One of the more popular weather apps on iOS, Weather HD, has finally come to Android. It provides all of the usual weather data you'd want -- current temperature / humidity / precipitation / wind, 7-day forecasts and a few other customizable odds and ends. What's nice about Weather HD is the interface. It's the simplicity of gray and white text on a nicely animated background image, which changes with the current weather conditions, that really helps set this apart from some of the cluttered and busy weather apps. Unfortunately, Weather HD doesn't include a widget, though we'd expect it to soon if they want to stay competitive with the other popular weather apps out there.
Weather HD is available in the Google Play Store at the link above. It'll set you back 99 cents, or is free with advertisements.
