There will be widespread wintry showers with a continued risk of hail and thunder. The snowfall will lead to a risk of ice and tricky road conditions.

Further falls of snow leading to icy stretches on roads and paths and some accumulations, especially in Connacht and Ulster.

Minimum temperatures of -2 to +2 degrees in fresh southwest to west breezes with an extensive frost.
