Hmm, seems as the AMO in its negative phase will have more of an impact on the eastern U.S. and especially Western Europe. Also it will be interesting to see the interaction between a positive PDO (that we have now). However, the PDO too is supposed to go back to a negative phase in a couple of years at most

Drought over north America has been correlated to the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation. The correlations account for the drought in the Great Plains during the 1930s dust bowl and more recent droughts.

Just precip data above but if you look at the years when we had a negative AMO and negative PDO we had cooler summers and cold winters (1960's and early 70's). Even when we had a negative AMO and positive PDO, in the late 70's and 80's our winters were cold here, but we had some scorching summers in the 1980's too.
Western Europe will see more low pressure systems and cooler summers with a negative AMO. Poisitve AMO's produce the opposite (more frequent heat).
