Many regions are still expected to see snow today after being blanketed this week following the coldest night of the year.
Last night's night temperatures were similar to Wednesday, which was the coldest night of the year before even colder conditions move in on Friday night.
Met Office meteorologist Alex Burkill said that areas of the Highlands could see minus 17C, after this year's record low of minus 16C was recorded at Altnaharra in the region.
It comes as Storm Larisa, which was named by the French weather service, is going to batter the UK today.
Met Office meteorologist Jonathan Vautrey said: "Storm Larisa, which Meteo France has named, is the same low-pressure system that is bringing us the bands of rain.

"But essentially, we're on the northern side of the low-pressure system and it's the southern side of that low-pressure system that is going to be bringing particularly strong winds to parts of France.
"So that did originate out in the Atlantic and then it tracked its way eastward towards us, and the weather fronts that are swirling around that low-pressure system have then been pushing into the cold air that has been in places across the UK and allowing that rain to start falling as snow across several areas."
The weather is expected to clear by the end of Friday, before then being replaced by another low-pressure system, leading to further yellow snow and ice warning for much of northern England and Scotland from 3pm on Saturday to 6am on Sunday.
