Up that far north I would probably use a 70/30 mix of 70% Kentucky Blue grass with 30% creeping red fescue. They are finer bladed grass and make for very nice looking lawns. The fescue's are usually more drought tolerant and the tall fescue's have a wider blade generally. (like a Kentucky 31)
I would also add in a fair amount of annual rye grass seed that will die off but helps to prevent the rest of your seed from washing out and it germinates really fast.
Seeding rates:
Species in Seed Mix Rate (pounds/1,000 sq.ft.)
Kentucky bluegrass blend
1 to 3
Kentucky bluegrass/perennial ryegrass mix (80:20)
3 to 4
Kentucky bluegrass/fine fescue mix (50:50)
3 to 5
Tall fescue blend
6 to 9
I would go with the higher number if you have bare ground and it has been a while since the black dirt was applied.
Once seeded, and if you have access to one, roll it out to tamp down the seeds. You can probably rent one that you fill with the drum with water but if not, it isn't that big of a deal if you stay on top of it.
spread your seed evenly then I would cover with straw to prevent the rain from washing out the seed and to keep the direct sun off the new shoots.
Its not really too hard, just a bit of work but what better place to work than in ones own yard.
Good luck and hope that helps.
