This makes a lot of sense to me. I live in the Mojave Desert at about 3,000’ above sea level. The fall and spring transitions pose this exact risk. Today, for example, I’m looking at high of 80F but overnight we dropped to 39F and our humidity is hovering around 15%. Everyone jokes about it being a dry heat on those 120F days, but I’ll tell you what - dry cold is painfully colder than I could imagine and at much higher temperatures. Growing up in Massachusetts it was cold and humid and completely different. Here you can feel the heat pulling off you at 45F and it will feel sub-freezing. It’s weird to both need to keep water, so I don’t die of dehydration in heat, and a coat, so I don’t freeze to death, in the car at the same time. The desert doesn’t offer margin for error.
