I did a similar thing a while ago in bourne shell. It's fragile, as shell scripts should be, and shouldn't be relied upon. But it's a nice example of another way to do this. It was never written for public use, but what the hell. It uses Weather Underground, which means it has hourly info, and lots of other forecast stuff that the script is just ignoring for now. It also loads the json with the weather data without needing an API key, because that shit is for chumps. Oh, and its output is far, far more basic than Markus'. Attached.
