The alert - urging the public to take extra care, especially when travelling - comes as temperatures look set to plummet elsewhere in the UK.
Raw easterly winds are being pushed in by a high pressure system over Scandinavia and western Russia, meaning that the mercury could fall as low as minus 10 degrees in places.
While it will be cold in Northern Ireland, daytime temperatures are expected to stay in single figures - but certainly above freezing - with night-time figures perhaps dipping to around minus 2 degrees.
It's a picture that is forecast to stay in place throughout the week and into the weekend, with frost, freezing fog and hill snow possible at times.
But the worst of the Arctic-influenced cold snap seems reserved for Wales and the west of England, with a cold weather amber alert (the Met Office's second most serious warning) in place.
