If you like to stay up-to-date with the weather, then WeatherBar is one taskbar widget you want to check out!
WeatherBar is an application written in C# to show the weather in a specific location.
One point that makes this application different from other weather applications and gadgets is the ability to integrate with the Windows 7 taskbar.
Therefore, instead of constantly switching to the desktop to take a peek at the pinned gadget, the user can simply take a look at the taskbar, or right-click on the taskbar application icon to read the forecast.
