The weather is displayed on a white screen using a dial that spins through icons of different conditions (clouds, sunshine, rain, etc.) before resting on the day’s forecast. Below, a few words tell you the forecast and temperature, e.g. “It’s Cloudy 77°” or “It’s Sunny 85°”. Then there’s a seven-day forecast with small icons and temperatures, with a slider at the bottom that lets you switch between °F and °C.
