Britain could plunge back into a bitter winter by the end of this week after a month of mild temperatures.
The change in the weather is predicted to blow across Britain on Tuesday morning, according to the Met Office, with patches of rain forecast and overnight temperatures set to drop.
Frost could cover some of the UK's road on Wednesday morning, but daytime temperatures will hover around 5 to 6C.
Temperatures have been unusually mild for the last few weeks, leading to dozens of snowdrops appearing earlier than expected.
Forecasters are predicting a progressive drop in temperature as the week goes on, with a low of -1C possible.
A Met Office spokeswoman told HuffPost UK: "The colder weather means temperatures are more like what people will expect at this time of year. it's been very mild so people will notice it getting colder.
"It's the latter part of the week which will be when it turns colder, around 2 to 3C in the north and around 5C in the south.
"It'll be that wintery sun, dry and bright conditions, but it does mean it will feel colder. There's a small chance of snow, but only in the Scottish Highlands and the Pennines."
