Rio Grande flow dropped this week through Albuquerque, at a time when we should expect it to be rising with the accelerating melt of an unusually large snowmelt. What’s up with that? The answer (see below, I’m can’t figure out how to tl;dr this) is a case study in the stuff we’re trying to explain …
