Since this part wasn't answered in a ton of detail, I'll give more info. No it's not below 0 F all winter - not really even close. It can go for a few days at a time without going above 0, but that's fairly rare.
The average high for every month is above zero; the average low is below zero in only one month (January). Not totally sure how much significance the mean temperature has, but the mean temp is below freezing November through March, and from April through October actually is 40+.
But in general, as to when it gets really cold, I'd say sometime mid-to-late November is when you really start to notice the cold, but only December, January, and February I'd call "really cold." There can be cold snaps in October, November, March, and April too though
