Although it's not as fast as just looking outside the window, WeatherBar adds an icon to your Windows 7 taskbar that will keep you on top of current weather conditions. This simple app installs a weather monitor on your Windows taskbar that changes the icon depending on the predicted weather. The progress meter indicates the relative humidity, and the jump list offers a full four-day prediction including highs, lows, and a predictive icon.
WeatherBar offers a standard program window, too. Along with a large version of the four-day predictions, you can enter in a city name or area code, choose either metric or English units, or change the update interval to as often as every minute. The benefit of this lightweight app is that, unlike a desktop widget, your weather prediction lives right in full view. If you're a weather junkie and using Windows 7, it might just be the unobtrusive weather app you need.
