A status yellow low temperature-ice warning is in place for the entire country until eleven o clock this morning.
It'll lead to difficult travelling conditions, with the cold snap set to last for the week.
Alan O'Reilly from Carlow Weather says there's a risk of snow in the northwest of the country.
'There will be some wintry showers in the north and the north west, falling as sleet and snow, especially snow on higher ground but there is a risk of some snow falling on lower ground, but it really won't make it that far further south so it really is the north and the north west at rick of seeing those wintry showers.'
