Brutal June Bank Holiday weather forecast as Met Éireann warns of 'Atlantic regime'

Met Éireann has warned a 'mobile Atlantic regime' looks set to bring further unsettled weather to Ireland for the rest of this week, into the June Bank Holiday weekend and beyond. 

Their forecasters have said "a mobile Atlantic regime dominates bringing mixed and changeable conditions" as they delivered a brutal forecast for the coming days.

In their outlook for the rest of the week, Met Éireann say: "Wednesday will bring a good deal of cloud but some bright or sunny breaks too, along with scattered showers. Cloud will thicken from the southwest this afternoon, and outbreaks of rain will extend northeastwards over the country this evening. Highest temperatures of 14 to 18 degrees with light to moderate westerly winds, becoming southerly this evening.

"Mild tonight [Wednesday], and becoming rather breezy or windy with further spells of rain and drizzle. The rain will be heaviest and most persistent in parts of the west and north overnight, with lighter and patchier falls elsewhere. Lowest temperatures of 10 to 13 degrees with south to southwest winds increasing moderate to fresh and gusty, strong near coasts.

"Windy, damp and cloudy, Thursday, with patchy outbreaks of rain and drizzle, heavy for a time early on in the north and northwest. Some temporary bright or sunny spells will occur during the afternoon, mainly across parts of the north and east. Fresh to strong and gusty southwest to west winds will ease somewhat through the day. Mild and humid, with highest temperatures of 15 to 20 degrees.

"Mostly cloudy with outbreaks of rain and drizzle, heavy at times [on Thursday night], becoming increasingly confined to the south and southeast as clearer breaks develop further north and west towards morning. Lowest temperatures of 10 to 15 degrees coolest in the north with mostly moderate southwesterly winds fresh to strong and gusty in northwestern coastal fringes."

The forecast continues: "Friday will be a largely dry day for many with variable cloud and sunshine. Any residual rain and drizzle in the south and southeast will soon clear in the morning, with just well scattered showers following for the rest of the day. Highest temperatures of 16 to 21 degrees.

"Moderate southwest to west winds, initially fresh to strong near the northwest coast, will ease light to moderate as the day goes on. A mix of cloud and clear spells on Friday night with a few mist patches forming around dawn. Lowest temperatures 9 to 13 degrees with light southerly breezes, increasing moderate towards morning.

"Mainly dry and bright to begin on Saturday, but a spell of rain, possibly heavy, will soon spread from the west through the morning and afternoon. The rain will clear into the Irish Sea in the afternoon, and will be followed by sunshine and showers, some heavy in the northwest, with the chance of thunder. Highest temperatures of 15 to 20 degrees in moderate to fresh southwest winds, but becoming very windy later near Atlantic coasts, with strong to gale force and gusty southwest winds developing in the evening.

"Breezy on Sunday with a mix of sunshine and showers, some heavy and possibly thundery. Temperatures will be a little lower than the previous couple of days with highest values of 13 to 17 degrees and it'll be breezy or rather windy with moderate to fresh and gusty westerly winds, strong at times near coasts.

"Current indications suggest a mainly dry and bright start with just a few showers in the mix [for Bank Holiday Monday], but tending to cloud over later with rain spreading from the Atlantic later in the day. Highest temperatures 14 to 17 degrees. Light to moderate southwest winds will increase moderate to fresh southerly in the evening."

Met Éireann's further outlook beyond that is for more "changeable and unsettled" weather.
