Forecast Discussion: Current Conditions: At 2 p.m. EDT this Tuesday afternoon, low pressure located over eastern North Carolina was spinning rain in the direction of southeastern Pennsylvania, but across our area, rain has tapered off to showers. These showers will continue into this evening, then things will dry out and become warmer by Wednesday as low pressure pulls off to the northeast and weakens. Rather cloudy overnight with fine particulate rising some, but still remaining in the good range with areas of fog. The mercury will fall back into the lower 50s. *** Wednesday's forecast: Light south winds along with times of clouds and sunshine will promote a warmer day for Wednesday as temperatures climb close to 80 degrees. Fine particulate matter and even ozone may rise to moderate levels. Mostly clear and mild Wednesday night with lows only in the lower 60s. *** Extended forecast: Breezy and warm for Thursday with clouds mixing with sunshine. Brisk southwest winds will keep ozone and fine particulate elevated some, but levels could drop into the good range in the afternoon with significant mixing. A cold front can bring a shower or thunderstorm to the area Thursday night. Not as warm for Friday with periods of clouds and sunshine. Drier air will promote good air quality in most locations. A warm front on Saturday may bring showers or a thunderstorm with low levels of fine particulate. A stronger cold front may bring showers and thunderstorms late Monday into Monday night.---McAuliffe
