Forecast Discussion: Current conditions: The clockwise circulation around an area of high pressure over the eastern Great Lakes has created a north to northwesterly flow of clean and dry air for central Pennsylvania this Monday afternoon. Fine particulate levels are well down inside the good range with this air mass. Moonlight early tonight will yield to cloudiness later on overnight. *** Tuesday’s forecast: A slow moving warm front will creep into the area from the southwest late in the day Tuesday. The sky will turn out mostly cloudy out ahead of it with showers likely in the afternoon and at night. Less mixing will lead to an increase in fine particulate concentrations, perhaps into the upper good range across parts of the area. *** Extended forecast: Showers will linger into Wednesday, but increasing low level mixing should permit PM2.5 levels to drop back into the good range. A strong cold front then moves through on Thursday with a continued chance for showers, along with a gusty wind. Chilly air will prevail in the wake of the front in the form of a brisk northwest flow Friday into Saturday. Air quality will remain good Thursday into Saturday.---McAuliffe
