Thanks for the comment. The NAO is much harder to forecast this far in advance as compared to things like ENSO. However, we know that the sign of the NAO can mean the prevalence of certain patterns across the United States. In fact, an earlier ENSO blog post talked about what the phases of NAO mean for the United States. I am sure forecasters will be looking at forecasts of the NAO as we get closer to winter to see what type of influence it may have.
