The MET office predicted a barbecue summer and a mild winter.. this is
Murphy reminding us that their mathematical models aren't very good.

The models are OK, but the solutions are chaotic.

They start to diverge from reality 3 days out significantly.

The models are bad, they don't know the starting conditions well enough.
The best they can do is run lots of slightly different conditions and see if
they diverge or not.
