Hold on to your butts, comrades. We're about to get a preview of 2050. I just checked the live data, and the area off the coast of South America that is the index water for ENSO is 9° F above average in places. This is going to be a wild year.
You've also got to look at precipitation and max temperature too, though. The USDA map really only takes the average extreme low temperature into account. That's changing, but it ain't the only thing.
