Brits should get their woolly hats and blankets ready for what could be the chilliest night of the year so far. Temperatures are set to fall as low as -10C, making us temporarily even colder than Iceland. Brrrrrr.
The wintry weather is a step up from last week's chill-fest which saw snowfall in parts of England and Scotland and even floods sweeping across the North.
The Met Office's basic forecast for the country tonight says parts of the UK 'will be windy with widespread frost'. So drivers, get your scrapers out.
"Showers in the north and close to western and eastern coasts will be wintry at height and could lead to icy roads," the national weather service warned.
Temperatures are set to plummet even lower at the start of Thursday, 'with sunshine in the west, and wintry showers in the east'. The Met Office advised that snow in the east could affect towns as far south as Suffolk.
It's predicted that this winter could be even colder for Britons than the winter of 2009-10, which saw the coldest winter in the UK since 1978-79, severe snow and record low temperatures.
The Arctic weather, which is now nicknamed the Big Freeze, caused widespread travel chaos, power failures, sport cancellations and even 25 deaths.
Government health agency Public Health England has warned vulnerable people to wrap up warm and stay careful to make sure they don't fall ill, so stay safe out there.
Dr Thomas Waite, of PHE's Extreme Events team, said: "We know that more deaths occur every winter in the UK than in the summer due to a wide range of causes including cold weather, influenza and other respiratory infections.
"If we all keep a close eye out for each other over the coming months hopefully we'll all be able to stay well this winter."

Met Office forecaster Helen Roberts confirmed that this week will get colder as it goes on, with temperatures expected to plummet overnight into Thursday.
"A return to cold is the theme for this week - cold, breezy with a return of widespread overnight frost and wintry showers predominantly around the coastal fringes of the UK," Roberts said.
"We will potentially have some lying snow across the hills of Scotland and northern England and that always helps to keep temperatures down, so we could potentially see temperatures as low as -8C (17.6F), possibly -10C (14F), across parts of Scotland where there is lying snow by Thursday night."
Roberts added that we could even see temperatures between -6C and -8C in hillier parts of England and Wales.
Railway companies have warned commuters to check their journeys before travelling as trains may be affected by the wintry weather conditions. Might be best just to stay home and make yourself a nice hot beverage, then.
