Use the La Crosse Technology Wireless Forecast Station with Weather Tendency Indicator - Black as your alarm clock and be greeted with all the weather information you'll need for a comfortable, successful day. An extremely accurate atomic clock displays the time in 12 or 24 hours and includes a handy alarm with snooze. The outdoor sensor wirelessly relays weather information back to the receiving unit by 915 Mhz transmission and can be placed up to 330 feet away from the receiver. The easy to read LCD screen can be hung on a wall or propped up on a table with its foldout stand. In addition to the current indoor and outdoor temperatures, you can check the recent min/max temperature records. The barometric pressure arrow also informs the weather forecasting function, which uses three weather icons and a weather tendency indicator.
