Forecast Discussion: Current conditions: At 2 p.m. EDT this Wednesday afternoon, two areas of low pressure, one located over the Ohio valley, and the other across the Carolinas, were teaming up to bring significant rainfall to the area by tonight. The heaviest of this rain will come later on tonight into Thursday. While PM2.5 levels are elevated at the present time, a brisk east to southeast wind will mix most of this pollutant out of the atmosphere by later this afternoon. Therefore, most locations will end up in the upper good range overall today. Low pressure will bring in copious amounts of Atlantic moisture tonight, with heavier rain likely later on. *** Thursday's forecast: Overcast and cool for the day Thursday with rain, some of it heavy. Rain will begin to lighten some later in the afternoon as temperatures hold in the middle 60s. PM2.5 concentrations will be washed out to the good range with all of the rain and east-southeasterly winds. Rather cloudy Thursday night with a little rain and drizzle. *** Extended forecast: Unsettled weather will continue into the upcoming weekend as low pressure will be slow to move out. Continued rather cloudy on Friday with an east to northeasterly wind. Periods of rain and drizzle will still occur, and fine particulate will remain in the good range. Mostly cloudy and seasonably cool on Saturday with a couple of showers. Lighter winds and less rain may promote higher levels of PM2.5, but concentrations should remain inside the good range. The area of low pressure finally starts moving to the north and west of us by Sunday, and clouds may even break for a little sunshine. High pressure then rebuilds into the area early next week, keeping the weather dry with good air quality.---McAuliffe
