To get the most extreme crazy awesome weather info, you guys should play with APRS.
APRS (Automatic Position Reporting System) is a technology that takes gps information, along with a whole bunch of other information (weather info, icon, messages,...) and transmits it over an AX.25 protocol (radio amateur version of the X.25 network protocol) which can be over radio, or the internet. The latter is very interesting, even for non-radio amateurs, as there is a very big network of servers all over the world where radio amateurs and official services broadcast their weather information, amongst other things. This is interesting because first of all, the clients aviable for this protocol are -VERY- advanced. They can download satelite imagery from the net, live weather radar overlays, weather warning zones can also be an additional layer, they can work with tigermaps or other detailed map data, etc etc,... the posibilities are endless, and most clients allow you to write your own plugins for them. Secondly, you have access to a very massive amount of observations from all around the world. I'm not gonna get into the details as they are a bit complex, but I searched togeather some screenshots from google for you guys.
