Hail, sleet and snow are on the cards after Met Éireann predicted a cold snap next week.
The national forecaster said it will become noticeably colder from Wednesday onwards with a northerly airflow and with showers possibly turning more wintry at times.
This weekend average daytime temperatures will drop to as low as 5 degrees Celsius, with mostly dry conditions forecast for the coming days.
Some bookmakers have slashed their odds on a White Christmas.
However, Met Eireann have said it is much too early to speculate on weather patterns for more than three weeks in advance.
