Looking at the overnighers, the 0z GFS surface maps look more reasonable as to potential evolution for the 12/22 event. As I stated previously, the lack of cold in the eastern NH, is really throwing a big wrench into what could be a formidable event. I'm not trying to be a debbie, and yes, due to climo, there could be some surprises, as the storm has the ability to bring down/manufacture some/enough cold for some surprises. Long n short, its just not that cold in eastern canada, and as depicted, we'd need that.
Again, I hope I'm wrong and look forward to all of you proving it.
Like bubbles suggests, that is the fun for many of us. Trying to figure this stuff out.
This one is rather telling IMO. Mind you its just a run, but sorta aligns w/ ens maps at 500mb, and thermally its just a hot enough mess.
