Author here -- Apple was definitely inspired by Dark Sky but IMO it's hard to argue that it's a replacement.

If you compare the # of clicks it takes and the amount of time it takes to interpret information for the same task for Dark Sky vs the Apple Weather app, it becomes clear that the Apple Weather app "isn't quite there yet". But I hope it will be soon!

If your needs are straightforward, then the Weather app is a pretty good replacement.
