Temperatures will fall by up to 9C across the UK in the next couple of days, the Met Office has predicted.

The UK heatwave will come to an abrupt end on Friday as a band of rain moves in from the west, and slowly works its way across Merseyside, Lancashire, Cumbria among other parts. The mercury is dropping though, and it'll be the coldest day for a while on Saturday. The change in temperature will be obvious for many, particularly those in Scotland - where the mercury exceeded 25C across the Scottish Borders on Tuesday.

But on Saturday, it will be between 8C and 16C across Scotland. The coldest areas, at 8C, will be in the Scottish Highlands, where Scots enjoyed temperatures of 17C on Tuesday afternoon. Even in the south of England, where the mercury reached 30C in Chertsey, Surrey, on Tuesday, temperatures will also be in the teens.

It'll be warmer in Eastern England and Southeast England, and colder in western parts, including Wales in the next few days. Temperatures in parts of north Wales will drop by 3c in the two next two days, the Met Office says.

Alex Deakin, meteorologist at the Met Office, says in a YouTube video on the service's channel: "There is still a lot of fine weather around (on Saturday) and then on Sunday, as that weather system starts to clear, there is the potential for some heavy showers across parts of the south, as well as across northern Scotland.

"The breeze coming in from the west or the northwest brings plenty more showers on both Saturday and Sunday, although by Sunday, that first low should finally be starting to clear away a little bit. Generally speaking, we're back much closer to average [temperatures] for the weekend across much of the UK. Temperatures will be much closer to average as we head through the end of June."

Rain on Sunday will be heaviest across Yorkshire and Humberside, though Northeast of England will see showers too. Parts of the Midlands may see scattered showers throughout Sunday evening.
