I have definitely noticed a tendency for the Pacific or GOA pattern in late November to often end up carrying through the winter.  I had never checked the stats on it but it seems more frequently it translates to Dec-Feb whereas the NAO in late November can mean nothing at all.  Obviously 2 notable cases that failed though were 89-90 and 93-94.  89 was about as perfect as it could get and went to hell after December.  1993 is the only case I recall where the AK vortex was a mainstay from late Nov into mid December and then retrograded and never came back the rest of the winter.  I had written off that winter by 12/15 based on that pattern and even CPC which back in those days tended to do much more scientific winters forecast a very mild winter for 93-94.
