Saturday began with temperatures widely below freezing in parts of England and Wales.
Temperatures in South Newington, England dropped to minus 7.2C, the lowest recorded temperature in the UK so far this autumn.
In Wales, readings bottomed out at minus 6.2C in Sennybridge.
Motorists should be alert for some patchy freezing fog which forms in air that is below freezing.
Super-cooled water droplets remain suspended in the air and it can be particularly dangerous as they can freeze on impact turning untreated pavements into instant ice rinks.
Yellow cold health alerts from the UK Health Security Agency (UKHSA) are in force for the West Midlands and north-west England until 12:00 Saturday, external.
After the fog and frost clears, Saturday will largely become a bright and dry day.
By the afternoon, temperatures will rise across the UK – ranging from 7C in parts of the Highlands to a milder 12C in south-west England.
England and Wales are forecast to see long spells of sunshine, away from the odd shower early on in the far north-west.
Northern Ireland will have some bright spells in the morning, with thickening cloud in the afternoon and rain by evening.
A few showers are expected in parts of Scotland where is will also be a breezy day, and will feel colder due to the wind chill.
