The Public Weather Service advisor to Northern Ireland summed up the treacherous conditions as "a never-ending winter".
John Wylie also revealed that temperatures will hit as low as -5 degrees this week as the unseasonable big freeze continues to wreak havoc. "It's unusually cold for late March and it's going to stay very cold over the next few days," said Mr Wylie. "Temperatures by day will be no more than 4 or 5 degrees, but equally night time temperatures could be down to -4 or -5 degrees inland.
"A lot of the snow that is lying is not going to get a chance to melt, particularly on the high ground, but that in some respects is not a bad thing.
"There's so much of it that if it was to all melt very quickly there could be real problems, but that doesn't look like it will be the case and I think we can expect a gradual thaw out of snow."
Mr Wylie said there might be more snow showers, particularly in the eastern counties, but he added that a huge quantity of the white stuff is not expected.
"In comparison to what we have already had, the fresh snowfall won't be in the same league," he said, advising people to wrap up.

Nick Prebble, a forecaster for MeteoGroup, the weather division for the Press Association, said the cold weather was expected to last for at least a few more days, although there will be a respite from the heavy snowfalls.
He said: "The cold and dry weather will stay with us and it will be a similar picture for the next three days. Temperatures are going to struggle, generally reaching 2-3C (35.6-37.4F).
"It will feel even colder though, because of the easterly breeze bringing in colder air."
