Setting up wego on a raspbian were a bit painful (go in aptitude is 1.3 while wego requires 1.5), the easiest way that works out of the box is simply running curl wttr.in/Localtion ;)
But not as native ANSI though? Unless it's doing some clever useragent detection? (I'm on Windows without curl/wget).
Dunno, tried it on OS X and it's colorful and looks good.
Yes, it does return ANSI when you curl/wget the address.
