Cold weather warning in force as temperatures plummet
The UK Health Security Agency's issued it for areas across the north-east, north-west, Yorkshire and the Humber and the south-east
A yellow cold weather warning is coming into force as temperatures are set to plummet as low as minus 7C.
There is a chance of icy patches developing over the coming days, which could be a hazard, especially overnight.
Yellow cold health alerts have been issued by the UK Health Security Agency (UKHSA) for a number of areas across England including the North East, North West, Yorkshire and the Humber, and the South East from 9am on Friday (7 February) until 9am on Tuesday (11 February).
This means the weather is likely to lead to an increased use of healthcare services by vulnerable people, and a greater risk to life of vulnerable people.
Stephen Dixon, spokesman for the Met Office, said: "What we're seeing with the UK's weather over the next few days is the influence of high pressure and the development of south easterly air flow which will see temperatures drop for many.
"We could see temperatures drop as low as minus 7C in rural parts of Scotland from Friday into the weekend.
"Further south we're still likely to see through the weekend sub-zero temperatures.
"Rural parts of southern Wales could reach minus 4C from Friday overnight into the weekend."
Mr Dixon said it would be a "cold period" but not "historically noteworthy".
Day-time temperatures will be "slightly below" the average maximum for February which is 7C, he said.
Mr Dixon continued: "February has started warmer than average, so it's going to be a return to more typical February averages, albeit a bit colder.
"From Friday, there's a chance of some snow drifting in to parts of the south of England and south Wales, however, this is relatively short-lived, it's not expected to be impactful at the moment."
He said higher ground in south Wales could see a couple of centimetres of snow.
Saturday is likely to be a grey day for many, drier in the north but rain for many in the south of England, while showers will continue on Sunday but it will be a bit drier, according to Mr Dixon.
There is also a chance of wintry showers on Monday, which is something the Met Office is keeping an eye on, Mr Dixon said.
