A consumer-friendly front end to NOAA/NWS website, and adequate documentation for their APIs would be a nice start. Weather.com, accuweather and wunderground exist, but they're all buggy and choked with ads. If I want to track daily rainfall in my area vs local water reservoir levels vs local water table readings, I can do that, all the information exists but I can't conveniently link it together. The fed has a great website where you can build all sorts of tables and graphs about current and historical economic market data, but environmental/weather data is left out in the cold right now.
