How does DC get up to 104 in a developing Super El Nino? -pdo. Or at least something associated with it. I've seen enough data-correlation to make that connection.
Yup. I'd be curious to see in years where we have +QBO and strong +ENSO which factor ultimately has a stronger influence on the polar vortex and what those years tended to turn out like. Hopefully the fact that this year will be possibly a historically strong El Nino will help counter the +QBO a bit better than it might otherwise. Of course, SSWs are only half the equation and we have seen years where those effects don't always translate to favorable blocking in the troposphere.
So, as always, who knows except mother nature herself.
