That looks like you have a Green Ash there (
Fraxinus pennsylvanica), though some clearer pictures of branches and pinnate compound leaf attachment thereto would help clarify the ID.
I suspect some Ash anthracnose is in play here, too, given your statement about "...a ton of rain..."
Are you aware of reports or activity of Emerald Ash Borer (EAB) in the Minneapolis area? If your tree is under stress from that kind of infestation, your mitigation choices may be very different. It is NOT a friendly foe.
More info on EAB in MN can be found here...
