Valentine’s Day is set to be a whiteout as a 1,500 mile wide snowstorm sweeps across Britain, making it colder than Finland.

The Met Office warned Britons to prepare for an “Arctic assault” as a massive weather front swept across the country, bringing snow and sleet showers on Wednesday.

Temperatures are expected to drop to -5°C, making Britain colder than Finland where it will be -3°C.

Meteorologists also predicted a second cooling with more snow around Valentine’s Day.

Three more chills – each with snow and below-average national temperatures – are expected later in February and early March.

We are here to come again from December to January, to hear from the former forecaster of the BBC and the Met Office, John Hammond.

I said: ‘A dive in arctic air is set to sweep across the UK later in the week which could well see hard frost and snow.

“The temperatures to come are expected to be on average rather lower than those for most of winter, with more frequent incursions of arctic air.

“A wetter, colder mix looks likely as we head into March. Late snow is a possibility.

It comes as the Met Office warned of ‘colder interludes’ until March 6.
