June 20 2015 Storm Chase

Yesterday (June 20th), we were storm chasing eastern in Iowa. We saw a very well defined shelf cloud associated with a severe squall line which had horizontal rotation at Wayland, IA. This was from 7:00-7:05 PM CDT:

6 minutes later, and a little east of Wayland on highway 78:
A view from directly underneath the shelf cloud at the junction of 78 and US 218 at 7:14 PM:

While we were on our way home after the storm chase, we encountered a spectacular sunset near Muscatine, IA. We were able to see lightning from the storm to our east, a rainbow, crepuscular rays, and even anti-crepuscular rays. This was from 8:19-8:34 PM CDT.
