A home weather station will allow you to make your own accurate weather observations by directly observing atmospheric conditions such as temperature, humidity, barometric pressure, wind direction and speed, and precipitation amounts.
Today a very affordable home weather station rivals equipment which was just a few years ago only available to big government and commercial weather forecasting stations.
Your home weather station will provide you high quality scientific measuring instruments that will allow you to be in the know about the coming weather. In most basic models it will include a thermometer, barometer, hygrometer. More advanced models add wind speed, wind direction, and precipitation totals.
Learning about predicting the weather is a great educational experience and pastime. Its a great way for a family to learn about predicting the weather from current weather conditions.
