The NAO and AO will be big players this winter. I think we might need them to go pretty negative to help get cold shots down here. The El Nino winter of 2009 had a major negative NAO and AO. One of the blockiest winters of all time. If we can just get the blocking to occur up North it could be a very good winter for snow lovers. I would imagine the jetstream will have a more favorable setup for big storms and bringing moisture up from the South. Cold air is my biggest concern right now.
