From Grain Edit:
David Elenga has created a simple yet elegant weather app called WTHR which is inspired by Dieter Rams’ Ten Principles of Design. At the top of the screen the current weather condition is displayed along with the temperature for your area. Just below is a 7-day forecast and a nifty switch which allows you to select between Fahrenheit or Celsius. Unfortunately version 1.0 has some bugs and usability issues which should hopefully be resolved soon. I would hold off on downloading the app until the release of version 1.1 which is slated for sometime next week.
