If you're interested in global weather patterns, then there's a FTP URL for you. ftp://cumulus.met.ed.ac.uk/.
keeps global weather animations of the last 24 hours and the last week, as well as the latest images from weather satellites. The animations are in popular formats such as MPEG, so they can be played under all PC and Mac platforms with the appropriate software (check the SEDS ftp site if you need to find this software).
If you like to keep up on all the latest and greatest images from the Hubble Space Telescope, look no further than http://marvel.stsci.edu/EPA/Recent.html (Check out the latest Mars movie!!--it's also on SEDS ftp in the incoming directory).

Don't waste your money on music mags like Rolling Stone or Spin; http://www.addict.com/ATN/ is Addicted To Noise, and has all you need.
Also, there isn't much need to subscribe to a weekly news magazine or newspaper when you've got http://www.sjmercury.com/ or http://www.trib.com/news/news.html with the latest news and photos from the major news services. Time magazine has a somewhat more succinct daily presentation at http://www.timeinc.com/time/ timehomepage.html .
Of course, the U of A Daily Wildcat is also on the web, but somehow reading it on-line is not as satisfying (perhaps because you can't throw it in the trash!).
The Tucson Movie Guide (http://188.8.131.52/tmg/) presents a complete hypertext guide to local shows.
In-depth political commentary can be found with Mother Jones at http://www.mojones.com/mojo_magazine.html.
