Prior to July, 1995 ZetaTalk stated that Weather Predictions would be inaccurate, based upon the wrong parameters. On Jan 27, 2000 a new supercomputer was failing in just this manner, and admissions continue to be made.

Daft Computers Still Fail to Understand Weather
Computers Fail to Notice US Snowstorm
The Times, Jan 27, 2000
It sounded phenomenal a week ago, as American meteorologists unveiled a supercomputer capable of 2,500 billion calculations a second that would give them warning of impending weather problems up to ten days inadvance. As it turned out, the new marvel failed to notice a huge snowstorm until it was almost on the doorstep. By yesterday, as the paralysed East Coast of the United States dug out from South Carolina to Massachusetts, there was much hand-wringing among weather forecasters over their misreading of the size, intensity and course of the storm. For a second day, the federal Government remained closed in Washington. So, too, did hundreds of schools and businesses. Airlines struggled back into operation, but delays were horrendous. The new IBM supercomputer, running an array of programmes said to be the world's best for weather forecasting, had digested reams of data from balloons, satellites, ships and ocean buoys on Monday. At 3.30pm,the National Weather Service announced: "A 40 per cent chance of light snow. Total accumulation: less than one inch." It was not until 10pm that forecasters issued their first winter storm warning, but by then it was too late. Most Americans get their weather forecasts from the early evening television news.

BBC Look North weatherman Paul Hudson said: "All I can say is it went wrong. We have Supercomputers and we ran the information through them 52 times and all 52 solutions did not predict the snow."
