Outbreaks of rain will develop in the east and north on Friday morning, with the potential for heavy and prolonged falls leading to localised flooding, Met Éireann has warned.
The rain will be patchier elsewhere at first, but will turn more persistent later in the day. It will turn cooler across the north of the country, with highs of 10°C to 12°C, and afternoon temperatures ranging from 13°C to 15°C elsewhere.
There will be strong northwest winds along the southwest coast, but moderate to fresh northeast winds in other areas.
Patchy rain in the south is likely to clear during Saturday morning to leave a day of sunny spells and passing showers.
Maximum temperatures of 10°C to 13°C in a moderate northwesterly breeze.
Clear spells and just isolated showers on Saturday night. Rather cold, with some mist or fog patches forming. Lowest temperatures of 4°C to 7°C, with mostly light westerly breezes.
It looks set to be mostly dry on Sunday, with plenty of autumnal sunshine and just the odd passing shower, according to Met Éireann. Highest temperatures of 11°C to 14°C in light, variable winds.
Many areas are expected to be dry on Sunday night, but there is the chance of some patchy rain in the south later. A chilly night for many, with lowest temperatures of 2°C to 6°C, but milder in southern coastal counties.
