Forecast Discussion: Current Conditions: High pressure has built over the area this Friday afternoon, with much less wind than earlier. With the aid of a little sunshine, temperatures are moving into the middle 40s. Very dry air at present has also kept fine particulate well down in the good range. Tonight, clouds will thicken out ahead of an approaching warm front, and rain from this is likely before morning. *** Saturday's forecast: Rather cloudy and turning milder Saturday with a couple of showers and a thunderstorm. Temperatures rising into the middle 50s with enough mixing to keep PM2.5 levels in the good range once again. A strong cold front cuts through the region Saturday night with rain and a thunderstorm likely. Rain will taper to rain showers later Saturday night as it turns windy and colder with temperatures falling back to the middle 30s. *** Sunday's forecast: Windy and cold Sunday with rain and snow showers, and the strong and gusty winds will send fine particulate down to very low levels. Temperatures will hold in the upper 30s. Additional snow showers are likely Sunday night, but with little or no accumulation. *** Monday's forecast: High pressure will build over the Mid-Atlantic states Monday, and brisk winds will maintain good air quality. With more sunshine, temperatures will recover to the lower to middle 40s. *** Extended forecast: Winds will turn into the southwest Tuesday with partly to mostly sunny skies and a milder afternoon. While fine particulate will rise some, it should remain at the high end of the good range. The next cold front then comes through Tuesday evening, followed by another influx of cold air Wednesday into Thanksgiving Day along with good air quality.---McAuliffe
