I am way, WAY farther north than the OP, but getting similar weather. In fact our lows are only around -5 because the lake is close to my house and still un-frozen. But I've had a few days so far when I was snowblowing at 0 or less, and it sure is brisk when atomized snow gets in your face at those temperatures (no cab, and wouldn't want one 80% of the time). A nice full face balaclava and ski goggles worked pretty well though. This morning it was +5 when I cleared the latest 8" off the driveway.
We're on a typical to moderately heavy winter pace right now, and getting about 2 feet of powdery new snow each week. A small town 15 miles SW of me set an all time snow record (for the county) in December with 119" recorded by a trained observer. Six months ago I wasn't sure if I wanted or *needed* a snowblower, but I got one and it was totally worth it.
