I remember about 8 years ago there was an "experimental" site for one of the US government's aviation weather products. And it was so very good, designed modern and usable and clean. Didn't look at all like the usual awkward government website. The team seemed like nice folks too but were caught up in some multi-year government funding system. It eventually got shut down and IIRC, none of their work ever got promoted to the main site.
We are very lucky in the US to have a fantastic weather service and a mandate for their products to be free and public domain. Unfortunately there's also a lot of political pressure on them to not be too good so that some commercial company can profit. AccuWeather was one such company, at least back in 2005: https://www.onthecommons.org/privatizing-weather/index.html
