Yesterday (July 25, 2023) was the hottest day in Albuquerque history

By one measure of overall heat, yesterday (July 25, 2023) was the hottest day ever recorded in Albuquerque. This is a tricky one, the sort of extreme I used to love back in my newspaper days when I needed a hook to slip stories like this past the filter of my editors. The daytime high …
