Temperatures could plummet to "negative double figures" across parts of Britain this weekend - as "arctic air" and "drastic conditions" arrive. That's the stark warning from Alex Burkill, a senior meteorologist at the Met Office.
He says the cold snap is coming and Brits should be prepared for a "real drop" in temperatures. The Met Office has already issued a level three - also known as amber - cold weather alert between 6pm on Wednesday and 9am on Monday.
And Mr Burkill added: "We're going to see a real drop in temperature as cold arctic air plunges across the UK leading to drastic conditions. There is an incoming brisk easterly wind and by Tuesday even colder winds will come from a northerly direction, making it even colder."
