Have you ever seen a double pendulum before? If you drop it twice from pretty much the exact same height, due to extremely tiny differences that add up over time, the outcomes turn out completely different, making it extremely unpredictable. Same thing goes for weather.

The Short Answer

Have you ever seen a double pendulum before? If you drop it twice from pretty much the exact same height, due to extremely tiny differences that add up over time, the outcomes turn out completely different, making it extremely unpredictable. Same thing goes for weather. Really minute details can cause huge changes later on. It's hard to predict the weather when the tiniest detail can change everything later on. One extremely small oversight or miscalculation gives you completely different results.
