However, Mr Dixon said some "marginally milder weather" would move in from the west at the weekend.

"Next week is looking like a period of some more settled weather with temperatures more around average."
While drivers and cyclists battled icy roads around Northern Ireland, pedestrians have found themselves also at risk of falls.

In west Belfast two men had to be rescued from a van that overturned on Divis Road this morning.
Aaron Kelly, from Ballymurphy, who was in the area with his father, Sammy, taking photos in the snow, said he heard a "tumbling" as the van went off the road.
"Me and my dad ran over to help them," he said.
"Two fellas going to finish a job. They went into a ditch, on its roof. My dad opened the door, they were upside down.
"They were all good thank good. They were definitely shocked".
Mr Kelly advised motorists to "drive slow" as you "never know what way your brakes are going to react".
Raymond Barr, an independent councillor on Derry City and Strabane District Council, spoke to BBC Radio Foyle about his commute early this morning from Strabane to Derry.
"It is passable but dangerous in parts, but secondary roads are treacherous."
