Met Éireann says it's looking unlikely we'll see a white Christmas.
A tropical airflow has caused temperatures to rise significantly today, following last week's cold snap.
An arctic air mass resulted in overnight lows of -8 and -9 degrees recorded on Wednesday and Thursday last week.
Temperatures are expected to fall back to average December values of 7 or 9 degrees again later this week.
Michelle Dillon, Meteorologist with Met Éireann, says although they're still not sure about Sunday's weather, it doesn't look like it's going to snow.
"At the moment it looks like staying on more average temperatures, with some wet and some windy weather."
"So at the moment, it doesn't look like it will be a white Christmas, but there's some uncertainty in that."
"There could be a chance of a few wintry flurries straight after Christmas, maybe into in Stephen's Day, especially in northern parts."
