I live in northern Michigan. 25 F / -4 C is of course "cold", but it's not particularly problematic, you can under dress and it will be a fairly long time before you have problems. Down around 10 F / -12 C, you have to be a lot more aware.

And then if the regional/municipal governments have the equipment for it, a foot or two of snow a month really doesn't impact travel all that much (maybe for a few hours if there is a big storm).
