Forecast Discussion: Current conditions: At 2 p.m. EDT this Friday afternoon, warmer air has moved into the region on brisk southwesterly winds. These winds have brought fine particulate levels down some this afternoon, but overall levels for the day will end up in the low moderate range. Rather cloudy overnight with areas of fog forming, and temperatures will not drop below the 50 degree mark. *** Saturday's forecast: Clouds for the most part Saturday with a very mild afternoon as temperatures climb close to 70 degrees in the afternoon. A shower or two can also occur in the afternoon. Winds and precipitation will be too light to bring fine particulate levels down below the moderate range. *** Sunday's forecast: An area of low pressure coming out of the Ohio valley will bring another round of showery weather to the region Sunday, and a thunderstorm cannot be ruled out with temperatures rising into the upper 60s. Stronger low level mixing and heavier precipitation may bring fine particulate down into the good range. *** Monday's forecast: Monday will bring variable cloudiness to the region with a shower or two still possible in a light southwesterly flow, and a little sun could also appear as temperatures remain on the mild side. Limited mixing again keeps PM2.5 levels in the moderate range. *** Tuesday's forecast: A cold front slated to come through on Tuesday may bring showers and a thunderstorm to the area, with fine particulate averages remaining moderate. Turning cooler with temperatures returning to normal by the middle of next week with air quality overall in the good range. ---McAuliffe
