The Celestron Compact Weather Station displays the weather forecast but it does not have a barometer, so it is just an indication for reference, and may not be accurate. The station will display sunny, partly cloudy, cloudy or rainy icons. The receiver does display both indoor and outdoor temperature, from data it retrieves from the included remote sensor. The unit also displays indoor and outdoor humidity, since it has a built-in hygrometer.
The Weather Station provides useful information, including the moon phase. It also stores minimum and maximum, indoor and outdoor temperatures in its memory. You can set the alarm to go off when a certain indoor or outdoor temperature is reached. Besides all this the Compact Weather Station has a built-in digital quartz alarm clock with snooze alarm and a calendar that shows month, day, day of week.
