SterJo Weather Forecast is a simple free tool which can display a 5-day Yahoo!-powered weather forecast from your desktop.
Running the program adds an icon to your system tray, and hovering the mouse cursor over it gives you a basic weather summary: location, temperature, a few words on the current conditions.
Double-clicking the icon displays a window with the summary details, humidity, visibility, wind speed, sunrise and sunset times, and predictions for the next five days.
Right-clicking the system tray icons enables switching between landscape and portrait modes.
SterJo Weather Forecast tries to detect your location automatically. If this doesn't work or you'd like to use somewhere else, a Search box allows searching by city, region, post code and more. That's the theory, anyway-- in practice, the program failed to find any location, no matter what we entered.
SterJo Weather Forecast worked at a basic level for us, automatically detecting our current location and displaying weather data in a compact and visually appealing window.
We also had major problems, though, including a "Search Location" tool which never worked, and a desktop notification which appeared every time we minimise the program. Take a look if you like weather tools, but you'll be better off waiting for a few bug-fixing updates.
