Sure there's various ways to do this.
For example with:
http://weather.yahoo.com/
In my case, the place is Paris:
http://weather.yahoo.com/forecast/FRXX0076.html
I can use the RSS feed if I click on
:
http://xml.weather.yahoo.com/forecastrss?p=FRXX0076&u=f
Then I can use Feedbooks to create a newspaper with various blogs that I read, and use this feed to get weather forecasts in it. Check:

Or I could use it directly on my Kindle:
