On Thursday, rain across southern areas will gradually extend into eastern and southern counties, with heavy falls possible.
While there is currently no weather warning in place for Cork, Galway or Kerry, the three counties are also bracing for heavy rain and possible thunderstorms.
Met Éireann is forecasting a particularly unsettled period, with some areas seeing heavy showers and thunderstorms through Thursday and into the weekend.
Friday will bring a mixture of bright spells and scattered showers, some of which could again be heavy and thundery.
The weather is then expected to turn cooler, with temperatures falling from the low 20s experienced in parts of Ireland this week towards the mid-teens over the weekend.
Sunday is expected to be particularly wet, with rain affecting much of the country and becoming heavy and persistent at times.
The unsettled conditions could continue into the early days of next week, with further rain or showers expected.
