A 2,000 mile-wide Arctic front is bringing heavy snow and widespread frosts to much of Europe.
Met Office forecaster Steven Keates said: “Cold air from well north of the Arctic Circle, not too far from the Pole, is flooding to the UK and a good part of Europe as far south as Italy.
“-5C (23F) could be seen on Sunday morning in the north west, and lower still is possible on Monday morning in the west.”
Tomorrow will be the coldest May 6th since records began 178 years ago in 1841 if the mercury dips below the -5.6C (21.9F) recorded at Camps Reservoir, Scotland in 1980.
The Weather Outlook forecaster Brian Gaze said: “A polar plunge is bringing one of the coldest early May Bank Holiday weekends the UK has ever had.”
This weekend has already seen widespread frosts ravage delicate early-season crops across the UK.
And snow has even been reported in some parts of Scotland, N. England and Wales.
