A bright start is expected this morning following a day of snow showers and a yellow warning of icy conditions overnight.
The worst of the snow was in the north with the weather warning mainly affecting Co Antrim.
In Glengormley, the Upper Hightown Road was closed overnight on Thursday due to snowfall but was reopened yesterday morning before the main rush-hour, while difficulties were also reported in Coleraine and coastal areas of Co Londonderry.
In many other areas there were showers of rain turning to sleet also making driving conditions hazardous.
This morning’s bright start, with top a temperature of a chilly 3C, will continue in most areas up until mid-afternoon when it will begin to cloud over and temperatures could rise to 5C.
Light showers of rain are expected to be widespread across Northern Ireland during the early evening.
There will be a cloudy start to tomorrow with the showers expected to return by lunchtime and continue through the early afternoon.
As the cloud begins to clear on Sunday night the temperatures could fall to 4C overnight.
Monday and Tuesday are going to be similar with light rain in most areas and top daytime temperatures of 8C.
A spokesman for Meteogroup, the weather forecasting arm of the Press Association, said tomorrow would bring “an unsettled and wet” morning.
“There will be outbreaks or rain but during the afternoon the rain should clear and leave variable cloud and showers.”
The spokesman added: “Sunday will be cold but overnight when the rain and clouds come in it will stop things getting to zero. In England where that rain is not coming in then it will be a very cold night.”
In many English regions specialist response crews have been deployed – including chainsaw teams and railway maintenance staff.
