National Outlook

Remaining unsettled for the rest of this week, with strong winds and heavy rain at times. Settling down next week.

Thursday night: The rain will gradually ease and clear out eastwards on Thursday night, and most places will become dry with long clear spells developing. Scattered showers will start to affect Atlantic coastal counties later in the night. Light to moderate northwesterly winds backing westerly overnight and increasing fresh to strong and gusty near coasts. Another chilly night with minimum temperatures of just 5 to 8 degrees.

Friday: Cool, bright and breezy with sunny spells and scattered showers for Friday. Moderate to fresh and gusty west to northwest winds, strong to near gale along coasts, will ease towards evening and the showers will become increasingly isolated. Highs of 12 to 15 degrees.
Most places dry on Friday night with variable cloud and clear spells. Light to moderate southwesterly winds on Friday night with lows of 5 to 8 degrees.

Saturday: Present charts indicate a mainly dry start to Saturday, but with rain and strong winds moving in off the Atlantic and extending northeastwards over the country during the day, although the timing of the rain and stronger winds may yet alter. Winds mainly light to moderate southwesterly at first, becoming southeasterly during the afternoon and freshening in the west and south. Top temperatures 11 to 15 degrees, warmest in the south.

Sunday: Marked uncertainty still for Sunday, but current indications suggest a wet and windy start to the day, improving later. Milder than recent days.

Early next week: Drier, more settled conditions are signalled with high pressure likely to be the dominant feature. Good sunshine by day, but with a risk of night-time mist and fog lingering for a time in the mornings. Daytime temperatures rather cool at first, but possibly improving to nearer average later.
