Ireland is experiencing "topsy-turvy weather" with temperatures swaying from the teens to almost freezing as we approach Christmas.
But it's still too early to say if Ireland will be hit by a snow storm on Christmas night, a Met Eireann forecaster said.
Joan Blackburn was responding to some online weather forecasts that suggest European weather models are pointing to a possible significant change in the weather on Christmas night and into St Stephen's Day.
"There are some indications in that direction but it is far too early to say," said Ms Blackburn.
"We are experiencing some topsy-turvy weather at the moment, with cold weather one day and much milder weather the next.
Temperatures are very mild at the moment for this time of year - in the south of the country this afternoon, she said they could reach as high as 12C or 13C.
Forecasters AccuWeather predict that a series of fast-moving storm systems will continue the unsettled weather from Ireland and Britain through northern Europe into this weekend.
High pressure over the eastern Atlantic will cause storms to pass south of Iceland then dive southward across Britain and into parts of northern Europe, such as Netherlands, Belgium and Germany.
However, the storms will not be strong enough to cause widespread damage or travel disruption.
Met Eireann is predicting a cold, blustery day tomorrow with temperatures of six to nine degrees.
However, it will feel colder thanks to strong westerly winds gusting to gale force producing a "considerable wind chill".
Saturday will be slightly warmer with temperatures peaking at seven to 10 degrees and a slight ground frost in sheltered rural areas.
It will be windy on Sunday and Monday, but much milder with daytime temperatures of up to 10 or 13 degrees.
Leinster and Munster will be largely dry, however Connacht and Ulster can expect frequent rain showers - some heavy.
Peter O'Donnell from Irish Weather Online said it was too early to predict Christmas snow storms - but that things should be clearer by this weekend.
"The leading European model has made a dramatic shift towards extreme winter conditions on its maps for the period late Christmas Day to December 27 and beyond," he said.
"It is too early to be definitive but we all need to be on high alert if this trend continues."
However, the uncertainty hasn't stopped bookmaker Paddy Power offering odds of 7/2 of Dublin having a white Christmas and odds of 4/1 for Cork to have snow on Christmas Day.
