Running your own Wii Forecast Channel
The Wii Forecast Channel was a channel available to WiiConnect24 users. It launched in November of 2006 and closed in 2013.
With services like RiiConnect24 and WiiLink, you can revive this channel and use it just like before, but if you're a nerd like me and want to add your own locations, you'll need to do some hacking. Fortunately it's pretty easy so long as your a little tech savy.
