Forecast Discussion: Current conditions: At 2 p.m. EDT this Tuesday afternoon, high pressure is keeping the weather dry and the air quality good. Later on this week, low pressure coming out of the Great Lakes will enhance the chances for rainfall. For tonight, we will have a clear to partly cloudy sky with low temperatures around the 50 degree mark. *** Wednesday's forecast: Clouds will limit sunshine on Wednesday as a low pressure strengthens and moves in our direction. Showers and a thunderstorm will also occur later on in the afternoon with temperatures near the 70 degree mark. Fine particulate will start the day moderate, with increasing mixing bringing good levels in the afternoon. Overcast Wednesday night with periods of rain occurring. *** Extended forecast: A broad area of low pressure across the eastern part of the nation will bring unsettled weather to the area Thursday into Friday with high probabilities of rain. With plenty of mixing and the occasional rainfall, fine particulate concentrations will remain low. Since the area of low pressure will be slow moving, chances for showers may continue over the weekend, with the next area of high pressure not building in until early next week.---McAuliffe
