I read somewhere that if you forecast every day that tomorrows weather would
be the same as todays, you would have a success rate comparable with the
forecasts on TV.

Not quite. The probability of tomorrow's weather being the same as
today's is in the region of 67%. This means the forecasters have the
challenging task of improving and getting the forecast into the rather
narrow gap between 67% and 100% - ie, don't be too scathing, it's a
difficult task they have there. It's always easy to improve something if
it's really bad to start with, less easy to improve something which is
already rather good.
