Windows 7: Like to keep the eye on the weather but never been too keen on sidebar gadgets or system tray apps? WeatherBar is a simple app that puts the weather in your Windows 7 taskbar, offering quick access to the forecast.
It actually is just a simple application. If you minimise it, hovering over its taskbar icon will show you the four-day forecast (which would work even better if you enlarged your Windows 7 thumbnail previews); right-clicking the app icon brings up a jumplist that displays a simplified version of the forecast. The app icon itself even offers information — the icon changes based on the weather and a progress indicator fills up based on relative humidity.
It's kind of a niche app, but if you're the type who likes to keep a constant eye on the weather, it's a fun idea.
