More snow is forecast for Northern Ireland, with temperatures set to dip as low as minus 4 celsius overnight.
On Saturday night, police advised motorists to avoid Rocky Road and Middle Braniel Road in the Castlereagh area due to treacherous conditions.
BBC Northern Ireland weather forecaster Angie Philips said sleet and snow were likely in the west on Sunday morning.
"Snow will spread across all parts on Sunday morning, with variations from place to place," she said.
"Some low lying areas and coasts may have a wintry mix of rain, sleet and wet snow, while inland areas will probably see around 3 or 4 hours worth of snow, giving a few centimetres, more of it the higher up you are."
Frozen pitches saw several Irish League football matches called off on Saturday.
Snow on Thursday and Friday saw many schools close, mostly in the Greater Belfast area and counties Down and Armagh.
While the snow was a break for some schoolchildren Environment Minister Sammy Wilson said too many people were using the weather as an excuse to take time off work.
He criticised "health and safety nuts" for mollycoddling people and also said parents should take more responsibility for getting their children to school.
The Irish National Teachers' Organisation said the minister was wrong to criticise the closures.
