Snow could hit parts of the UK this week as temperatures are forecast to plummet over the coming days.
The Met Office said temperatures will fall below freezing overnight and during the day will halve from the highs reached last week.
It comes after many areas basked in glorious sunshine and highs of 20C over the past few days.
Alex Burkill, a Met Office forecaster said: “Wednesday will be the most extreme in terms of wintry weather, as a cold stream of air will start to push southwards bringing unpredictable wet and windy conditions, even snow or sleet.

“It will be markedly colder than what we’ve just seen, daytime temperatures falling by half, and some areas will even struggle to hit 8C, which will signify the biggest change in conditions.
“Overnight into Thursday and Friday, many areas will fall considerably lower than freezing, towards minus 4C and minus 5C.
“It looks like most places will be impacted, parts of northern England, northern Wales and central England are expected to be the worst affected.
“This wintry weather could even push into southern areas of England and Wales, which isn’t unusual, it is normal to have colder weather in April, but it’s far from the sunny, warm days seen last week.”
Sunday began cloudy and chilly for many parts of the country, but is expected to reach highs of 15C later in the day.
During the evening, cloud will begin to spread eastwards, bringing showers, dense patches of fog and frost.
