TODAY - Saturday 20th December

Breezy or blustery in most places this afternoon, with outbreaks of rain, heavy at times, extending northeastwards over the country. Fresh to strong and gusty south to southeast winds, with gales on coasts. Rain will clear from the west and southwest this afternoon, with scattered showers and light winds following there, but wet and blustery conditions will persist further east and north with spot flooding possible in the southeast. Highest temperatures 7 to 10 degrees.

TONIGHT

Breezy conditions with outbreaks of rain and drizzle across parts of the midlands, east and north at first tonight, calmer with clear breaks and scattered showers elsewhere. The rain will gradually ease and become patchy overnight and some showers may turn wintry over hills in parts of the west and southwest. Lowest temperatures of -1 to +6 degrees, coldest in Munster where skies will be clearest. Winds will be mainly light southeast or variable across Munster and Connacht, but fresh to strong and gusty southeast at first elsewhere, before gradually easing overnight.

TOMORROW - Sunday 21st December

A chilly start for some on Sunday, with variable cloud and sunny spells and just well scattered showers to begin. Some longer spells of rain will spread up from the southeast in the afternoon and extend northwestwards. Afternoon highs of 5 to 9 degrees in light easterly or variable breezes.

National Outlook

Overview: While there is a little uncertainty in the exact details over the next few days, conditions are likely to become more settled as high pressure moves in bringing mostly dry and calm weather throughout the Christmas period, cooler at times too.

Sunday night: Mostly cloudy with patchy outbreaks of rain and drizzle gradually easing overnight. Lowest temperatures of 3 to 8 degrees for Ulster, Leinster; -1 to +3 for Munster and Connacht, in light easterly or variable breezes. Mist and fog patches too with slight chance of frost and ice forming where clear breaks occur.

Monday: Mostly cloudy and misty with patchy rain and drizzle. More persistent spells of rain will affect the east and north. Highest temperatures of 5 to 9 degrees, in just a light easterly breeze.

Monday night: Mostly cloudy with patchy rain and drizzle and occasional clearer breaks, mainly near western coasts. Mist and fog patches too. Lowest temperatures of -1 to +4 degrees, coldest in the southwest in light southerly or variable winds.

Tuesday: Still some uncertainty in the details for Tuesday but it looks like it'll be cloudy to begin with patchy rain, drizzle and mist, giving way to a mix of sunny spells and showers from the west in the afternoon. Highest temperature of 5 to 9 degrees with just light variable breezes. Mist and fog places also.

Current indications for Christmas Eve and Christmas Day suggest it'll be rather cold and dry with a mix of cloud and crisp sunny spells. Frost and ice will form in places to begin and end each day. Coastal showers will move up along the East coast, but will be isolated, in light to moderate east to northeast breezes.
