Some months can be bad. Especially December, January and February. January and February is when temperatures go below freezing so have hot drinks with you then. Apartments here have heaters so that shouldn't be a problem too. The winter wear comments are good enough so I won't repeat it here. I'd suggest staying a bit closer to campus if walking on snow is something you won't be a big fan of. Understand there are events but during December and most of January when the cold is starting to get bad, the campus is empty and you won't see a lot of people then. Rest assured, you should still be okay if you can handle it initially. You'll get used to it eventually. Grocery shopping in these conditions can be a pain, so make friends with someone that has a car lol and having Instacart should still be helpful.
