Forecast Discussion: Current conditions: Brisk easterly flow continues this Friday afternoon on the northern side of a stalled out front draped across the Mid-Atlantic. Fine particulate and ozone are still in the good range today across most of the area. Tonight will continue breezy with additional clouds and a shower or thundershower. *** Saturday's forecast: Clouds and only limited sunshine with a brisk south wind on Saturday, with a good chance for afternoon thunderstorms. Afternoon temperatures will rise into the middle and upper 70s, with fine particulate and ozone remaining in the good range. *** Sunday will turn out mostly cloudy with a shower or thundershower popping in the afternoon. Strong mixing will keep fine particulate and ozone down in the good range. *** Monday's forecast: Monday will start out dry, but then a couple of showers are possible later in the day as a weak area of low pressure comes in late in the day. *** Extended forecast: A cold front will continue the shower possibility Tuesday, then high pressure will finally dry things out by the mid week period with the return of more sunshine. Air quality will be mainly in the good range early next week.---McAuliffe
