Britons will now be able to moan about the weather in more precise terms thanks to new supercomputer software that the Met Office is installing.

The new software called ENDGame, which has been 10 years in development. The Met Office claims that the hardware will transform the accuracy of weather forecasts.

The Met Office has a long history of getting it wrong. It was under fire last November after reassurances that it would be “drier than usual” preceded the wettest UK winter since records began. In 2009 a predicted “barbecue summer” turned out to be a complete washout.

After the barbecue summer prediction, the Met Office pointed out that its forecast offered only a 65 per cent chance of being right. The hope is that ENDGame, along with the supercomputer, will give an 80 per cent accuracy.

Despite its many gaffs, the Met office claims that its four day forecast is now more accurate than the one day forecast of a few decades ago.
