Forecast Discussion: Current conditions: At 2 p.m. EST this Monday afternoon, northeasterly winds are circulating around an area of low pressure in eastern North Carolina. Rain is still falling across the area, and the rain in addition to strong mixing has led to low levels of fine particulate. Rain will taper to rain and snow showers overnight as the low starts to move off of the Delmarva peninsula, but little to no snow accumulation is expected. Low temperatures will fall to the lower to middle 30s. *** Tuesday's forecast: Mostly cloudy and breezy for Tuesday with a rain shower or two. Good low level mixing and ventilation will promote good air quality. Afternoon temperatures will recover to the middle 40s. Rather cloudy and not so cold Tuesday night with low temperatures in the middle 30s. *** Extended forecast: After a mild day on Wednesday, the weather pattern will revert to a more January-like regime by the end of this week as a broad based trough of low pressure digs across the northeastern U.S. A weak area of high pressure will bring clouds and perhaps some sunshine Wednesday with temperatures in the middle 50s. Enough of a breeze will be present to keep fine particulate in the good range. A cold front comes through early on Thursday, and brings a couple of rain and even snow showers. Turning colder with temperatures falling into the 30s Thursday. More clouds than sunshine with a cold wind Friday into Saturday with snow showers from time to time, with the heaviest activity across the mountains to the east. High temperatures will reach only the lower to middle 30s each day. Brisk northwesterly winds will keep fine particulate in the good range.---McAuliffe
