Forecast Discussion: Current Conditions: A weak area of high pressure is bringing in drier air to the region this Thursday afternoon. This influx of cleaner air is keeping ozone levels down in the upper good range. For the Day Friday, there will be periods of clouds and sunshine with the chance for afternoon and evening thunderstorm activity. Clouds and convection will thus keep ozone formation limited to the upper good range. A cold front approaching Saturday will bring an increased chance for showers and thunderstorms. Ozone will again be rather limited in how much can form. Turning cooler Sunday into Monday of next week with a good deal of cloud cover as well as the possibility of shower activity. Ozone will be very limited as a result of this changing weather pattern.---McAuliffe
