SharpWeather

SharpWeather is an application you can use to stay up to date with the latest weather conditions in any location. It's multilingual and enables you to specify the update frequency. Information is obtained from Weather.com.

Installation and interface

The setup operation doesn't take long. However, you must have .NET Framework installed, since it was built with the help of this platform. Although this isn't mentioned, the tool gets integrated into the Windows autostart sequence, but this can be later disabled from the settings panel.
It creates a systray icon that facilitates quick access to its configuration options. When it's not being used, it silently runs there while being minimally invasive to let you carry on with your normal PC activity without disturbances.

Configure settings to view weather details

It's possible to show the weather balloon on program startup, select the preferred measurement unit between metric and English, pick a UI language, modify the default frequency for info checkups and on-screen display time, as well as handpick the locations to display in the balloon message by scrolling a list.
Worth noting is that SharpWeather gives you the possibility to add multiple entries with different geographical locations to monitor at the same time.

Evaluation and conclusion

It worked well in our tests, without causing the operating system to hang, crash or prompt error messages. CPU and RAM consumption was low, so it didn't hog system resources.
On the other hand, SharpWeather hasn't received updates for a very long time and you are likely to experience compatibility issues on newer Windows editions. Plus, the interface needs some work in the graphical department. Nevertheless, you can test it for yourself if you're looking for a lightweight piece of software that shows weather details from any worldwide location.
