Scattered showers are on the cards for the next few days, sometimes turning thundering and occasionally punctuated by sunny spells.
With temperatures not set to rise above 18 degrees, it might also be an idea to bring a jacket.
Speaking on RTE Radio One this morning, Met Éireann forecaster Klara Finkele warned of heavy showers and the possibility of thunder today.
Sunny spells will break through as the day continues however, with temperatures ranging from 14-18 degrees.
Ms Finkele predicted that showers will die out this evening, with “clear spells developing, however scattered showers will continue along Atlantic coastal counties.”
Temperatures will fall as low as 6 degrees with a light wind blowing across the country.
Sunday should get off to a good start, seeing mostly dry spells nationwide. This is not set to continue however, as “scattered showers along the west coast will become widespread by midday and could turn heavy or thundery in the afternoon, especially in the West and North.”
Temperatures will again range from 14-18 degrees, with strong breezes expected.
And it’s bad news for participants in Monday’s mini-marathon, with unsettled, wet weather expected throughout the day.
Ms Finkele said: “Monday will be a cloudy and wet day with persistent and heavy rain at times, especially over the south and east.
“It will be a cool day, with top temperatures of 12-15 degrees.”
Tuesday will feature much of the same, with winds strengthening and some sunny spells expected.
