Gary Lezak, the man who discovered the LRC, is indicating that an arctic blast of cold air is possible come mid January. We are investigating this, but at this time his confidence level seems fairly high. We are working to see if this may coincide with a possible break in the weather pattern.
The Ohio Valley southwest-ward into the Southern Plains will be experiencing wet conditions. Ohio has already broken all-time records for rainfall. This is expected to continue through the winter, and when the pattern change occurs, we will be seeing big snowstorms cut through the Ohio Valley. I am expecting several, if not many, 'major' snowstorms once the pattern changes for the Ohio Valley.
Down in the far Southern Plains we see an area of dry conditions expected. This is due to the La Nina, but has been helped by a +NAO/+AO.
Far out west, cooler than normal conditions are expected.
Notes about the indices:
-NAO should average above normal for the winter, but will dip negative at least once the rest of the winter. When it does dip into a good negative, I can see a big snow hit the Northeast.
-AO is in the same boat as the NAO.

Before you jump to the conclusion that this is Global Warming at its best, it's not. This is simply a weather pattern gone bad. The same bad weather pattern has delayed winter. And no, this bad pattern is not due to global warming.
