Tuesday will be largely an echo of Monday, though with top temperatures a little lower, at 10 to 13 degrees.
It is expected to be dry across most areas on Wednesday with sunny spells. Some showers will develop over Ulster and northeast Leinster, says Met Éireann. Temperatures are nudging slightly lower, with maximums of 9 to 12 degrees.
A generally dry and bright Thursday will see some rain develop in the northwest during the afternoon before spreading slowly southeastwards during the evening and night. Temperatures could reach 14 degrees.
The rain is due to linger on Friday, which Met Éireann says will be mostly cloudy. It predicts outbreaks of rain over Munster, Leinster and east Ulster, with the west getting the best of the sunshine. In light breezes, the highest temperatures are expected to be between 10 and 13 degrees.
Looking farther ahead, the forecaster says it could turn more unsettled during the second week of May with more frequent spells of rain. Temperatures should sit at about normal for this time of year, it says.
