Nice job, Don.  So far in the first half of this November, the Scandinavian block has been a dominant 500mb feature.  This continues on models through November 26, making it a November leading anomaly. Since 1948, using both the + there, and - signal surrounding it, these are the top matches.  Rolled forward to December, it's a really nice -AAM signal, with the +/- balancing act in the Pacific vs Atlantic  January is blocking  Dec-Feb Temps
