The Short Answer

Let's say you want to travel to Chicago from Atlanta by car. Can you predict your exact position at any given time? No. You can predict where you are going to be in the next few seconds but as you look further ahead you lose accuracy. Sure, you could say, "I'll be near Indy around 6pm on this road, but you don't know how fast you'll be going or what lane you will be in or how many cars will be around you." It is a similar idea. We can predict weather occurrences fairly accurately up close, but as we look further ahead, we lose accuracy.
