It is very, very early, but those early signs show the potential for a major pattern shift sometime around January 15th. This could lead to cold, snow, and ice around the middle to late January.
Both the AO (Arctic Oscillation) and NAO (North Atlantic Oscillation) are expected to flip from positive to negative phase. This will allow the polar jet stream to dive south into the middle of the country it will also create a trough over the eastern part of the country. This is a much more favorable pattern for winter weather and being in a La Nina pattern, over running and the potential for ice will have to be watched as well. Again it is very early, but for all of the winter lover fans, there are some signs of change in the new year.
