Data sparse area?

No not necessarily, it's more that those blocks are further south in the direct path of the PJ rather than the arctic blocks we see....so you end up with a lot of weird interactions with shortwaves that will change the orientation of the blocking....and since the blocking is a lot closer to us distance-wise, that orientation seems to affect our sensible wx more directly.

Eps has a nice look 

Terrible Pacific but a very good atlantic

The PAC isn't really bad in the 11-15 actually...trending better toward the end of that. It has PNA ridging with still signs of split flow....EPO is still pretty blah, but with the decent Atlantic, temps are plenty cold enough for threats.

Your area can benefit from an iffy  pacific and a good NAO.

If you want to see an example of how an ugly PAC with hudson bay and davis straight blocking can work out....the lead-in to the Dec 19-20, 1995 storm is a good example:
