It definitely seems as if the GEFS has been flip flopping all over the place with the Pacific and the EPS has been more consistent with the December 13-20 period as Will and BrooklynWx said.  One worry as will said, the GEFS was the first to nail the Dec 6-10 period.  Considering EPS consistency recently you'd like to side with the EPS for the December 13-20 period..  Definitely a better vibe to the 00z runs than 12z yesterday, lets see if we can do it again at 12z today and get closer to next weekend with a good pattern to look forward to.  The good pattern is still kind of being pushed back to post day 10, I really want that to move up to day 7/8..  One small not technical thing I follow is all 3 ensembles were very snowy in the 10-15 day for the first time all year especially interior SNE on north..
