Full width thumbnail

What about calling another content part above the sidebar and the post content block with a col-md-12 class. Call the Loop inside there with only the thumbnail and meta / any information you want there.

Then you call the rest of the post in the other content part which has a col-md-8 class and is positioned next to the sidebar.
