Weathercast → It is formed from "weather" (from Old English *weder*, meaning atmospheric conditions) and "cast" (from Old English *castian*, meaning to throw or to broadcast). The word "weathercast" refers to the act of broadcasting information about atmospheric conditions.
Think of 'weather' as the atmospheric conditions being 'thrown' or 'broadcasted' — that's what a weathercast does.
