MET Eireann chiefs have warned low pressure in the Atlantic will begin to dominate Ireland’s weather – as “unsettled” conditions develop this week.
There is a chance of “heavy or thundery downpours” as temperatures plummet.
Met Eireann’s Matthew Martin said: “The weather is going to turn cooler and more unsettled in the coming days as low pressure systems in the Atlantic begin to dominate Ireland’s weather.”
Today will bring a mix of sun and showers with some “heavy or thundery downpours”.
He said: “It’s going to be a generally cloudy start today with showery rain pushing south eastwards over the country.
“A mix of sunny spells and scattered showers will follow for many during the afternoon as the rain clears.
“But the cloud and rain will be slow to clear from the south east today.
“There is a chance of a few heavier thundery downpours in Ulster towards evening time.
“It will be less warm today with highest temperatures of 15C to 19C in moderate to fresh southwest winds.”
Tonight will see “clearer spells and scattered showers”.
Mathew said: “The showers will become largely confined to Atlantic coastal counties overnight though.
“Lowest temperatures tonight of 9C to 12C.”
Tomorrow will bring a mix of “cloudy periods and sunny spells” to start with just a few showers.
The meteorologist said: “Cloud is going to thicken from the southwest during the afternoon tomorrow with rain developing in Munster by evening time.
“Highest temperatures tomorrow of 16 to 21 degrees. Coolest in the north and warmest in the south.”
Tuesday will be a cloudy day but it will be drier.
Matthew said: “Then looking further into next week, it will be rather cloudy on Tuesday with a little patchy rain and drizzle about. But rainfall totals are going to be small.
“A few sunny spells will develop from time to time.
“Highest temperatures will range from 15C in the north on Tuesday to 22C in the south in moderate westerly winds.”
Wednesday will be warm but there will be showers across the country.
He said: “Then Wednesday looks set to be a warm and humid day with bright spells but there will be widespread showers.
“And then a spell of heavier and more persistent rain will spread from the west during the evening on Wednesday.
“Highest temperatures on Wednesday of 17C to 22C.”
Thursday will be a “fresh day” with sunny spells and scattered showers.
Temperatures will vary between 14C and 17C.
