Rain in the east will clear this morning and will be followed by "brighter, sunnier intervals".
However, there will be showers in the west which will extend countrywide by this afternoon.
A forecaster said: "Some of the showers will be heavy or squally with a risk of hail and isolated thunderstorms.
"Blustery, with fresh and gusty southwesterly winds, continuing strong to near gale in western and northwestern coastal areas this morning, but easing as the day goes on. Highest temperatures of 11 to 14 degrees."
The showers will continue overnight, particularly in western counties, with a continued risk of hail and isolated thunderstorms.
It will be chilly with the mercury dropping to single figure lows of 4 to 7 degrees. Moderate to fresh southwesterly winds will be strong on coasts.
Met Eireann forecaster Siobhan Ryan warned that the outlook for Sunday is not promising either.
She revealed: "A steering low will feed in blustery, thundery showers on Sunday with a risk of hail, most frequent across Atlantic counties, where they will merge into longer spells of rain at times."
"There will be some sunny spells too, with the driest and brightest conditions across the eastern half of Ireland and Dublin."
Highest temperatures will reach just 9 to 12 degrees with moderate to fresh southwesterly winds, strong on Atlantic coasts.
And the week ahead doesn't look much better as the tail end of Hurricane Epsilon is set to bring more blustery heavy showers to our shores.
While Monday will see a temporary respite from the rain and wind with drier and calmer conditions developing but it is set to be unsettled from midweek with further wet and windy spells.
Monday night will be wet and windy as a band of rain lashes the southwest first before moving northeastwards across the country overnight.
There will be lows of of 4 to 7 degrees in light southerly breezes which will increase moderate to fresh as the rain pushes through, veering westerly in Atlantic areas as it clears.
And forecasters are warning of "very windy" conditions on Tuesday as the remnants of Hurricane Epsilon brings "scattered, blustery and heavy showers, thundery at times with a risk of hail."
