If you prefer your weather info in text and ASCII-art form, this is the command for you:

curl -4 http://wttr.in/New_York

Not only does the website display weather information purely with text and ASCII-art, it also looks identical when pulling it in with curl if you are so inclined.

The location is optional. It will do its best to guess where you are if you omit it.
