The current design focuses on keeping the design clean and removing any information that is not required. The point of the radar page is that it is always up to date, and will let you know when the next image is arriving. The prediction page tells you when the rain is arriving.
I don’t have an Apple watch at the moment to test this on, but I’ll look into it when I can.
