The monthly breakdown:
Used rough ENSO analogs (neutral ENSO to weak Nina summer going into weak/moderate Nina), coupled with NAO analogs based on low sun activity leading to -NAO in the winter. I also included -PDO to an extent, put all the factors together and weighted accordingly. Not all analogs fit the NAO/PDO correlations, but still fit most of the requirements.

NOTE: Anomalies are against 1971-2000 normals.
