N. Pacific pattern has been nothing like those years. July will be 6th straight month of -PNA. I know PDO is secondary to air, but it does run high correlation. Both 82-83 and 97-98 were big +PDO.
Have to think 1997-98 and 1982-83 are the best overall analogs, given ENSO strength and QBO. 2015-16 is also a good QBO match, but that was a second year Nino and this year looks much stronger.
I would put it on par with 2014-15 here. I don't think it will be much better this winter, but you never know. I believe 2023-24 was a pretty significant Nino and we had a great event in January and a bit onshore flow snow event at the end of February/beginning of March.
