This is momentarily interesting:
This map of the United States shows the range between the highest and lowest recorded extreme temperatures for each state. I think the most notable is that Alaska and California only differ by one degree. The state with the widest range, though, is Montana. Our New England states, which traditionally pride themselves on their tough winters and humid summers, are surprisingly middle-of-the-pack. Florida has the smallest range of the continental states, since, as you can tell from the data points, it is just basically fucking hot there all the time.
I’d love to see this broken down to a finer level of granularity so you could see the actual hot and cold spots in a given state.
