Forecast Discussion: Ozone and PM2.5 have been good. A wave will move to the southeast and kick off a few thundershowers. The Another cold front will push through tonight and into the Carolinas by Sunday morning. The big ridge over the Rockies will keep us in a northwesterly weather pattern for the weekend. Surface high will move off to the east and allow a cold front to move through part of Indiana on Monday, but the chances of storms will be less with lower humidites than what we’ve experienced lately.
