Daytime temperatures this Friday could be as low as three to six degrees in much of the country.
Met forecasters warn, though, that where fog persists in daytime this weekend the temperatures will hover near zero.
There are weather warnings of ice in this region tonight, Friday.
Says Met: ''Friday night will be very cold with a widespread sharp or severe frost with ice in places and patches of freezing fog.
''Lowest temperatures,'' adds Met, ''of minus five to zero degrees, coldest in Connacht and Ulster.''
The outlook up to Tuesday is mainly dry and cold, warmer temperatures in this region with frost at night.
The current spell is due to the High Pressure area dominating our weather charts.
