There are a lot of weather apps available but nothing is as stunning as Yahoo Weather. I've tried a number of related apps but I would always go back to Yahoo because of the beautiful images. The app recently received an update with animated effects like fog, heat, lighting, frost, rain, and snow. All you need to do is look at the app and you'll immediately know the weather outside. No need to open the windows because you'll know what's going on outside just by looking at your screen.
