Welllllll, maybe, maybe not. No doubt the ridge in eastern Canada is the wild card, but there are ridges across the globe and there's no guarantee the one in se Canada will be too warm or that it won't be centered further north. And exactly how it morphs over the season will obviously have something to say about it, as I think we both agree it will become more forgiving after December. That said, I still don't hold much hope for December simply due to climo.
P.s Just so that you understand my pov, I don't care about monthly temps, only snowfall. And we can squeeze a storm out of a warm month.
