The UK is set to experience wintry weather as Arctic air moves southward, bringing potential snowfall, particularly in northern Scotland and higher ground. The Met Office warns of accumulating snow of 5-10cm in northern Scotland, with lower elevations also facing risks of snow and ice. This cold snap coincides with the Leonid meteor shower, providing a chance for clear skies. Weather warnings have been issued for northern England and southern Scotland as the weather system from the Atlantic could disrupt conditions further.
