Yorkshire woke to another frosty morning on Saturday after temperatures plunged below freezing.
And it's going to be a similar picture tomorrow morning as thermometers have struggled to have readings much over 0C today.
Temperatures could fall as low as -4C in Yorkshire tonight, making another widespread frost likely.
A Met Office weather warning is in place for Sunday, stating: "Icy patches will be a hazard on some untreated roads, pavements and cycle paths. Some injuries are possible from slips and falls on icy surfaces."
A milder front is on the way and Sunday daytime could see highs of 9C with occasional rain showers also arriving.
Met Office forecaster Greg Dewhurst said: "There's another cold night to come, and Sunday into Monday - perhaps even Monday into Tuesday too - but eventually we will see some milder conditions with temperatures reaching double figures."
So is a white Christmas a possibility still?
"It's still a little bit too early to say, but generally it looks like a milder, breezy and wet theme," added Mr Dewhurst.
"There are hints that there could be a few colder bits coming through - but nothing like what we've seen."
