In the 2012 WeatherDock will come back, supporting a new look and feel and using a new weather-information provider.
The main window and menu item both will have a interface overhaul. Also quite enhanced is the spoken weather report, now also available in localized versions of the application.
Dropping weather.com® in favor of Wunderground® brings up new information and new ways to display them.
Check out the WeatherDock 3 Preview page for more information.
