After a lot of searching and trying out various weather apps, Partly Cloudy has been my favourite for several months now.
I just have an issue with part of the UI: where there is text on a black background, there is not enough contrast to comfortably read the text. This only affects the "Last Updated" info and the (optional in-app purchase) "black theme", so it doesnt affect everyday use, but it still would be good to have this fixed.
