Ireland weather latest: High pressure arrives but there's a major twist on the way

Ireland's weather is heating up this week but the high pressure building over the country may be short-lived as weather experts watch a potential cold blast arriving next week.

Met Éireann has indicated that from next weekend, things will be "turning colder with frosty nights and mornings and a chance of fog too."

Meanwhile, Alan O'Reilly from Carlow Weather is also watching the potential temperature dip on weather models. 

He said: "High pressure building later in week and more settled and cooler with risk of fog and frost. Very uncertain what happens after the weekend but weather models show a risk of a brief blast of colder air from East but some models keep it away from Ireland so wait and see for now, in case you see any crazy headlines."

Between now and then, Met Éireann still predicts plenty of unsettled weather despite the high pressure coming our way.

"Rain will extend northeastwards to most areas this morning [Tuesday], with scattered showers in the northwest. Some heavy and thundery bursts are possible, especially in the south, and may cause localised flooding. The rain will gradually clear eastwards through the afternoon and will be followed by brighter spells and scattered showers. Highest temperatures of 7 to 11 degrees with light to moderate south to southwest winds, freshening for a time in Munster.

"Tonight there will be a mix of clear spells and scattered showers. Some will be heavy and there's a chance of hail and thunder. Lowest temperatures of 3 to 8 degrees in a light to moderate south to southwest wind, fresh at times in the southwest."
