People can also expect a mix of rainy and sunny conditions this weekend.
Ireland is set for a spell of unsettled weather with "showers most days" next week, according to Met Éireann's forecast.
Before then, however, the Irish meteorological service says Saturday afternoon (21 May) will be largely cloudy though some sunny spells will develop.
While outbreaks of rain and drizzle will continue to extend from the west, most frequent in the west and northwest, there will be a good deal of dry weather elsewhere.
Highest temperatures of 15 to 18 degrees are expected generally in light to moderate winds that will be fresher in the west.
Following this, Saturday night is set to be mild, humid and mostly cloudy with showery outbreaks of rain affecting Connacht and west Ulster.
That said, there will be long dry spells elsewhere with just occasional showers and it will become misty in places with pockets of fog possible.
Temperatures are not expected to fall below 10 or 11 degrees in moderate winds that will be fresh to strong on western and northwestern coasts.
Sunday morning looks like it will generally be cloudy with showers spreading countrywide from the west, turning heavy in the afternoon and evening across Ulster and north Connacht.
However, it will brighten up in the afternoon too with spells of sunshine developing as highest temperatures range from 14 to 18 degrees, warmest towards the east, with light to moderate breezes.
On Monday morning, showers will become widespread, interspersed with bright or sunny spells.
The showers will turn increasingly heavy in the afternoon with possible thundery downpours, particularly in the east.
Conditions are set to feel fresher with highest temperatures of 12 to 15 degrees and a moderate breeze.
Tuesday is forecasted to be another day of showers with some sunny periods.
Highest temperatures of 13 to 16 degrees are expected with best values towards the east coast with a moderate breeze.
Meanwhile, it is to be breezy or windy on Wednesday with showers or longer spells of rain spreading from the Atlantic in a westerly airflow.
While Met Éireann notes it is "uncertain", there may be very gusty conditions at times in western areas.
The forecaster also said variable cloud cover with some sunny spells are expected, along with highs of 13 to 16 degrees.
As for the days after this, the Irish meteorological service's outlook reads:
"Further showers on Thursday with winds moderating, signs of drier weather later in the week.
"Temperatures will rise slightly into the mid-teens."
