These regions are going to be the hardest hit this winter.I have discovered that a La Nina is a possible case through early January.Central/northern/northeast Illinois,northern/northwest indiana maybe central.The regions I just mentioned were mainly on the list because of one storm that looks to be on the 21-23 of December.I think this because at that time a positive PNA will be possible which was the key role in the Chicago blizzard.Another factor is a 50/50 chance of a La Nina which would help a lot.It is still far out  so it is hard to tell.The northeast is another region that will be affected be a major snowstorm.
