2009-10 of course is going to end up being at least "an" analog with solar. ENSO will probably be similar although doubt we get a moderate Nino like that winter. Summer so far 500mb is polar opposite of 2009.
2014-15 could be another possible analog simply because this just has the feel of strong west coast ridging (PDO is going to spike, signs there already) & tendency for +NAO leaves a very cold source region over east Canada & Hudson Bay.
Low solar will more than likely enhance high latitude blocking, most likely in the EPO region or at least currently has that feel. I will say this, still coming out of a Nina background state, I'm not sold on super +NAO continuing just yet. I think NE ends up colder with +NAO with this setup versus having a -NAO. Of course, not exactly what you want to hear as far as big noreasters, however, all its takes is a transient -NAO block to work magic.
From my standpoint smart money overall at this point is a colder than average NE. AND REMEMBER, these are very preliminary thoughts. Lots can change depending on ENSO..etc.
