Showers of hail, sleet and snow are expected to clear by Sunday, Met Éireann said today.
However the rest of the week will see continued wintry showers - especially this evening and tomorrow.
"There may be some freezing fog at night as temperatures drop and the next few nights in general are expected to be cold and frosty, mainly in Leinster, east Munster and east Ulster," a Met spokeswoman said.
"On Saturday, showers will be very much diminished, while on Sunday most places will be dry - match conditions should be dry and clear" the spokeswoman added. The Ireland rugby team is playing England in Lansdowne Road on Sunday.
Leinster has been worst affected by the cold spell in recent days, with the west and south-west getting mainly dry clear conditions including sunshine during the day but some frost at night.
AA Roadwatch says driving conditions have improved since earlier this morning, although it is still snowing in some parts of the midlands. Motorists should drive with extra care in Kildare, Offaly, Laois and Westmeath.
In Wicklow the Sally Gap is likely to remain closed for the rest of the week due to poor conditions. Irish Ferries Swift sailings are suspended until Sunday, February 27th, for essential maintenance but all other Irish Ferries and Stena Line sailings are running to schedule.
Weather aside, motorists on the N2 should note that traffic will be reduced to one lane just south of Kilshane Cross today and tomorrow due to the construction of a bridge.
