The coming days will be bright, with good sunny spells, but patchy rain and drizzle will also affect much of the country, according to Met Éireann.
Today, Monday, August 26, will be mainly dry with sunny periods, with the best of this in the eastern half of the country.
Cloud will increase in the west, with patchy rain developing along the west and north-west coast during the afternoon and evening. Highest temperatures today will be 17° to 21°, with light to moderate south-west breezes.
Tomorrow, Tuesday, August 27, will be much the same as today, starting dry and sunny in the east, but with rain and drizzle in the west gradually spreading to all areas into the afternoon and early evening.
Highest temperatures tomorrow will range from 16° to 20° or 21° in the east, with light to moderate southerly breezes.
Rain and drizzle will continue into the night, but will clear from western areas as the night goes on. Lowest temperatures on Tuesday night will be 9° to 12°.
Highest temperatures on Wednesday will be 15° to 19° with moderate west to south-west breezes.
Moving to Thursday, August 29, showery rain will develop in the west and north-west, spreading to the east later. This rain will clear later in the day, with sunny spells and a few showers. Highest temperatures will be 16° to 19°, with fresh south to south-west winds.

Met Éireann is also warning that conditions today, Monday, August 26, will be conducive to the spread of potato blight, conditions which will continue tomorrow and tomorrow night.
Conditions for drying will be reasonable at first, but will become poorer as the week progresses, while spraying conditions will be best over today and tomorrow, away from Atlantic coasts, but with conditions deteriorating as the week goes on.
Soil moisture deficits are currently low, with the ground saturated in many areas. There will be some restriction to growth in some well-drained soils in Leinster.
