Weather experts said that the temperatures are likely to plummet to -3C after the UK experienced a balmy weekend. Talking to the Mirror, former BBC and Met Office meteorologist John Hammond says the UK’s weather “will go into reverse” this week.
He said: “The mercury will go into reverse, with a cooler trend to end April.
Fresh waves of Arctic air mean a good chance, even across southern Britain, of temperatures falling close to or below freezing.”
Mr Hammond added: “One or two wintry showers are not ruled out later in the week, most likely on higher ground in the North.”
The sub-zero drop will mean the UK is even colder than Stockholm’s 3C nights, with the freezing forecast set to last seven days into the May Bank Holiday weekend.
Consultant meteorologist Matt Hugo said: “Will it be the coldest start to May in quite some time? Northerly weather into early May is gaining traction.”
Some may manage to escape the icy blasts however, with London forecast to enjoy a few days at 17C.
Elsewhere, a north-easterly wind-chill will mean highs of 11-16C will feel more like 9-14C.
The Met Office said it is likely to be “chilly” overnight in the run-up to May, with rural frost setting in some areas.

“Moving through the period, the weather is likely to become more unsettled in northern and perhaps some central areas, bringing spells of rain and potentially some cooler air at times, whereas it’s probable southern areas will remain more settled throughout.
“Temperatures are likely to be above normal for the rest of the country.”
