Scorching hot temperatures will dominate the bulk of the weekend before a dramatic temperature swing beckons in large tracts of frost.
The UK is set to enjoy an unusually shaped Bank Holiday weekend, with the extra day off coming on Friday rather than Monday.
The change was planned by the Government so the country can mark the victorious end of WWII.
While the day is not one of celebration exactly, the bitter-sweet occasion will be aided by a day of warm weather and sunny spells.
On Saturday things will continue to be warm and pleasant as the UK edges closer to an expected easing of the coronavirus lockdown.
Things really begin to unravel weather-wise on Sunday however, when a cold front from the north threatens frost and snow.
Here's what to expect from this weekend.
Friday
The 75th anniversary of the end of WWII will arrive with most of Britain under a light covering of cloud.
The west of the country will have the worst of the weather, with the south west of England and the far reaches of the western coast of Scotland in line for some rain.
Working across to the eastern coast dark rain clouds will be replaced by a sparser covering that will allow more sunny spells to come through the closer to the North Sea you are.
As the afternoon arrives temperatures will begin to warm across the UK.
The south east has the best of it, with the mercury edging up into the low twenties celcius and possibly maxing out at 26C in London.
Scotland and Wales will be closer to the middle teens, while the north of England, Midlands and Wales will be nudging the 20C mark.
Glasgow and Edinburgh are likely to reach a high of 19C, while Exeter, Plymouth and Birmingham will touch the 20C mark.
Manchester, Belfast and Leeds will be a touch cooler at around 19C.
Come Friday evening and the sunshine will have banished all but the most stubborn clouds, which will have migrated to the north east of Scotland.
While they may threaten to dump a little drizzle there, the rest of the country can enjoy a warm, dry spring evening.
Saturday
The weekend begins in proper with sunny spells across most of the British Isles.
A band of light cloud across the midlands and heavier, more overcast weather in north Scotland are the only exceptions to an otherwise lovely morning.
Consistent periods of sun will bring the temperature up into the twenties for the whole of the southern part of the UK, with things only marginally cooler in the north of England.
The cloudy weather will slowly makes its way down from the top of Scotland as the day goes on, covering Glasgow and Edinburgh in the middle of the afternoon and northern England by the evening.
People in the north west of England and Midlands may experience light drizzle at around 7pm on Saturday, while heavier bursts are expected throughout the evening in the Highlands.
Ollie Claydon, Met Office spokesperson, told Mirror Online: "Saturday will bring some much colder conditions through the north as we go through the weekend.
"Scotland will be under some pretty persistent rain throughout the day and will feel it as cold air comes in from the north.
"It will be a day of sunshine and showers for the rest of the country."
Sunday
Sunday will prove a much gloomier prospect than the two days before.
Dark cloud will hang over the whole of the country aside from northern Scotland, where the sun may break through the wispier covering.
Belfast may enjoy brief spells of sun in the afternoon on an otherwise disappointing way to end the Bank Holiday weekend.
Temperatures will feel frigid throughout the day.
In Scotland it is unlikely that anywhere will experience anything out of the single digits, while the North of England, Midlands and Wales will be stuck around 8 or 9C.
Only the south west is expected to enjoy the relatively balmy heights of 14 or 15C come early afternoon.
Things will be much colder in London on Sunday compared to Friday, with the highs having dropped from 26C to around 15C.
Leeds and Newcastle will feel bitterly cold and max out at 8 or 9C, while Aberdeen will be positively Baltic at around 6C.
Mr Claydon said: "There will be an increased amount of rain through the day and wintery snow showers moving into the north.
"The north east of Scotland and England can expect some snow showers later in the day. By Monday morning there will be widespread frost.
"There will be a 10C swing in temperatures in some parts of the country from Friday to Sunday."
