The spell of cold weather will continue well into next week, forecasts show.
Cathal Nolan of the Weather Channel said that there was no sign yet of a thaw.
"As we look forward to the evening and again to tonight, we can expect those temperatures really plummet, dropping back to -6, maybe -7, under clear skies in some places," he told Newstalk.
Temperatures fell to as low as -6 degrees overnight.
The national forecaster had issued a status yellow freeing fog and ice warning for the entire country and a yellow snow warning for Dublin, Kildare and Wicklow.
