How do you build a weather API?

Question

I'm sure a lot of HN'ers are sad to see Dark Sky go, so I was wondering what it would take to build something like it from scratch. On the off-chance that someone here has the expertise to explain, what goes into building a weather API like Dark Sky? At the very least, where does the raw data come from?

Well, this Internet Archive of Dark Sky's Kickstarter is probably a good reference :)https://web.archive.org/web/20200119040556/https://www.kicks...
