I have moved from Dark Sky to Weather Strip: https://www.weatherstrip.app

It does a really nice job of showing me most of what Dark Sky showed, in a similarly easy-to-glance-at format once I spent a little time learning to read its graphs.

I think Carrot Weather has a lot of graphs directly ripped off from Dark Sky but the constant attempts to upsell me to a subscription plan while I was playing with it really turned me off, as did the "what political alignment would you like the sweary forecast to have" switch.
