Actually, as Bastardi was pointing out in his Long Ranger the past few days, the big 1993 storm occurred with a sharply +AO and NAO. There was a huge upper low over Greenland and a trof that extended all the way across the pole, through Greenland to the western Caribbean - much like the models are predicting for about 10 days out. That storm dropped south out of western Canada, it didn't originate in the southern stream.
Sort of exciting to see the long-range models picking up on possible extreme cold or extreme snow. However, it would be more exciting if they could see a heat wave...
Did you see the latest Stratospheric data? Looks like another robust SSW event ahead as well. Good or bad timing, depending if you want to see colder weather.
