For future reference it's better to admit fault than delete posts, whatever the reason. It's human nature to be wrong sometimes, certain people in current times would like us to forget that, but I digress.
The blizzard you've mentioned is insanely unlikely, even in your own words, a 1 in 200 year storm. What you have right now is a hunch, but spreading information on a storm like that which could literally put lives in danger is alarmist and morally wrong. It's fun to day dream about systems like that in current times, but just don't post them. Until you have evidence, more than SSTs, I'd agree with
@Rain Cold with trying to approach it with more science. I don't think you're a troll, but there's a reason a lot of great meteorological minds aren't discussing a 1 in 200 year storm to end this likely record breaking HOT winter. In order to have a region wide system like that to dump feet, you would need deep cold, deep bone chilling cold. We'd be lucky to get sustained (more than 3 days) of climo normal temperatures at this point in this above normal winter.
These systems cannot be predicted without model guidance...they just can't. Remember, the large scale pattern supporting a large blizzard would likely show up before the actual system on NWP. That's what is so fun about pattern recognition...you get the ingredients of the main dish early, but there is no such pattern on any kind of seasonal or ensemble model. We know this to be 100% factual.
