Forecast Discussion: Periods of clouds and sunshine this Thursday afternoon, with dry air coming in from the north keeping ozone levels in the upper good range. With a small area of high pressure centered north of us, Friday will turn out cloudy to partly sunny and on the dry side. Ozone levels should continue to not be a factor. More cloudiness from a wave of low pressure tracking through the Mid-Atlantic states on Saturday will mean ozone concentrations remain low. Ozone levels will be on the increase by the early part of next week as winds shift into the southwest, and bring in warm air and high humidity. Moderate readings are possible as temperatures rise into the lower to middle 80s.---McAuliffe
