Right now it is about -11 outside, which is about the average low for January and February. It's been above average most of the time recently. Like, the high today was 2, when the average high should be around -3 or so. That's pretty much winter.
Summer can average highs around 25 to 27 (generally, July). Every so often we'll hit something in the 30s. The low could be between 14 to 18.
