Thanks for the clarification.
Maybe I am wrong, but I did not see the issue, at least not predominately, as a 2001-2002 type relentless PAC firehose that eradicates N America of cold, last year. We had plenty of cold, but in the absence of a pos PDO, the cold dumped west, and with no Atl blocking, there was nothing to hold it and prevent storms from displacing it.
