It only looks hot
Summertime, and the living is generally on the warm side. That's pretty much a given, particularly in my neck of the woods. I'd be suspicious, though, were someone to try to make me think it was hotter than it really is.
Recently I had some of my readers comment that they thought that The Weather Channel and USA Today (which uses TWC graphics) temperature maps seemed to look "hotter". They suspected that the colors had changed. I tend to watch such things since my own company (IntelliWeather) produces similar maps.
Which calls for a comparison test:
I decided that it would be an interesting exercise to compare USA national temperature maps from the commonly used services today. I saved national CURRENT temperature isotherms/gradient maps from around 03Z (11PM Eastern Time) [Thursday]. All were generated within about an hour of each other.
By convention, "red" and "hot" go together; you see red, you think it's at least kinda warm. The NOAA/NWS map legend doesn't call for red until it's downright pavement-melting hot: you have to get into the 90s just to rate a faint orange, and a true red demands triple digits. The Weather Channel doesn't publish its actual scale, but things start to redden around 70 in their world. And Accu-Weather thinks things are orange-worthy down in the 60s. (The link above has screens from all these, and others.)
Assuming skullduggery from this may be a stretch, but there's precedent.
