With the weather delivered straight into the app you view the most (or for me at least) iCAL!!!
or any other calender app that can support ical subscriptions!
I get the subscriptions from the weather underground and they auto update every hour.
For e.g
Go to http://www.wunderground.com/global/stations/48698.html
Copy the link of the ical icon on the right hand side of the screen
and subscribe to it in iCal!
Thats it!
