National Outlook

OUTLOOK: Settled and relatively mild up to and including much of Sunday however there will be some patchy drizzle about at times. Becoming more unsettled from Sunday evening onwards with wet and blustery conditions at times.

THURSDAY NIGHT: Most areas will be dry with clear spells early on Thursday night. However, cloud will build in form the west and will extend across the country overnight. This will bring outbreaks of rain to northern and western coastal regions, but remaining dry elsewhere. Lowest temperatures of 9 to 14 degrees, coolest in the midlands. As southwest winds fall light to moderate in most areas some patchy mist and fog patches will develop once again.

FRIDAY: Friday will be largely cloudy with scattered outbreaks of light rain or drizzle, mainly in northern and western areas. The best of any sunny spells will likely develop near southern and southeastern coasts during the afternoon. This is also where temperatures will be highest, reaching up to 21 or 22 degrees, cooler elsewhere though with highs ranging from 16 to 19 degrees, holding coolest in the northwest. The winds will be mostly moderate however they will be fresh at times in Ulster but falling light along southern coasts.

FRIDAY NIGHT: The scattered light rain and drizzle will continue for a time in northern areas on Friday night, however it will remain largely dry elsewhere with a mix of cloud and clear spells. Some mist and fog patches will develop once again as winds back southerly or variable and fall mostly light. Holding mild though with lowest temperatures not falling below 11 to 15 degrees.

SATURDAY: Mostly dry and cloudy to start Saturday, patchy rain will develop over Munster and south Leinster before extending northwards during the afternoon as some bright or sunny spells develop behind the rain. A milder day for many with temperatures widely reaching 18 to 20 degrees, in light south to southeast breezes.

SATURDAY NIGHT: Saturday night will be mostly dry with good clear spells but a light shower can't be ruled out. Some mist patches early in the night but the light to moderate southeasterly winds, will freshen in western areas towards morning. Lowest temperatures of 11 to 14 degrees.

SUNDAY: Sunday will be breezy, as fresh and gusty southeasterly winds develop. Sunny spells and showers at first, but a band of heavy showery rain will move in from the Atlantic during the evening. Highest temperatures of 17 to 20 degrees. The rain will quickly clear the east early in the night with blustery showers following from the west by morning. Lowest temperatures of 8 to 11 degrees in light to moderate southwesterly breezes.

FURTHER OUTLOOK: Early next week looks unsettled and cooler with Atlantic depressions expected to bring blustery showers on Monday, and further rain and breezy conditions on Tuesday and Wednesday.
