Forecast Discussion: Times of clouds and sunshine Wednesday with scattered thunderstorm activity developing in the afternoon. The thunderstorms and clouds should keep ozone down in the lower moderate range. Lower concentrations are likely on Thursday with a brisk northwesterly flow of drier air. Ozone levels might then make a comeback by Saturday as warmer and more humid air returns.
