Forecast Discussion: Low pressure passing close by Thursday means showers and a thunderstorm for the area. Ozone levels will thus be limited to the good range. More clouds than sunshine on Friday with a shower or two still possible. Ozone levels should remain on the low side. Low ozone concentrations will then continue over the weekend with high pressure building southwestward into Pennsylvania.
