Pattern Altitude
Here's another cool aviation weather site: www.mymetar.com. You can specify lists of airports whose metars you can see at a glance, as well as weather mosaics that you want to see. The really cool thing is that they are really into making it available on mobile web-enabled devices, including special apps for you iPhone bandwagon jumper-oners . I like that it lets you create a RSS feed for your airport lists, so I have mine displayed right on my ATT/Yahoo! homepage. It's not the end-all and be-all of weather sites, but it's good to use with all of your other favorites, and as a disclaimer, this should not be used in lieu of an official FSS briefing. Enjoy!
