There is a "bitterly cold week ahead", says Carlow forecaster, Alan O'Reilly.
Weather charts also show a risk of some sleet and snow Wednesday night.
According to www.carlowweather.com, there will be low wind chill each day and a risk of wintry showers on Wednesday night, especially on higher ground.
Alan said: "Very marginal setup with high ground more at risk but one to keep an eye on as some could wake to a white Thursday morning.
"Might be time to get the long johns out!"
