I was able to get some shelf cloud and lightning photos as a couple evening storms passed the Edwardsvile, IL area. The first picture was taken from a couple miles east of Edwardsville, looking northwest:

The following pictures of CC (cloud-to-cloud) lightning were taken from Glik Park in Edwardsville looking southeast:
