If you live in an area that's prone to hazardous weather conditions, such as hurricanes or tornadoes, home weather stations can provide you with an advance warning far faster than a local weather forecast can, especially if you live in a more rural area. Beyond providing a heads up against dangerous weather patterns, home weather stations can give you localized data on humidity and rainfall if you're an avid gardener. For others, monitoring the weather is a fun hobby. Measuring rainfall and wind direction can be a fascinating look into your local meteorology. You can even contribute that data to a number of crowd-sourced weather services like Weather Underground.
