The article mentions the potential for a super El Nino at the very end but doesn't discuss the effect it could have on content in the map should it go down as modeled. I suspect that a lot of yellows and red will disappear or shift to the north.
I know that the last super El Nino in 2015-2016 followed similar drought conditions due to La Nina such that rainfall at my property, which is normally ~36" (91.4 cm) annually (that's a 20 year average taken here on my property) was below average for the period 2010-2014 by 3-5" (7.62-12.7 cm) and up to 10" (25.4 cm) in 2014. Once La Nina faded it began to rain in August and rained out through December and we ended the year with 68" (172.7 cm) rainfall. In the decades that I have lived here and tracked rainfall that is the wettest year by more than 14" (35.6 cm).
We are currently behind the curve here but I have faith in their predictions since it also comes with a promise of ridiculously hot temperatures to make the last months of the year humid well past normal. It has been cooler than normal so far and drier than normal (La Nina hanging on by a thread). The script will flip and N Texas will again be a miserable place to be if you work outside.
The areas of extreme drought may change each year, but the total area affected seems rather ordinary to me.
Agriculture and city replacing trees wiped out the Mayans: https://news.climate.columbia.edu/2012/08/20/forest-razing-b...
Tree loss being a 60% contributing factor to the Mayan case. When the Mayans ran out of water, their civilization collapsed, and their technology and advanced astronomical science faded from memory.
We are speed running toward the same peril in modern times.

> Who draws the map?
> Meteorologists and climatologists from the NDMC, NOAA and USDA take turns as the lead author of the map, usually two weeks a time. The author’s job is to do something that a computer can’t. When the data is pointing in different directions, they make sense out of it.
> How do we know when we're in a drought?
> No single piece of evidence tells the full story, and neither do strictly physical indicators. That’s why the USDM isn’t a statistical model
