The Met Office has confirmed that it has lost its weather forecasting contract with the BBC.
The loss of the contract marks the end of an era, as the UK weather service has been providing data for the BBC's forecasts since its first radio weather bulletin in November 1922.
The BBC explained that the decision was based on its legal requirement to provide licence fee payers the best value for money.
A spokesman for the corporation said: "Our viewers get the highest standard of weather service and that won't change.
"We are legally required to go through an open tender process and take forward the strongest bids to make sure we secure both the best possible service and value for money for the licence fee payer."
This means that the BBC will now tender their weather contract to other weather services, with a replacement for the Met Office expected to be in place next year.
Steve Noyes, operations and customer services director for the Met Office, described the news as "disappointing".
"Nobody knows Britain's weather better and, during our long relationship with the BBC, we've revolutionised weather communication to make it an integral part of British daily life," he said.
"This is disappointing news, but we will be working to make sure that vital Met Office advice continues to be a part of BBC output."
A BBC spokesman confirmed that the corporation will still be using the Met Office's severe weather warnings.
It is not yet known what will happen to the BBC's weather presenters, many of whom are provided by the Met Office. The service said they would support the presenters to "ensure clarity on their future".
The BBC and Met Office last renewed their contract in July 2010.
