Description:
WindowMaker dock app that shows your current weather
wmweather+ provides a monitor on a 64x64 mini window that displays the current weather conditions, forecast data (US only), and optionally a radar image. It will also watch for various warnings and display them using an external command. . wmweather+ is designed to work with the WindowMaker dock, but will work with other window managers as well. Think wmweather with a smaller font, forecasts, a weather map, and a sky condition display.
