That reminds me of one evening several years ago in San Diego when the local TV weatherman opened by saying, "I was all set to come on and tell the viewers that, based on the latest computer technology, tonight and tomorrow will be fair and warm. But one of the producers suggested that I open the back door to the studio before I go on the air. And, now I know what all of you viewers know. It's raining cats and dogs out there." Whereupon, he threw up his papers and the station cut to a commercial. It was quite funny.
I’ve sometimes wondered whether weather forecasts are any more accurate than a random selection from actual observed weather on the same date in previous years would be. They do usually get reasonably close on temperatures, but for cloud cover and precipitation they’re often far off.
