Has EU weather sources per credits (DWD, ECMWF, EUMETSAT -- roughly what it's doing is graphing multiple models), but if you are into weather apps you're likely best off with Carrot that (a) lets you design your own UI including matching this (more or less), and (b) lets you choose among weather sources and flip among them with a tap.

If it's about cute UI and key notifications, try Hello Weather. For microcell notifications on anything, Tomorrow weather. For much better maps, WeatherMap.

For comparing multiple models, try Windy.app. For coastal barrier island use, I have 8 graphed at once, most of them EU models.

Very little reason for any weather app beyond Carrot, though Apple Weather is surprising evolved from the app of 20 years ago, no longer the 4th app to replace after messaging, maps, and browser).

Carrot is the only weather app with a vicious weather control AI singing an entire Broadway concept album about your destruction at you though.
