Why can't weather forecasters get it right?

Question

This morning I looked up the Bureau of Meteorology website (Australia) and the next 4 days were listed as 'fine'... now (14 hours later) it's saying 'possible storms' for all 4 days! What the?

Answer 1

Because it is so complicated.

This is known as the butterfly effect...

and it means that tiny things changing the air CAN have disasterous concequences later on. That's chaos.

Answer 2

When you think about it, the only other "forecasters" you hear about are psychics and Stock analysts, and they're equally wrong usually. Nobody knows what the future brings, except the Shadow knows.
