A La Niña is looking more and more likely by the day. I think one of the keys will be what the QBO does in the fall, if it goes positive/westerly then it may be time to worry, especially if the -PDO, -AMO continues. As far as the solar cycle I’m not so sure it correlates to winter as well as some people had thought, same story with Siberian snowcover/SAI, just look at last winter....
