The BBC weather service isn't very good any more, they switched from
https://www.metoffice.gov.uk/ to the rather rubbish MeteoGroup to save money when the licence fee was frozen.
For a text-based weather service see
http://www.wttr.in/
It's not as good as the Met Office forecast but it can be viewed in a terminal or from the TTY:
Not sure if that works with
ftp(1).
