Radarmatic: a weather radar visualizer and API

Interesting, but it seems to duplicate Weather Underground's wundermap that's been available for a few years now: http://www.wunderground.com/wundermap/

Wundermap also displays data from personal weather stations, storm tracks, sattelite imagery, etc.

Ok, but inferior to weather.com. I don't care what radar the information is coming from, and I don't want to see ground clutter. Weather.com merges all sites, removes ground clutter, and adds satellite overlays. Also, when I see a loop, I usually want to see a longer timescale, like the last few hours, instead of a few minutes. Most people are interested in seeing a few hours because you can tell whether cells are building, what direction the cells are going, and what direction the system is going. This is all very hard to tell with individual sites and short timescales.

That's awesome, but it doesn't seem to work for me. Maybe it's just getting hit.. or it's the clearest day in recent history for the whole USA
