What was it like outside when you left your house today? Cool and windy? Hot and sunny? That's the weather: the conditions of the air, or atmosphere, around you where you are, right now. Weather is always changing. It can be rainy one day and sunny the next. That's why we depend on weather forecasts to tell us what the weather will be like from day to day.
