Blocking would be lovely, but as we all know, its pretty rare during winter lately. We could see something transient ofc, but if this winter is to feature a colder period, I am inclined to think it will probably require a favorable EPAC for a time, something like Jan of 2018. No one in DC area should expect more than a low end warning event or 2 at best, and hopefully a few 1-2" deals. That would be a major win after the debacle of last winter.
