UK forumites may or may not be aware that BBC is moving from the Met Office to a new weather provider, Meteogroup. They were supposed to take over the BBC weather contract last spring, but have been having tech issues. The change-over looks like it must be getting close, as the BBC now has two weather websites running in tandem. The new updated website has its data coming from Meteogroup, so the BBC now has two different forecasts https://www.bbc.co.uk/weather/0/2640729 (Note the /0/ in the URL, which is the trigger to view the new website).
Nice to see rainfall likeliness given as a percentage. The satellite map forecast graphics look like an improvement.
I can't find a new iOS or Android app (yet)
