Forecast Discussion: Current conditions: At 2 p.m. EDT this Tuesday afternoon, a cold front has moved off to the east of the area, and the humidity which has been a bother the past couple of days will lower considerably over the next 24 hours in the wake of this front. Tonight will turn out clear to partly cloudy and cooler as low temperatures fall back to the middle and upper 50s. *** Wednesday's forecast: Sunshine and a few clouds Wednesday with a pleasant, low humidity afternoon. A clean and dry north to northwesterly flow will bring ozone and fine particulate concentrations down inside the good range. *** Extended forecast: High pressure will continue to bring mostly sunny skies for the day Thursday, and with the still strong sun and light winds, ozone levels may rise into the lower moderate range. Low surface humidity will keep fine particulate down in the good range. Partly sunny skies for Friday with a warmer afternoon. A light south to southeast flow will mean ozone and fine particulate concentrations may rise to the moderate range. The weekend still looks unsettled with a slow moving area of low pressure coming out of the Midwest, and an increasing chance for showers and thunderstorms, especially late Saturday into Sunday. Conditions will not be favorable for ozone and PM2.5 buildups with plenty of cloud cover and precipitation during the weekend.---McAuliffe
