To put in perspective how freaky the 12z Euro would be, just look at this map of low pressure records for the month of June. Some of these records around the Lakes would be demolished.
The 3 Gulf coast systems that come to mind that had a big wind impact around the Lakes/OV are the 1900 Galveston hurricane, the 1941 hurricane and Ike from 2008. A couple others that backed in from the east coast and hammered the eastern sub would be Hazel and Sandy. All of these were September or October systems.
Several years ago I did extensive research on tropical remnant systems around the region and I cannot recall anything like what the Euro is advertising during a summer month. Maybe that would suggest leaning toward a tamer outcome at this distance.
