No let-up as the big chill to stay for week
Cold wintry conditions will continue to grip the country for the next week as sub-zero temperatures show no signs of abating.
Parts of Co Donegal were covered in up to three inches of snow yesterday following showers on Friday and Saturday.
Snow also lingered on the Dublin and Wicklow mountains yesterday and motorists were being warned last night to avoid the Sally Gap in Co Wicklow.
In the west, thick fog added to icy road problems for motorists yesterday and forced the closure of Knock airport.
Wintry conditions will continue to dominate for much of this week, with overnight temperatures dipping down to between 0C and -5C, according to Met Eireann.
Extremely cold conditions that are well below normal will remain, with daytime temperatures reaching just 4C to 6C with severe frost and fog patches expected in some areas overnight for much of the coming week, according to meteorologist Pat Clarke.
Rain is expected in southern areas by tomorrow morning and will spread across much of the country by the afternoon.
Rain and sleet forecast for the south of England tomorrow could also lead to sleet and snow showers across much of Ireland.
More wintry showers are also forecast for early Wednesday morning. Thursday is expected to be dry with sunny spells.
But despite clear skies, temperatures are not expected to climb, Mr Clarke said. "It should be four to five degrees warmer than it is now," he said.
"There's no sign of milder weather until the end of the month," he added.
