Yellow weather warning in place with temperatures set to hit -8C
More treacherous weather is expected overnight in Northern Ireland with a yellow warning in place from the Met Office.
The public are warned to be cautious through until midday on Sunday.
Wintry showers on Saturday are expected to become more confined to the far north of Scotland overnight, with Antrim, Londonderry, and Down also impacted.
Icy surfaces will prove an additional hazard, with untreated roads, pavements, and cycle paths expected to be impacted.
The public are advised to plan additional time for journeys, with road and bus services affected.
Widespread frost is expected overnight, with temperatures dipping as low as -8C in some places.
Belfast City and the City of Derry Airport have advised passengers to leave additional time for their journeys.
A number of Irish League matches were called off on Saturday due to the poor weather conditions.
The Met Office warned of wintry showers in the north with freezing temperatures reaching a maximum of only 4°C in what has been described as one of the coldest Decembers in recent years.
Met Office forecaster John Wylie indicated that Friday's temperatures were expected to dip to as low as -4°C inland, accompanied by a sharp frost.
He noted that such cold December temperatures have not been recorded in recent years.
"There has not been cold weather like this for a couple of years now. It is the first proper wintry spell, where there has been widespread snow, for the past two or three years."
While the snow caused excitement for many on Friday morning, it led to a major slow-down on the roads, reducing traffic to a crawl on some major routes.
Black ice under snow made roads dangerous with a number of vehicles losing control. There was report of a vehicle on its roof on the M2 yesterday morning.
Among the worst affected areas were Nutts Corner and Dundrod in Co Antrim where there were reports of lorries and cars spinning at Quarterland Road.
Four cars were involved in a collision at Donaghys Lane in Larne, near the junction with Antiville Road, around 8am, and an accident on the A26 Frosses road in north Antrim near Cloughmills resulted long tailbacks for Ballymena-bound traffic.
The Department of Infrastructure stated that salting of the scheduled road network would continue, with snow ploughs also in operation.
It has been reported that 300 staff and 130 gritters using 90,000 tonnes of salt will be available to "salt main roads to keep traffic moving safely and freely".
