Saturday's weather: Highest temperatures will be between 11 to 14 degrees
Met Éireann has issued a status yellow weather advisory for Wexford, Wicklow, Cork and Waterford.
There is a risk of some heavy and thundery rain in those areas tonight and tomorrow morning, which may lead to possible spot flooding, according to the preliminary warning.
Heavy rain is expected this morning over Connacht and Leinster with isolated thunderstorms, but it will be mainly dry and bright over Munster and Ulster.
The rain will clear northwards later in the morning or early afternoon and it will become mainly dry everywhere for a time, with sunny spells.
However, showers will push up from the south later in the afternoon and extend to all areas by evening time.
Highest temperatures will be between 11 to 14 degrees in moderate easterly breezes, becoming southerly later.
Showers will continue overnight with longer spells of rain as well and a risk of thunder.
Southeast winds will be light to moderate, but strong along east and south coasts. Lowest temperatures will range from 5 to 8 degrees.
