Britain was colder than the Arctic Circle overnight – and snow could be headed our way next week.
Temperatures in South Newington and Benson in Oxfordshire plummeted to minus 7C and minus 6C respectively.
The city of Tromso in Norway, however, basked in a relatively balmy minus 1.4C, according to forecaster Callum Stewart, of MeteoGroup.
He added of the UK weather: “The coldest temperatures were in England. Oxfordshire was the coldest county.”
Temperatures are expected to lift into double figures this weekend, with milder conditions sweeping in from the Atlantic triggering a stormy start to next week, forecasters warn.
Parts of the country face severe gales, heavy rain and thunder from Monday as the topsy-turvy weather dishes up its latest twist.
Thermometers will start to rise across the country tomorrow with highs of around 10C in the south and 8C further north.
But Britons are warned to make the most of the mild respite with another chilly blast threatening to hit next week.
Yet another u-turn in the weather will bring cold winds in from the Arctic region – putting parts of the country on alert for snow.
The Met Office said although it is turning milder it will be cloudy and rainy at times over the next couple of days.
Forecaster Emma Sharples said: “There is a lot of cloud around at the weekend so we are not going to see the bright conditions that we saw this week.
“It is turning less cold with temperatures broadly above average for the time of year although there might be the odd spot of rain.
“It is turning unsettled into next week as an area of deep low pressure moves towards the UK, Monday could see gales or severe gales in parts with squally showers, thunder, hail and the risk of snow in Scotland.
“There are signs it is turning colder again later next week as winds start to come in from the northwest.”
This week saw England and Wales shiver in the coldest night of winter so far after temperatures dropped to -8.1C in Benson, Oxfordshire, on Wednesday.
Swathes of the country have woken up to harsh frosts and icy windscreens while motorists faced chaos on the roads.
Britain’s weather has continued to keep bookies on their toes with some forced to slash the odds on this winter being the wettest ever.
Coral is offering 4-1 from 6-1 on rain records for the season being toppled with 8-1 on the cold winning out.
Spokeswoman Nicola McGeady said: “The latest betting suggests that the freezing temperatures will be washed away by torrential rain early next week which has left us running for shelter as bets flood in on the wettest winter on record.”
WeatherOnline forecaster Simon Keeling said: “It is becoming milder during the weekend but also rather cloudy for most.
“It will be mostly dry with the risk of some drizzle on western coasts and hill before turning more mixed next week and windier too with cooler air arriving at times in Scotland.
“Perhaps becoming cooler more widely towards the end of the week.”
Meanwhile, the Met Office has issued a yellow “be aware” warning for drivers in London and south-east England for ice.
It said freezing temperatures overnight, coupled with showers in some areas, could lead to “difficult driving conditions on untreated surfaces, and slippery conditions on pavements and cycle paths are possible”.
A statement on the Met Office website said: “Although many surfaces are now above freezing, some remain below and it is possible in these areas for some icy patches to temporarily develop this morning where showers fall on untreated surfaces or where showers have resulted in wash-off of previous treatment. Any ice should clear by 10am.”
Mr Stewart added that conditions were set to get milder into the weekend and the early part of next week, with daytime highs of up to 10C or 11C in southern parts of the UK.
