Met Eireann has warned that temperatures will drop to -2 tonight, as bitter and frosty conditions will continue through the rest of the week.
The forecast says: “Tonight will be dry with long clear spells and just the chance of a light shower in the northwest. Lowest temperatures of -2 to +3 degrees generally.
“Frost and mist patches will form in mostly light southwesterly or variable breezes.”
The cold weather shows no signs of reversing with widespread frost and fog is expected to form by night and the fog will be persistent in places during the day.
Despite this, there are brighter days ahead, with continuing settled and largely dry through the rest of the week as high pressure dominates our weather.
Weather expert, Alan O'Reilly from Carlow Weather shared on Twitter: “A cool morning in the Northwest but a good day ahead once any cloud and light rain clears the South.”
