Temperatures as low as -4C expected

Speaking on RTÉ's Morning Ireland, Met Éireann senior forecaster Gerry Murphy said the cold weather will continue today with another frosty night in store and temperatures are expected to reach as low as -4C.

"As we go into tomorrow, we will see milder air with a band of rain moving in from the southwest, but because it is going to meet that very cold air as it pushes up across the country through tomorrow evening, tomorrow night into Sunday, it is going to turn to sleet and snow in many areas."

Mr Murphy said as the forecaster gets more "more details on the exact accumulations of that snow, it will give us more information on the exact types of warnings that we will be issuing today and tomorrow."

Regarding possible school closures because of the snow, he said that will not become clear until over the weekend.
