Is there any weather website (must be a website, no app) that offers
- Has accurate weather information
- Minimal UI like Dark Sky - concise presentation, light, fast
- Lightweight - fast to load, no unnecessary baggage
- No BS - weather, just weather, nothing else
Honorable mentions, but they have their problems
- windy.com - not lightweight
- wttr.in - may be great for terminal, not so much for browser
The National Weather Service is pretty good; their web presence has been exemplary since it began.
The recent switch to fancier presentation of radar data makes that mostly inaccessible to me, (satellite internet), but they still offer low bandwidth GIFs and are usable if you're willing to dig out the URLs. ex: https://radar.weather.gov/ridge/lite/KPAH_0.gif
