Dry in most parts today, with long spells of sunshine, sunniest across the eastern half of the country. However, cloud will increase from the Atlantic and some scattered showers will develop over parts of west Munster and west Connacht later, some possibly turning heavy and thundery.
Very warm and humid, with top temperatures of 20 to 26 degrees Celsius (warmest across the midlands and west). Winds will be mainly moderate southeasterly, breezy at times along south facing coasts.
Showers in the west and southwest will merge to longer spells of heavy thundery rain tonight - spot flooding is likely along with treacherous driving conditions. Heavy rain will gradually push further inland, with mist and fog setting in also. Much of the east and northeast should however stay dry under broken cloud.
Warm and close, with lowest temperatures of 13 to 17 degrees Celsius. Winds will be mostly light southeasterly, but fresh along west and southwest coasts.
