There are quite a few weather applications for Linux desktop. GNOME, the default desktop environment for Ubuntu, Fedora, and some other Linux, also has a core weather application.
With the core weather app, user can either open the app window to get current weather condition, hourly and daily forecast, or open the clock menu to see the weather forecast for next hours.
To make life easier, there’s an extension which also add current weather condition and temperature in center of top panel. So, user can get a glimpse of it and date time by looking up.
