I was headed to the Baskin-Dunkin in Vernon Hills to meet some friends when I caught sight of a nice storm with a lot of lighting. The storm was t-storm warned as it slowly crossed into IL from WI. The storm was headed east towards the lake, but slowly sank south towards the Chicagoland area throughout the rest of the night.
The only CG I saw that night (1:32AM to be exact), in Vernon Hills, IL
