I don't think that I heard it as the coldest December since '60, but that is possible. I do know that our Christmas time cold broke some records though.

I was looking closely at my bill this afternoon (Columbia Gas of PA) and while it was indeed a colder December this year than last year which upped our usage a bit (keep the house at the same temps), the Supply charges doubled from last year to this year and the Delivery charges went up a decent amount as well. Those three factors are ultimately why folks are seeing significantly higher bills this December compared to last year. Mine personally jumped almost $150 from what it was at the same point in late 2021.
