With sub-zero temperatures and heavy snowfall predicted to last until the end of the month, it could turn out to be one of the coldest periods in this country for a number of years.
James Madden, forecaster with Exacta Weather, said the prolonged bitter weather was likely to stretch into February, with mercury levels at times dropping to double-negative figures.
He said: “There is likely to be some significant changes throughout the second half of January to some prolonged cold spells and a number of widespread snow events across large parts of Northern Ireland. It may even arrive a little earlier than mid-month.
