Weather forecast

A weather forecast is a prediction of what the weather will be in the future. Weather stations measure things such as temperature, air pressure and cloud cover. Meteorologists use these measurements and fluid dynamics and other methods to predict the weather. A forecast for many days in the future is less trustworthy than one for tomorrow or the next day.
