The current heatwave shows little sign of ending, with forecasters predicting more hot weather across Ireland before any widespread rain is expected to arrive.
According to Kenneth from the Donegal Weather Channel, the hottest spell of the current heatwave will run from Wednesday, July 15, to Friday, July 17.
He said temperatures are expected to "widely reach the mid to high 20s, with some inland areas potentially reaching the low 30s."
Coastal areas in the north are expected to stay slightly cooler between Friday and Sunday, with daytime temperatures generally ranging from 18C to 22C.
Elsewhere, much of the country will continue to enjoy temperatures in the mid-20s before a slight cooling trend arrives next week, when highs are expected to settle into the low to mid-20s.
As for when Ireland could finally see some meaningful rainfall, Kenneth said current forecast models point towards Friday, July 24, although there is still plenty of uncertainty.
"Based on the latest ECMWF guidance, the first meaningful chance of more widespread rain currently appears to be around Friday 24th July. However, confidence is low at this range, and it would not be surprising to see that rainfall pushed back further as newer model runs become available."
Today will be mostly dry, sunny and very warm☀️.
A few isolated light showers may develop in the southwest, most likely during the late morning🌦️.

There is also a chance the heatwave could continue beyond next week.
The dry conditions have already prompted Uisce Éireann to introduce a hosepipe ban from midnight on Thursday, July 16. The restrictions are expected to remain in place for six weeks, until at least August 26, as reservoirs continue to come under pressure.
Kenneth explained that both the latest GFS and ECMWF weather models suggest high pressure may rebuild to the northwest of Ireland, allowing very warm air from continental Europe to return.
"Under this scenario, temperatures would once again climb into the mid to high 20s, with some of the warmest conditions across western and northwestern counties. There is a reasonable chance that this pattern could develop, potentially allowing the warm spell to continue towards the end of July."
He added that forecast confidence remains moderate to high over the next seven days, but becomes lower beyond that as small changes in weather patterns could determine how long the heat lasts.
Meanwhile, Met Éireann is forecasting another spell of very warm weather over the coming days.
Today will be mostly dry, sunny and very warm, with only the chance of a few isolated light showers in the southwest. Temperatures are expected to reach 23C to 30C, although eastern coastal areas will be slightly cooler due to light easterly breezes.
Tonight will remain dry and mild, with clear spells and temperatures dropping to between 13C and 17C.
Thursday is also expected to be very warm and largely sunny. While a few isolated showers are possible in the southwest, most areas will stay dry. Temperatures will again climb to 24C to 30C, with slightly cooler conditions along some northern coasts because of a light to moderate northeasterly breeze and the possibility of coastal fog.
