General themes: I matched each three month period starting Feb-Apr to various years in the past to build my analogs, and then rolled the blend forward. I built those analogs with El Nino following La Nina, -PDO, -QBO, volcanic, high solar years in the abstract. I have this as a 28.0C (+1.5C ish) El Nino in winter.

Just curious to see what the distribution is. Seems like most posters are on board with a strong or super nino, but I’m curious to see if a consensus is beginning to form or it’s still an even split. I’m going to start by putting in my vote for super (I’m thinking a peak of 2.3 or so).  ..read more
