title: Weather API with date parameter
body: <p>I am looking for a weather api that I can query by latlng and date.  The date seems to be the hard part.  All the APIs seem to only return the weather at he current day and/or week.  I also need it to work worldwide and not just in the US.</p>
  
  <p>Can anybody suggest one?  Ideally i'd like to use Google or Yahoo but i don't think they provide this functionality or at least it is not documented</p>
