A status yellow high temperature warning in place for Ireland has been extended by Met Éireann.
The warning, originally due to expire at 9am on Friday, will run for a further 24 hours and will now remain in place until 9am on Saturday.
Under the warning, Met Éireann is predicting hot conditions by day with maximum temperatures between 27 to 30 degrees, and humid nights with temperatures not falling below 15 to 19 degrees.
A status orange warning for high temperatures exceeding 30 degrees meanwhile remains in place for the six counties of Cavan, Monaghan, south Leitrim, Roscommon, Longford and Westmeath, and will expire at 9am on Friday.
Ireland is set for another scorcher today as Met Éireann said the high pressure system causing soaring temperatures is “still in charge”.
Temperatures reached above 30 degrees Celsius at both Mount Dillon, Co Roscommon, and Newport, Co Mayo on Wednesday, officially making it the hottest day of the year so far.
However, this record could soon be topped as Met Éireann said Thursday would be another hot and mostly dry day, with highs between 26 and 30 degrees.
The forecaster has said temperatures as high as 31 or 32 degrees could be possible at “a few locations inland”.
Temperatures reached 30.8°C at Mount Dillon and Newport at 30.0°C making today the warmest day of the year so far😎☀️👇

After Thursday, the weather will stay “very warm” for the rest of the week. While it will not be quite as hot by the weekend, temperatures will remain in the low to mid 20s.
Met Éireann meteorologist, Liz Walsh, said the high pressure system causing the heat will begin to “dislodge” by Friday.
“What we’ve got here is a ‘blocking high’ – the atmosphere is essentially ‘stacked’ with high pressure going all the way up to the top,” she said.
“This makes the high at the surface slow-moving. It’s basically stuck.
“Blocking highs are usually quite difficult to dislodge but it does look as though the gradual dislodging of this high will be getting underway by Friday, but it’s going to be quite a gradual process.”
