To be honest it wouldn't surprise me if both Autumn and winter were Atlantic dominated again, I still think our best chance of blocking will come towards the turn of the decade with low solar activity, surely we will get a combination of +ENSO, -QBO, minimum solar activity combination at some point, that said it wouldn't surprise me if we get a short late Autumn / Early winter period of blocking this year, its just very unlikely that everything will fall into place regarding very cold air being over the continent being drawn this way, its always a long shot, 1995, 2010, 1993 being examples though. its all about timing.
