The probability of correct forecasting is something that has been
rattling around in my head for a while.

If on Day 1 of a 5 day forecast I'm told Rain is on the way only for
this forecast to change between rain/dry (for example) *over the next
three days and then its actually dry on day 5, the forecast on day 1
was utterly worthless.

What probability of a likely event happening triggers it becoming a
'forecast'. Surely it needs to be 75% likely as that would mean it is
twice as likely to happen, as not.

Also why is that probabilty of a forecast never mentioned on tv/radio/
media forecasts. Is it because Jo Public has dumbed down so much over
the last few years that he has no concept what Porbability is?

To be fair, as Victoria Coren wrote in the Observer last Sunday:
The Met Office recently had its budget cut by £4.3 million. That may
not sound like much, but it was a loss of more than 20 million pine
cones.

OK Graham,
I know you've got superior seaweed in Cornwall!
But I am not sure the Mousehole Barometer is foolproof.
