The Met Office has put a yellow weather warning in place for Northern Ireland over the next two days.
A yellow warning will come into effect from 3pm on Wednesday, December 14 and end at 11am tomorrow, December 15. The warning is for "wintry showers and ice".
A Met Office spokesperson said: "Occasional wintry showers will lead to ice forming on untreated surfaces. The showers mainly of rain or sleet around the north coast throughout, and on the east coast on Thursday morning, but otherwise falling as snow with accumulations of 1 to 3 cm in a few places."

Last week, the Department for Infrastructure said it has around 300 staff and 130 gritters available to salt main roads, with 12 specialist snow blowers also available to be deployed if required.
Colin Sykes, Director of Road Asset Maintenance, said: "Every year our winter service operation remains in place from October to April to ensure 7,000 kilometres of the road network on the salting schedule remain open.
"With snow and ice forecast for this week and some disruption on our roads possible, staff are ready to be deployed as necessary.
"We have around 74,000 tonnes of salt in stock and in addition over 5,500 salt bins and 58,000 grit piles are also available for use by the public on a self-help basis on selected routes not included on the salting schedule.
"Despite our best efforts it is important to remember that we cannot guarantee ice-free roads even after salting. We all need to be mindful of the changing conditions and adjust the way we drive, ride or cycle to ensure it is appropriate for the conditions.
"The best advice is in the Highway Code, take extra care even if roads have been salted, be prepared for road conditions changing over short distances and take care when overtaking gritters."
