Temperatures are set to plunge to minus 8C in some parts of the UK as forecasters warn that nowhere will be “immune” to sleet and snow.
After a balmy Easter bank holiday weekend with temperatures soaring most will wake up to a cold start on Tuesday with the mercury hovering around minus 2C in the south.
Further north the cold climate will drop even further with lows of about minus 5C, plummeting as far as minus 8C in remote parts of northern and central Scotland.
Met Office forecaster Simon Partridge said wintry showers will sweep across Wales, south-west England, and down the east coast during the day.
He said: “Through the afternoon we might even get a few homegrown showers, so really anywhere [Tuesday] could catch a wintry shower by the time we get to the end of the afternoon.
“Nobody is entirely immune to the odd bit of sleet or snow.
“It won’t last long and it won’t settle for very long either, but nobody is going to be 100 per cent safe from not seeing anything.”
Snow warnings remain in place for northern Scotland until 10am, with as much as 2cm falling in higher areas.
A separate yellow warning for snow and ice is also in place for west Wales and Northern Ireland also until 10am, with up to 4cm expected to fall.
Temperatures are forecast to scrape to highs of just 8C in the south of England, and between 4C and 5C in the north later on on Tuesday.
But Mr Partridge said the wind chill will see most of the south feel “a couple of degrees above freezing”, while in Scotland the temperature will feel around minus 5C.
Tuesday night is forecast to be the coldest this week, with the mercury plummeting to minus 5C in southern and central England in the early hours of Wednesday morning.
In the north of England and into Scotland, temperatures are expected to hover around minus 6C to minus 8C.
Wednesday will be a mostly dry day, with temperatures forecast to be around 8C to 10C in the south.
