Forecast Discussion: Current conditions: Skies are mostly cloudy with some sunny breaks this Friday afternoon as high pressure builds in from the Ohio valley. In spite of winds decreasing considerably over Thursday, fine particulate remains in the good range. Increases in particles are likely over the weekend with continued light surface winds and the lack of mixing as high pressure remains in control. Mostly clear overnight with an inversion developing later on as winds go to calm. *** Saturday's forecast: Sunshine and some mid and high clouds Saturday with a nice afternoon as temperatures recover to the lower 60s. Fine particulate levels will be on the rise, moving into the lower moderate range. *** Sunday's forecast: Another day of light winds and a morning inversion Sunday will send fine particulate into the moderate range, with periods of clouds and sunshine and a nice afternoon. *** Monday's forecast: Tranquil weather will start off the new work week with light winds and another morning inversion bringing moderate air quality. Afternoon temperatures will rise into the lower 70s. *** Extended forecast: The next cold front brings a round of rain with it Tuesday, then a new area of high pressure brings dry weather back for the mid week period. Air quality will be in the good range Tuesday into Wednesday.---McAuliffe
