Met Office Admits Can't Forecast Beyond Five Days
"..the science does not exist to allow an exact forecast beyond five days, or to absolutely promise a certain type of weather."
It said the UK is one of the hardest places to provide forecasts for due to its "size and location", making it "very hard to forecast much beyond a week".
However, it said its short-term forecasts are "extremely accurate".
The Met Office added that it would work towards developing the science of long range forecasting.
