Forecast Discussion: Times of clouds and sunshine this Wednesday afternoon. A weak cool front will bring a shower this afternoon and evening. Ozone levels will remain in the good range. High pressure will bring dry weather Thursday into Friday with sunshine and some clouds. Ozone concentrations will again be limited to the good range. A wave of low pressure passing well to our south Friday night into the Fourth will bring a good deal of clouds, and with an easterly flow, cleaner air will also move into the area. A shower is possible, but most of the time will be dry. As high pressure rebuilds Sunday into early next week, winds will shift into the southwest with more sunshine and warmer air. This might then act to push ozone levels up, possibly at moderate levels.---McAuliffe
