Here is the BBC "Blog" with the latest information regarding the change of weather supplier from the UK Met Office to MeteoGroup.
"Some things won’t change though. We know how fond people are of our weather presenters. We have taken steps so the vast majority of our well known and much loved presenters will continue to front BBC Weather.
We’ll still work closely with the Met Office on severe weather warnings; the national agencies for flood warnings and the Maritime and Coastguard Agency on shipping forecasts and coastal information."
The announcement says that the changes will take effect from the spring of 2017.
An item in "The Guardian",
here, mentions some of the on-screen forecasters presently employed by the Met Office.
The article also gives an account of the business-history of "MeteoGroup", having started as part of the Press Association, before being sold off in 2013 to "General Atlantic".
Here is MeteoGroup's Press announcement.
"Founded in 1986, MeteoGroup has thirty years’ experience of delivering weather solutions to the media and other weather-critical markets worldwide. Here in the UK, MeteoGroup has more customers than any other commercial weather company, including national broadcasters, regional and national press, energy, offshore and shipping companies. The majority of the UK’s roads network also rely on MeteoGroups’ winter forecast services. "
