Met Eireann have predicted a brief return to sunnier conditions in the coming days - before a big change as an ominous "airflow" is set to hit.
Conditions will improve slightly at the start of next week with some dry spells and sunshine breaking through.
However it will remain cold with temperatures only just in double figures.
Meanwhile as we head into the weekend we can expect further showers and breezy conditions in most areas.
A Met Eireann forecaster said: "A band of showers, some heavy and prolonged will push eastwards across the country this evening and early tonight. A clearance will follow from the west with just some scattered showers, these mainly confined to Atlantic coastal districts. It will turn cold overnight with minimum temperatures of around 2 to 5 degrees in light or moderate southwest winds.
"Saturday looks set to be a bright and fresh day with sunny spells and just a few passing showers. Later on Saturday evening, rain will develop in Atlantic coastal counties. Maximum temperatures of 10 to 12 degrees in moderate southwest breezes.
"Outbreaks of showery rain and breezy conditions will move into the southwest early on Saturday night and spread northeastwards to all regions overnight. Rain will turn heavy bringing a risk of localised flooding. Lowest temperatures of 3 to 7 degrees, coolest in the north. Fresh to strong southeast winds will develop overnight.
"Sunday will have showers or longer spells of rain, with some showers heavy. There will be sunny spells at times too. Quite breezy or windy in places, most likely along western coasts with strong westerly winds. Highest temperatures of 9 to 12 degrees.
"Outbreaks of showery rain will continue overnight on Sunday, with the best of dry and clear periods in the east during the early parts of the night. It will be windy with fresh to strong and gusty northwest winds. Lowest temperatures of 3 to 7 degrees, coolest over Ulster."
And next week will start with some bright spells and sunshine, although it will be cool with highs of just 12C.
But a big change is expected from midweek as a "fresh northwest airflow" will bring cooler weather and some rain.
A forecaster said: "Scattered showers on Monday, most frequent in western and northern counties with good dry spells elsewhere. There will be some sunshine in most regions too. Highest temperatures of 8 to 12 degrees, coolest in the north. Moderate to fresh northwest breezes will ease light through the day. Showers will continue during Monday night. It will turn cold in places with lows of 1 to 5 degrees, coldest in central parts.
"A good deal of dry weather with just well scattered showers, mainly in the north and west, with sunny intervals on Tuesday. Highest temperatures of 8 to 11 degrees in moderate northwest breezes.
"Remaining in a fresh northwest airflow with cool weather and showers for midweek."
