"Some northern parts can expect temperatures down to -10C (14F), perhaps less, and will stay freezing all day. The UK Health Security Agency has issued yellow cold weather alerts to prepare responders to risk from the wintry spells. There'll be some dense freezing fog around too."

A snow and ice warning is also in place across northern Scotland until 10am, as travel disruption and difficult driving conditions could come from rain turning into snow, the Met Office said. The alert comes after a major incident was declared in Greater Manchester on Wednesday when flooding from heavy rain led homes to be evacuated and train lines to be closed.
