BRITAIN will be hotter than the Algarve today as the mercury soars to 18C - but a cold snap will sweep in this week.
Sunday will be filled with sunshine as the relatively balmy temperatures continue, before the weather takes a drastic turn on Monday.
Forecasters say the heat in London will reach 18C with some sunny spells, while the Algarve manages only 17C - with plenty of showers thrown in.
The recent heavy rain in Spain and Portugal has put a dampener on Brits' holidays after thousands jetted off for an Easter break.
Sun worshippers have been able to make the most of this weekend in the UK by basking in the sunshine on beaches and in parks.
Northwest England, western Scotland and Northern Ireland are set to get the best of the sunshine.
Those in the east and south of the country were told to expect "sunny spells and scattered showers".
But the warm weather will abruptly come to an end on Monday, with the Met Office warning of a sub-zero plunge at the start of the next week.
London is expected to face temperatures as low as 4C, while parts of the north, Scotland and areas in Belfast could drop to below 0C.
WXCharts are even predicting snow before the end of April, hitting the north of Scotland on Friday April 29 and the south of England and Wales from Sunday May 1.
The dip follows from the hottest day of the year so far, recorded over the bank holiday when temperatures rose over 23C in London.
Forecaster Tom Morgan warned that the cold weather isn't "great news for gardeners".
He told : "They may have spent the weekend planting beneath the sun but we could see patchy frosts by Wednesday which could undo all of their hard work.
"Some rural spots could drop to -3C through the first part of the week.
"It will feel more spring-like during the day, despite the occasional showers, but not in the mornings or overnight."
Advanced weather modelling maps show that the UK could be in for some shock flurries of snow at the start of next month.
The first band of snow will sweep in across the north of Scotland late on Friday April 29, before moving down the north-east coast of England on Saturday, April 30.
May then begins with widespread snow across the United Kingdom, with flakes falling in the south of England and Wales on Sunday and Monday, May 1 to May 2.
Snow will hit Scotland in the early hours of May 1, starting in Inverness, Aberdeen and Edinburgh before slowly moving southward throughout the day.
Newcastle, Manchester and Birmingham could follow with millions of Brits in northern and central England set to see some of the white stuff.
