Forecast Discussion: Increasing clouds and thunderstorm activity Wednesday out ahead of a cold front. Thunderstorms are most likely in the afternoon hours. The clouds and rain will lower ozone concentrations to the upper good range. A cooler and less humid air mass will then follow on Thursday into Friday with ozone levels continuing to be in the good range. More moderate ozone might return to the area over the weekend with higher temperatures, a fair amount of sunshine, and higher humidity.
