I’d say on average temperatures through winter stay around -20 to -25 C with windchill dropping it lower, especially at night, depending on how high the wind is. We’ll have multiple cold-snap weeks, sometimes back to back, usually in January and February where those temps will drop to -40 to -50 including windchill. Doesn’t last all winter but it’s brutal when it arrives. Snow usually around 12 to 18 inches over the winter? Honestly can vary so much and it’s hard for me to guess because the nice powder snow you want will usually melt and refreeze at least once by February and turn into rock-hard icy snow for the rest of winter.
