene by the middle of the week with more in the way of sunshine Wednesday into Thursday. Ozone concentrations may rise to moderate levels Wednesday, with fine particulate also rising to the moderate range. Moderate air quality is likely with ozone and PM on Thursday as limited mixing will occur. A cold front then brings the chance for showers and thunderstorms back by the end of the week with air quality in the upper good/lower moderate range.---McAuliffe
