Ireland is set to see temperatures plunge below freezing on multiple nights this week, with the potential for 'wintry showers' for the start of December over the weekend.

Although Sunday was a mild night, there have been frosty conditions in recent days as temperatures have steadily dropped from the low to mid-teens down to single figures.
