Above, we see the 96 hour 500mb forecast from the Ocean Prediction Center, for the North Pacific. There are three storm systems here, all very strong as seen above. They are all going to be in the Bering Sea beginning on December 11, so we'll use that day as the starting date.
Many of you have heard of me mentioning something called the Bering Sea Rule (see the AccuWeather Forums for more info). How it works is, let's say a strong storm system appears in the Bering Sea. Research has shown that there is a 2.5-3 day gap (18-21 days) between a strong storm system in the Bering Sea, and a storm system in the Lower 48.
If we take that day of December 11, and take it out 18-21 days, we find ourselves between the days of December 29 and January 1- the days in the immediate vicinity of New Year's Day. If it takes these three systems a bit more time to move into the Bering Sea, we could see New Year's Day in the middle of this timeframe.
Just imagine what three storm systems in the Bering Sea could correlate to. I'm typing this, imaging what power could emerge if three storms were to merge into an extreme storm system in the Bering Sea. Only time could tell what such an event would mean for the Lower 48.
