Ireland will see an end to the current spell of sunshine today as clear skies become miserable as ‘torrential downpours’ spread across the country.
Met Eireann has predicted flash flooding in some places as thunderstorms and “intense lightning” develop into the evening. However, temperatures will remain high.
A forecaster said: “a warm night with another hot day ahead. Temperatures rising up to 30c again today, but thunderstorms are expected to develop this evening and tonight with a risk of torrential downpours and local flash flooding.”
It looks as though this week may not be the last of the summer weather as an expert pinpointed a possible return date for high temperatures.
They said: “Weather models show a chance, just a chance, of warm settled weather returning around the 21st. Wait and see for now, but could this summer have one last blast?”
Meanwhile, conditions will remain predominantly dry this morning, with hazy sunshine. It will be another hot day, especially in Munster and south Leinster, with temperatures generally reaching between 24 to 30 degrees, cooler though in the northwest, and in some other coastal areas where coastal fog may linger, and in some spots, sea breezes will develop.
Otherwise, winds will be light northerly or variable. While a few isolated heavy showers or thunderstorms may develop throughout the day, they will gradually increase in coverage through the late afternoon and evening. The most intense, slow-moving deluges will cause some spot flooding, intense lightning, and a slight chance of hail.
Scattered heavy showers and thunderstorms will continue overnight and at times merging to longer spells of rain, with local deluges and spot flooding possible.
Remaining warm and humid with temperatures dropping to between 11 and 13 in Ulster and north Connacht, generally staying above 14 to 17 degrees elsewhere in light northerly or variable winds.
On Monday, scattered showers and thunderstorms will continue to affect the southern half of the country primarily, becoming intense through the afternoon with an enhanced risk of flooding. It will be fresher but drier further north with just isolated showers and intermittent sunny spells.
Highest temperatures will return closer to average, ranging from a cool 14 to 16 degrees in the north and northwest to between 17 and 23 degrees elsewhere, while light to moderate northerly winds will freshen near Atlantic coasts.
Showers will gradually die out in the south to leave a mainly dry night with clear spells. Lowest temperatures of 10 to 15 degrees, remaining warmest near the east coast in a moderate northerly breeze, fresh at times near northward facing coasts.
Cooler and cloudier on Tuesday with scattered light showers.
Highest temperatures of 15 to 19 degrees, mildest in the south, in moderate to fresh northerly breezes.
Showers will die out early in the night, leaving a dry night with a mix of cloud and clear spells. Lowest temperatures of 8 to 13 degrees in moderate northerly breezes.
A dry day with a mix of cloud and sunny spells on Wednesday in the morning and widespread hazy sunshine developing in the afternoon. Highest temperatures of 15 to 20 degrees, warmest along the south coast in mostly light northwesterly breezes.
Clear spells early in the night, cloud will increase from the west with rain spreading into Atlantic coastal counties towards morning.
Lowest temperatures of 8 to 14 degrees, mildest in the west, as light westerly breezes back southerly through the night.
A band of rain, which may turn heavy at times, will cross the country through Thursday morning, followed by scattered showers through the afternoon, clearing to more widespread sunny spells in the west through the evening.
Highest temperatures of 16 to 22, warmest in Munster, with moderate southerly breezes veering westerly through the afternoon.
While confidence is still quite low towards next weekend, current indications suggest it will turn milder and more settled for a time.
