Temperatures are set to plunge as low as -3C in parts of the UK this weekend as cold air from Scandinavia hits the country.
Many areas are expected to wake up to widespread frosts, while bitter winds are also forecast as the country remains gripped by chilly conditions.
Met Office forecaster Grahame Madge said: “There will be frost overnight in some places and that will be a consequence of the colder air that will be over the UK.”
The mercury is set to plummet as low as 0C overnight in London and the South East while in the Scottish Highlands it could be as cold as -3C.
This weekend will be “mostly dry” for many across Britain, forecasters said.
The cooler air is thought coming over from Scandinavia and central Europe, Mr Madge said, although he added it is not unusual for spring to see temperatures such as these or for a brief cold burst to hit.
Conditions across the country are set to warm up again by midweek, he said.
He said: “We would expect to see temperatures of about 12C or 13C again.”
According to the Met Office, the outlook for Sunday to Tuesday will be: "mainly dry and rather cold with sunny spells on Sunday.
"[It will be] turning windier in the north and west, with patchy rain possibly arriving in the west next week. Becoming somewhat warmer."
