The temperature is expected to drop to as low as minus 2C in some parts of Scotland ahead of the Bank Holiday weekend.
It comes just a few weeks after the warmest Easter Monday on record.
However, temperatures are set to plummet in the north of Scotland on Saturday evening, with heavy showers and hail also expected on the UK's east coast.
Aviemore is expected to be the coldest part of the UK with temperatures falling below 0.

Met Office forecaster Richard Miles said: “It will be colder, a lot colder, with showers in the north and the east of England.
“Saturday will be the worst day of the Bank Holiday weekend in terms of chilly showers and possible hail on the east coast, though Sunday and Monday will be a lot more settled.
“Sheltered, hilly areas in the North and Scotland could see colder and wintry weather in the evening from a northerly direction.

“The West should escape most of the colder weather, in Wales it could actually be quite nice, normal weather and the same in parts of Northern Ireland, as most places go to double figures during the day.”
The lowest temperature ever recorded on the early May bank holiday was minus 6.4C (20.5F) in Grantown-on-Spey in Scotland in 1981, and in Kinbrace in Scotland in 1988.

Asked about the chances of it being colder than that weekend, Mr Miles said: “You’d be unlucky to see weather that cold, though some sheltered areas will feel very chilly.
“The coldest looks to be Aviemore in the Scottish highlands, which could drop to minus 2C in the evening, with frosty weather in the hilly areas.”
