| "But
that isn't what they said yesterday!" Whenever we're
looking forward to a few days dry weather it always seems to disappear
from the forecast just before we set off. Never mind whether the
forecast is actually right for any given day; does the forecast
itself keep changing?
To investigate the matter
here's a log of the forecast for
Manchester. Everyone knows that the weather in April is
changeable. Now we can reveal that what the Met Office says about any given day
is
twice as likely to change as it is to stay the same, i.e only 11 forecasts out
of 32 remained unchanged from the previous day.
