You can get the data from several sources, but the NWS provides it in a GFW
format like on this page:

http://www.srh.noaa.gov/ridge/RadarImg/N0Z/

I have a blog entry about doing this, but it was written some time ago. It
is still valid, as far as I can tell, but some of the map data it points to
is missing. It also includes the script that generates the GEO file Scott
(N4CI) was using. It generates the GEO file from a GFW file downloaded from
noaa.gov.
