Let me Introduce you eWether HD app, which is probably the best wether app & widget on the market. The developers just released the new version, but first take a look at the main features.
This is the first App in the world with a Hi-Def Radar Widget, Weather Map Widget and an Earthquakes Map Widget.
eWeather HD is the most informative Android application about your environment: Current weather and weather forecasts from different weather providers, NOAA weather alerts, latest earthquakes, live radar, geomagnetic storm forecast, pressure change indicator, wind and moon and sun calendar, METAR.
The NOAA Doppler Radar shows tornado, rain, snow, and hail clouds movement on Google Maps around your location in real time with higher resolution images than any other app for Android.
One of the new features that ships with Jelly Bean is Google's Sound Search widget that helps identify songs after listening to short samples. If you've ever used SoundHound or Shazam, you know exactly what this does. The difference is this widget is pre-installed on Jelly Bean, comes directly from Google, and hooks right into Google Play.
