Oh man I miss Dark Sky. I have yet to find a weather app as good. briefsky[0] was recently posted on here and I think I'll try using it for a while. Also of note is Pirate Weather[1], a weather API in the same style as Dark Sky.
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.
Merry Sky (https://merrysky.net/) has replaced Dark Sky for me, a homescreen link to the website and it's doing a good job for at a glance weather and 'feels like' lookups.
