Forecast Discussion: Current Conditions: Fine particulate concentrations were again elevated early this morning, but some mixing has lowered values considerably this Friday afternoon. Winds have shifted into the southwest, and temperatures are rising close to 70 degrees with plenty of sunshine. With a temperature inversion developing overnight along with calm surface winds, fine particulate levels will go well into the moderate range. *** Saturday's forecast: Fine particulate will start the day elevated, then a little afternoon mixing along with the breaking inversion causes concentrations to drop. Once again, average concentrations for the day end up in the moderate range. *** Sunday's forecast: Sunshine and a few clouds Sunday with another mild afternoon as the mercury leaps into the middle 70s. With stronger mixing present, average concentrations of PM2.5 will be in the low moderate range. *** Monday's forecast: Sunshine will yield to clouds by late in the day Monday. A light to moderate south wind spells moderate air quality for the region. *** Extended forecast: A strong cold front will bring a good dose of rain, and even a thunderstorm to the area late Monday night into Tuesday. There will be a big change to colder and more seasonable weather by the middle of the week, as high temperatures remain in the lower to middle 50s Wednesday. Brisk mixing from the west and northwest brings good air quality during the mid week period.---McAuliffe
