These are great! I've been looking for something like this for a long time and I could never find anything out of NOAA that had this kind of time resolution. Here about a big storm on the east coast? What does it look like from space? Gotta wait to see whether someone will do a press release.
You might find http://realearth.ssec.wisc.edu/ useful. Just be sure to click on either the "Presets" or "All" tabs within the "Layers" section.
Oh, and if you decide to use the animation feature just try to be patient with the way it loads in the individual times--once you've pulled down everything the animation should look a good bit nicer.
