FWIW this app used to be much more basic and worse before Apple bought a company (DarkSky) that was really good at making their own weather app and essentially incorporated DarkSky’s design into Weather. Which offers a little insight as to why their app is uniquely better - apparently building a great weather app is not as straightforward as one might think. In terms of really great well-designed apps that aren’t Apple’s the Norwegian meteorological agency maintains a really nice one called yr.no. It’s totally free (paid for by Norwegian taxes) and available worldwide. I use it in Scandinavia all the time, but less so in the States because like in your case the accuracy is diminished the further away you get from Norway. I bet it works pretty well in the UK though given the UK’s proximity to Norway.
