National Outlook
Overview: High pressure will bring mainly dry and settled conditions throughout the Christmas period and continuing into the New Year. Rather cold with an easterly airflow and with some frost by night, though eastern coastal parts are likely to remain frost free during the Christmas period and over the weekend due to the onshore breeze.
Christmas Eve (Wednesday) night: Santa and his reindeer will have very favourable conditions for their trip around Ireland on Christmas Eve night. It's going to be a dry night with long clear spells. Lowest temperatures of -1 to +5 degrees, coldest across the midlands and west, with some frost forming away from eastern coasts, in mostly light to moderate easterly or variable breezes.
Christmas Day (Thursday): Frost will clear to leave a dry, bright day with a mix of cloud and plenty of sunshine for most. Rather cold, with highest temperatures of 4 to 8 degrees and feeling colder, especially along the east and south coast with fresh and gusty easterly winds there, otherwise easterly winds will be mostly moderate.
Christmas night (Thursday night): It'll be a dry, cold and mostly clear night with frost forming away from eastern coasts. Lowest temperatures of -3 to +1 degrees generally, though a little higher in eastern parts, ranging from 2 to 6 degrees. Easterly winds will generally decrease light to moderate, though will be a little fresher for a time along eastern and southern coasts.
St. Stephen's Day (Friday): Another dry day with variable amounts of cloud and good sunny spells are likely once again. Highest temperatures of 4 to 8 degrees and it'll become a bit breezier with northeasterly winds increasing mostly moderate, and will be fresh and occasionally gusty along the east coast.
St. Stephen's (Friday) night: Dry and cold with a mix of cloud and clear spells. Lowest temperatures of -1 to 4 degrees generally, though less cold in eastern parts. Winds will be mostly moderate northeasterly, but fresher in eastern and some southern coastal parts. There'll be some patchy frost in sheltered parts, but it'll remain frost free where its breeziest along eastern and southern coastal parts.
Next weekend:
It'll continue cold and dry with variable cloud and spells of sunshine. It'll be breezy enough on Saturday with moderate to fresh easterly winds. There'll be some frost in sheltered parts on Saturday night. Winds will probably ease light to moderate on Sunday, with the likelihood of more in the way of frost forming on Sunday night where skies remain clear. Those lighter winds on Sunday night mean some fog or freezing fog will form too.
Further outlook:
High pressure will continue to dominate next week in the lead up to the New Year and probably beyond into next weekend. So the dry cold conditions will prevail, with variable cloud cover and some sunny spells. The centre of the area of high pressure will move close to or over Ireland, which means winds will be lighter, but that means under clearer skies frost will be more widespread, with the added hazard of fog and freezing fog too, which will could be slow to clear by day.
