Temperatures to hit -5C as Arctic snap drifts in
The first cold blast of the winter is set to bring sub-zero temperatures to all parts of the country this week, with hail, sleet and even snow in some areas.
But while Met Eireann warned that ground temperatures could drop to minus 5C later this week, it should remain sunny, clear and bright in most areas.
"There is certainly a cold snap on the way. Our forecast models have been tracking it for the past few days," Met Eireann forecaster Evelyn Cusack said. "The weather is coming down from Scandinavia and during the week the airflow will be more northerly so it will come directly from Arctic regions."
This arctic airflow is set to keep temperatures at a chilly 4C to 8C during the daytime, while at night clear skies will cause temperatures to dip to as low as minus 5C.
Later in the week, parts of Donegal and Mayo could be hit by wintry showers of hail, sleet and even snow in high areas.
