termrain is a terminal weather application that combines detailed forecasts with an interactive rain radar. It presents current conditions, hourly temperature and precipitation charts, a seven-day outlook and radar imagery in a keyboard-driven interface.
The application uses the Kitty graphics protocol to display radar clouds over colour maps. It automatically selects JMA data for locations in Japan and Open-Meteo and RainViewer services elsewhere in the world.
This is free and open source software.
