Parts of the UK could face disruption on Friday morning, amid warnings of wintry showers and plunging temperatures.
Parts of eastern England, Kent and Scotland have been blanketed in a layer of snow, but forecasters say another 5cm (2ins) could fall in some areas.
The Met Office has issued a yellow weather warning for ice and snow over eastern England and Scotland.
It urged people to be careful on roads and pavements.
The warnings are in place until 10:00 GMT on Friday.
Overnight temperatures will be below freezing across much of the UK, falling to as low as -8C degrees in some parts of Scotland.
BBC weather presenter Rebecca Graham said the wintry showers will continue coming further inland, into the East Midlands, the South East and Kent.
"There will be a mix of snow and sleet, chopping and changing between the two," she added.
She said icy roads may be a problem where gritters had not managed to be out.
In Scotland, snow and ice caused road accidents and school closures, while a number of higher routes were closed.
Unusually, snow also blanketed beaches on the east coast, creating picturesque scenes.
But a light dusting in London – which caused "snowwatch" to trend on social media – led some to wonder what all the fuss was about.
It’s snowing in London!!!! Today is a goood day
