As the image above shows, there will be a rather deep area of negative height anomalies over East Asia for November 28th, as exhibited by the dark blues in the top left of the left-hand panel. There is a knwon correlation that indicates storm systems or ridges of high pressure over East Asia can be reciprocated in the United States 6-10 days after the event's occurrence in East Asia.

There are already a couple of guesses put out by the ECMWF control run. The most recent forecast has a storm system targeting the Midwest and Great Lakes for snow, as shown below (note the yellow arrow denoting the storm track)...
