Forecasters say the current wintry weather is set to continue with a yellow warning now in place until 10am on Friday (January 20). However, the region covered by the warning has been reduced with the north and eastern parts of Northern Ireland affected.
The latest warning comes as freezing conditions and wintry showers continue to cause disruption to travel and force schools to close.
Forecasters are warning the public that with the potential for ice developing, there will be “some challenging travelling conditions” on Thursday night and Friday morning.
They say today (Thursday) will see a few wintry showers this morning, especially across the north and west. Otherwise it will be a mostly dry and cold day with some good spells of sunshine. The maximum temperature will be 4 °C.
There is a chance of a few showers in northern parts this evening, followed by a dry and clear night with a widespread sharp frost. A few freezing fog patches is also likely and a minimum temperature of -5 °C.
The Met Office says Friday will be dry and cold with plenty of sunshine, with freezing fog patches clearing by afternoon. The maximum temperature will be 4 °C.
It looks like it will be Saturday before a change sets in. Forecasters predict the weekend weather to be cloudy with a little rain at times and gradually becoming milder than of late.
Meanwhile, road users are advised to exercise caution when travelling, particularly when driving on untreated roads.
Police have warned motorists that driving conditions remain hazardous.
"If driving, motorists are reminded to proceed carefully and at lower speeds bearing in mind the impact of this weather on stopping distances and braking,” a spokesperson said.
