Pat,
FWIW, I've been told that what weather-persons mean when they say "50% chan=
ce of
rain" is that, it rained on 50% of the days on which weather patterns are
similar to the day for which the prediction is made (similar temp, humidity=
,
barometric pressure, etc, etc).
How do we accumulate this trivia...

UK weather forecasters have started using these percentage predictions=20
recently, I think borrowed from the US. The one that particulary irritate=

is when they cheerfully say "...and tomorrow there will be a 50% chance of=

rain"

Surely another way of saying this is "It may rain, then again it may not"

Why do people try to hide the fact that they don't know by using unnecessa=

statistics?

Just a thought
