Forecast Discussion: Current Conditions: At 2 p.m. EDT this Monday afternoon, high pressure is bringing a rather nice day to the region with a good deal of sunshine. Plenty of clean background air is promoting low concentrations of ozone and PM2.5. While PM2.5 values will increase some over the next couple of days, more clouds than sunshine will prevent ozone from going above the good range. Mainly moonlit and pleasant tonight with low temperatures in the lower 60s. *** Tuesday's forecast: A cold front will encroach on the area Tuesday, and bring increasing chances for showers and thunderstorms, mainly in the afternoon and evening. Plenty of clouds will keep ozone concentrations low, but high humidity and light winds will bring PM2.5 into the moderate range. Highs in the lower to middle 80s. Partly to mostly cloudy later Tuesday night with areas of fog. *** Extended forecast: More in the way of sunshine is expected for Wednesday, but enough moisture may linger for the chance of an afternoon or evening thunderstorm. Light winds will again promote moderate levels of fine particulate, while ozone remains in the good range. A series of weather systems then keeps shower chances high for the latter part of the week with little chance for elevated ozone, with upper good to low moderate levels of PM2.5.---McAuliffe
