It has been proved that the weather is unpredictable in the short term. One more reason for Britain lying directly below a jet stream delivering storms from the Atlantic. (If only Fitzroy knew that 🙂 )We can only establish some long term (seasonal) trends.
For example, in Greece it is known that “The ‘weather’ always comes from the West” whereas over here (UK) the direction is SW….There is evidence for this on the way that older trees are bent.

Do you mean bent like this? 🙂
