There is a “real chance” snow could blanket Britain in weeks, the Met Office said.
Cooler temperatures have begun to set in after a mini-heatwave in September when it was even hotter than the South of France.
Now the Met Office has warned snow could hit other parts of the UK in weeks after it arrived in Scotland.
Icy temperatures are predicted to drop to 10C in Yorkshire as October gets colder.
However, the forecaster said it was not “uncommon” to get snow this time of year.
Senior meteorologist at the Met Office Greg Dewhurst told The Mirror: “We’re now entering the time of the year when the change in conditions becomes really noticeable.
“As we enter October it certainly will get colder. Although snow is not forecast imminently, there is always a real chance in the weeks ahead. It is not uncommon at this time of the year.
“We have already seen snow in Scotland, and we could see some in other parts of the UK further down the line.”
Meteorological expert Dave King delivered “bad news” about the icy weather freezing the UK.
He said on This Morning: “It is gonna be bitterly cold and very frosty.
“That’s bad news for people with gas and electric because your bills are going through the roof.”
Warm weather arrived in September after Londoners faced freak flash flooding over the summer.
