Forecast Discussion: Ozone reached high moderate values for the 8-hour average yesterday, while PM2.5 also reached moderate levels. . A very weak cold front moves south of Indy Saturday afternoon, and may produce some clouds. However, this will be enough to increase the humidity tomorrow for Indy, which should be enough to limit ozone production. The front stalls overnight south of Indy, and keeps Louisville and Evansville in play for high ozone production tomorrow. Dew points and humidity are bit higher tomorrow in Evansville than in Louisville. The front shifts back to the north on Sunday as a warm front, and brings with it an increase in humidity and clouds, which will limit the pollutant production for Sunday. By Monday, a stronger cold front moves through the state, providing a chance for rain and thunderstorms throughout the day.
