Forecast Discussion: Wed : Ozone was good yesterday, with PM2.5 readings being good in central Indiana with mixed moderate readings in Kentucky and southern Indiana. Morning fog persists again today especially after evening thundershowers. Humidity will only increase over the next few days as a ridge continues to build over the Mississippi Valley and eventually Tennessee Valley. Multiple rounds of strong to potentially severe convection is possible as shortwaves ride over the ridge and dive southeastward. A warm front will lift north in the next few days providing another trigger for convection.
