Jack Frost won't be around for long - as milder temperatures look set to return by tomorrow.
The frost and fog of recent days will gradually clear tomorrow morning and make way for sunshine and higher temperatures.
An unseasonably mild winter so far, the warm temperatures will continue to reach highs of nine degrees in some parts of the country for the rest of the week.
And, although temperatures on Wednesday night could dip below zero, the nights are set to average seven degrees this week.
According to Met Eireann, southwest breezes could bring in some cloud and rain at times.
Outdoor plans can be made for the last weekend of the Christmas break, as the biggest threats forecast are some scattered patches of drizzle and mist.
It will be cloudy on Saturday and Sunday but dry and bright spells are also expected, especially on Sunday.
Top temperatures for the weekend will be nine to 12 degrees.
