After umpty-ump years, the website of the Weather Channel has finally deprecated their "Classic Midwest Temperatures" map from which I've been autogenerating 6hr loops for...whoa, like 12 years.
I'm too lazy to think of anything better so I switched to the classic nationwide temperatures map for now, but I expect that'll disappear someday as well.
(Obviously this one won't animate until a few hours' worth of graphics have been grabbed.)
Now to figure out how to make money off these 102,566 loops...hello art project!
