I think your post over there in his thread was dead-on for Chicago, it's a 50-50 dice toss going forward after such a snowy pre-season. My gut tells me that while ENSO/SST/Oscillations are indeed less than stellar verbatim, some items he mentions may indeed come through in the end. One of significance being the MJO. Notably here, 4 of the last 7 Novembers have had BIG snow totals against my 1.2" long-term avg. Sometimes in one huge storm, other times in multiple lesser events. During that same 7 years, 3 Dec's have been complete "no shows", but I've also scored 3 huge Dec's with 2019 looming as the "tie breaker" thus a microcosm of your analog list for Chi-town snowy winters. I won't say this December will make or break the entire winter, but it could go a long ways toward helping this winter stand out from the crowd.
