The early Jan period has looked like our first best chance of timing something for some frozen for a while now. Several days ago it looked more like the 4th or 5th, now its a bit later. It is pretty much all we got other than hand wringing over the possibility of an awful pattern that may or may not verify going forward. That said, this modest threat still lies outside of 7 days and could easily evaporate or morph into something much different. As currently depicted by the major globals, it is about as good a look as we can expect given the general 500 mb pattern, and one that favors something tracking underneath with some decent cold air in place.
