Forecast Discussion: Very dry air will continue across the area Friday with plenty of sunshine. Ozone might increase a little, but should remain in the good range. Ozone concentrations increase further on Saturday, but will continue to average in the good range. By the latter part of the Labor Day weekend, ozone levels will be restricted as to how high they can get due to increasing cloudiness and chances for afternoon convection.
