Divergence in models is apparent (as has already been mentioned and to be expected) once we get past the next 7 days.
However looking at the GFS ensemble and the extended ECM - the main message that seems to appear is a gradual transition away from blocked to a more progressive Atlantic type for the closing days of November and early December. This would imply wetter and milder conditions more likely to dominate. Towards mid-December the very latter stages of ECM would imply a return to blocked or more slowly progressive types. However If I take the current forecast position of the mid-December height recovery literally (always a very dangerous thing to do at that range) then it would imply dry, chilly and a potentially foggy set-up - without anything particularly notable in terms of extremity.
So insomuch as I can see - nothing to get overly excited about one way or the other - just at the moment.
