Geometric Weather is a fantastic app with the same look and feel. Carrot Weather also just (?) added what is effectively a "DarkSky mode". It's lovely.
Geometric Weather looks good, but I'm not crazy about its Accuweather backend.
One newish app that's good (though it unfortunately doesn't have a status bar weather indicator) is omWeather[1], and it uses Open-Meteo as its backend.
