Anything's possible. It's just a matter of finding a nice source of that data. One of the wunderground meteorologists gave me some links for those other models, but they weren't in the same format as the ones I currently use. I need to spend a good day or 2 really cleaning up the code, and possibly adding some new stuff, but I've been working on a new pet project recently. The ones I have currently included are the official NHC ones that they make public via their FTP. I was surprised to see that getting access to some of this data was restricted and/or a pay service. I'll definitely look into the UKMET one in the next couple of days (probably not soon enough for katrina though) because even I am frustrated that it's not currently included. Just keep your fingers crossed that I can find the data in a reliable format.
