Forecast Discussion: With sunshine and some clouds with very warm conditions this Thursday afternoon, ozone levels are climbing, and some may reach low moderate prior to thunderstorm activity late this afternoon into this evening. A cleaner air mass than recent days will arrive Friday on northeast winds with ozone improving into the good range. A couple of showers will also occur. Dry and pleasant weather conditions should prevail for the remainder of the Labor Day weekend, with air quality slightly deteriorating early next week.---McAuliffe
