Met Eireann is expecting snow on Saturday, Sunday and Monday as chilly weather arrives again.
The national forecaster said that it's "going to feel much colder by the time we get to Saturday" as more freezing conditions hit our shores.
The northern half of the country is expected to get the worst of the weather, with a higher likelihood of snow.
However, forecasters aren't currently predicting widespread heavy falls in the next few days.
A Met Eireann forecaster said: "Saturday morning will be cold and windy. It will be mainly dry in Ulster, however rain will continue elsewhere, falling as sleet or snow at times, especially in Leinster.
"It will gradually clear southwards through the afternoon and early evening. Highest temperatures of 3 to 6 degrees with fresh, gusty easterly winds.
"Saturday night will be cold and mainly dry with clear spells and a sharp frost as temperatures fall to between -1 and +2 degrees. Rain and sleet will develop in the west overnight.
"On Sunday morning rain and sleet will spread eastwards across the country, falling as snow in places, especially over the northern half of the country.
"The rain and sleet will continue for the rest of the day and throughout Sunday night, with snow possible in Ulster. Highest daytime temperatures of 1 to 4 degrees for most areas and reaching 6 or 7 in Munster with moderate to fresh easterly winds.
"They will fall to between 0 and 6 degrees on Sunday night, coldest in Ulster."
The cold weather will continue into Monday, although forecasters aren't expecting snow on Tuesday.
A spokesman added: "Monday will be cold and mostly cloudy with further falls of rain and sleet, with snow possible in northern areas. Highest afternoon temperatures of 2 to 7 degrees, coldest in Ulster with moderate southeast winds, becoming southerly and freshening.
"A band of rain will spread northeastwards throughout the evening and night, and will clear overnight with showers following. Lowest temperatures of 3 to 7 degrees with moderate to fresh southeast winds."
