The Guardian has confirmed that Britain's unseasonably warm weather is now coming to an end, meaning it's time to put the shorts and t-shirts away.
The 18.6C highs of last weekend will tumble as a cold front starts pushing towards Scotland, Northern Ireland and northern parts of England/Wales.
Andy Ratcliffe, a forecaster at MeteoGroup - the weather division of the Press Association - spoke to the Independent about the looming icy weather.
He said: "There's a cold front today pushing south across Scotland, Northern Ireland and into northern England and Wales. It looks like there will be strong gusts of wind of up to 70mph along the cold front too.
"The cold front will also give some large rain falls," Ratcliffe added, highlighting the need for people to wrap up warm with rugby jumpers, scarves, hats and woolly gloves.
On Wednesday night, temperatures will plummet to an icy 1C (33.8F) and could hit as low as 30.2F in other areas of the UK. "It's going to be pretty cold everywhere across the UK on Wednesday night, with widespread ground frost expected in the whole of the UK and perhaps air frost in places too," warned Ratcliffe.
It is hoped that after the cold front passes, slightly warmer weather will traverse the Atlantic to our shores - but it will be nothing like the earlier Indian Summer experienced.
