According to Met Éireann, this week of weather is going to be quite changeable, though the dry, warm weather is expected to return by the weekend.
Monday - Any overnight rain in the south and southeast will clear early on Monday morning, with a dry and bright start expected in most places. Scattered showers, already prevalent in Atlantic coastal counties, should become more widespread by the afternoon. Some showers are at risk of becoming heavy and even thundery, especially in the west and north. Otherwise, it will be a cool, fresh day, with temperatures from 15 to 19 degrees.
Monday night will see showers becoming more isolated, with long, clear spells forecast. Cloud is expected to increase from the west overnight, though, with showers or more prolonged spells of rain pushing in off the Atlantic to affect much of Connacht and parts of west Ulster and west Munster by morning. Lowest overnight temperatures of 8 to 11 degrees, with winds light to moderate and southerly. These will gradually freshen along Atlantic coasts.
Tuesday - A breezy day expected, with moderate to fresh and gusty south to southwesterly winds. There will be showers, concentrated in the west and north, though these will turn to longer spells by the late morning or early afternoon. They will ease over time, giving way to just scattered showers. The rest of the country will have cloudy periods and the occasional shower, with some bright, sunny spells also. Top daytime temperatures of 16 to 21 degrees.
Tuesday night will see showers becoming isolated and largely confined to the Atlantic coastal fringes early on. This will leave variable cloud amounts and clear intervals. Patchy rain and drizzle will arrive in the southwest overnight and will extend inland over parts of Connacht and Munster by morning. Lowest overnight temperatures of 11 to 14 degrees in light to moderate southerly breezes.
Wednesday - There will be limited bright spells in the east and north of the country at first on Wednesday. These will turn cloudy with patchy outbreaks of rain and drizzle becoming prevalent throughout the country. This rain will be heavy at times, particularly in the west and southwest during the afternoon and evening time. Winds will be light to moderate and southerly in direction, with temperatures ranging from 18 to 21 degrees Celsius.
It will be cloudy, misty, damp and humid overnight on Wednesday, with scattered rain and drizzle expected. Temperatures will be no lower than the mid-teens.
Thursday - Further rain forecast for Thursday, though it should become clear and sunnier in the east and southeast by the afternoon. A warm day expected with temperatures from 20 to 24 degrees, coolest along the Atlantic coast.
Friday - Early indications suggest the warm weather will continue into Friday and the rest of the weekend, with dry, settled weather expected and daytime temperatures to range from the low to mid-twenties.
