The polar vortex high above the Arctic has flipped direction, marking the earliest major sudden stratospheric warming in modern records. BBC Weather says such events have often raised the odds of colder, drier spells and snow in the UK, especially in eastern areas, as happened before the 2018 Beast from the East. Forecasters warn any effects are uncertain and could take weeks to filter down.
