A solid 5w30, 5w20 or 0w20 would be just fine. In your area where it does routinely get to -10°F to -15°F these all would make it just fine in those temps. If I was looking at a particular brand I would go with Mobil EP 0w20, Castrol Magnatec 0w20, Castrol Magnatec 5w30.
Guess what I saw at a Napa near me Captain?? Amsoil Signature Series 5w30, 0w30, 5w20. Surprised me a good bit. That Napa in Smithfield, Va had a very good oil selection across the board. I was impressed. I told the guys there that the Napa near me was trailer park in comparison to their good/nice store.
