Met Éireann pinpoint day for ‘high pressure’ weather for Ireland but there’s a catch

Met Éireann is predicting a return of high pressure to Ireland this year, bringing a welcome upturn in our weather fortunes with mild temperatures and drier days.

It looks as though the high pressure will build later in the week and next weekend but we may have to endure some more cloud, rain and drizzle between now and then.

The high pressure reprise also looks like it may be short-lived with Met Éireann’s extended range forecasting predicting a brutal change in early November.

The Met Éireann forecast for Sunday says: “Turning cloudier as outbreaks of rain in the west become more widespread through the morning and afternoon, heaviest in the west and northwest with spot flooding in places. The rain will become lighter and patchier from most places in the evening. Highest afternoon temperatures of 8 to 13 degrees with moderate to fresh south to southwest winds developing.

“Mild and cloudy overnight with further outbreaks of rain at times, easing towards morning. Temperatures will not fall below 10 to 13 degrees with southwesterly winds decreasing light to moderate allowing mist and fog patches to develop.”

The Bank Holiday Monday forecast paints a slightly better pictures: “Mostly cloudy with outbreaks of rain continuing to ease and become patchier through the morning. A good deal of dry weather will develop for the afternoon and evening along with some brighter spells. Highest temperatures of 13 to 16 degrees in a mostly light westerly wind.

Their outlook for the week beyond that says: “Some light rain or drizzle at times but overall a good deal of dry weather with high pressure building.”

They say it will be “mostly dry and rather cloudy” on Monday night overnight, adding, “however, there will be some patchy rain and drizzle at times as well as some limited clearer breaks allowing temperatures to fall between 6 and 11 degrees. Fog will develop too in light westerly breezes.

“Fog patches will clear through the morning [on Tuesday] to leave a largely dry day with just some patchy rain and drizzle at times. Occasional sunny spells will develop, especially for eastern parts later. Highest temperatures of 13 to 15 degrees in light west to southwest winds.

“Staying mostly cloudy overnight [on Tuesday] with occasional patches of light rain and drizzle. Lowest temperatures generally of 8 to 12 degrees in light southwest to west breezes with mist and fog patches developing again,” the forecast continues.

There will be “plenty of cloud with perhaps more in the way of some sunny spells developing” from Wednesday.

“Staying mostly dry with just a few spots of light rain or drizzle. Highest temperatures of 13 to 16 or 17 degrees in light westerly or variable breezes.

“Predominately dry and cloudy [on Thursday] though there will be further patches of light rain and drizzle with the chance of more persistent rain in the north. Highest temperatures of 13 to 16 degrees with light to moderate west to southwest winds, fresher near northern coasts.”

For Friday, Met Éireann says there is “some uncertainty in the details but indications are that it will be another mostly cloudy day with some patchy rain and drizzle at times. Highest temperatures generally of 13 or 14 degrees in light northerly or variable winds.

“High pressure likely becoming more established [next weekend] with largely dry and settled conditions. Turning slightly cooler but brighter,” they added.

Despite this positive note, Met Éireann’s extended range forecast predicts a “low pressure” system will hit Ireland the week after next from November 11.

“Conditions are likely to turn more unsettled compared with the previous two weeks during this period, with rainfall amounts predicted to return close to normal and temperatures close to the average for mid-November,” Met Éireann concluded.
