Plug it in, and you're done! No sensors, no set up, no hassles. This weather station uses the MSN Direct service to receive regional weather information without the use of any outdoor sensors. Users can get real-time, 4-day weather forecast information, including the chance of precipitation. They can also receive current regional weather data, including temperature, humidity, UV Index and a unique "feels like" temperature reading that combines temperature and humidity into one easy reading. A radio-controlled clock/calendar also displays today's sunrise and sunset information, all within a sleek black case.
