Met Éireann says there will be hazardous conditions due to a widespread severe frost, leading to ice on untreated surfaces.
Wednesday night will be largely dry with clear spells - but some areas may see isolated spots of sleet and snow.
It will be cold with lowest temperatures of -3 to +3°.
Hazardous conditions can be expected due to a widespread severe frost away from eastern fringes, with ice on untreated surfaces "leading to treacherous conditions."
There will also be some pockets of dense or freezing fog.
Any frost, ice and fog will clear early on Thursday to leave a largely dry and bright morning with sunny spells.
