The Northern Hemispheric pattern setting up is probably the best we've seen since 09/10 and 10/11(if you like snow in the east). Anytime you get such extreme blocking in the Atlantic (-NAO), the model trends are usually in favor of increased amplification and cutoffs upstream. Aka any fart in the wind can turn into a SECS. This pattern will likely produce, but I wouldn't get too caught up in the individual model solutions this far out.
