Overview.

Leinster

Today

Windy today, Wednesday, with strong to gale force southwesterly winds, accompanied by severe and potentially damaging gusts, especially later this morning and early this afternoon, associated with Storm Ali. Rain this morning clearing by this afternoon, and brightening up with a few sunny spells occurring, and just the odd isolated shower. Winds will ease later in the day. Maximum temperatures of 14 to 17 degrees.

Tonight

Mostly dry tonight, but there is a risk of some patchy rain and drizzle in southeastern parts of the province. Southwesterly winds will continue to moderate overnight, becoming light and variable in the south. A chilly night, with lows of 6 to 9 degrees.

Tomorrow

Dry in many parts at first tomorrow, Thursday, with the best of any sunshine further north during the morning. Mostly cloudy further south, with outbreaks of rain spreading from the south during the morning and affecting much of the province through the afternoon and evening. The rain will be heavy and persistent, especially over south Leinster where there is a risk of spot flooding. Winds mainly light and variable, becoming moderate to fresh north to northwest in the evening. Top temperatures just 11 to 14 degrees.

National

Today

Storm Ali will bring very windy conditions to all areas today with strong to gale force south to southwest winds later veering westerly. There will be severe or possibly damaging gusts for a time this morning especially in the west and northwest. Extreme caution is advised in the coastal districts of Clare, Connacht and Donegal this morning with Strong Gale and storm force winds here. Squally showery rain will affect many areas at first, with heavy bursts in places. The rain will clear quickly eastwards, later this morning however, with sunshine and blustery showers following behind for the afternoon. Turning cooler, with afternoon temperatures of 14 to 17 degrees. Winds will ease somewhat through the afternoon but remain strong in many areas.

Tonight

Many places will be dry tonight, aside from a scattering of showers affecting western and northern areas, and patchy rain and drizzle along southern coasts. Southwesterly winds will continue to moderate overnight, becoming light and variable over southern counties. A chilly night, with lows of 6 to 9 degrees.

Tomorrow

Dry in many areas at first tomorrow, Thursday, with the best of any sunshine further north during the morning. Mostly cloudy further south, with outbreaks of rain spreading from the south and affecting much of the country through the afternoon and evening. The rain will be heavy and persistent in Munster and south Leinster, with a risk of spot flooding, but tending more intermittent in nature elsewhere. Winds mainly light and variable, becoming moderate to fresh north to northwest in the evening. Top temperatures just 11 to 14 degrees.

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.
