Met Éireann has issued a severe thunderstorm warning today, with the risk of local flooding and possible hail today.
The nationwide orange thunderstorm warning is active until 9am, while a separate orange warning for counties Carlow, Kilkenny, Wexford, Wicklow and all six counties in Munster remains in place until 4pm today.
Meanwhile, the UK Met Office has issued a yellow thunderstorm warning for counties Antrim, Armagh, Down, Fermanagh, Tyrone and Derry until midnight tonight.
Met Éireann meteorologist Linda Hughes said there had been “very widespread overnight thunderstorms across the country”.
“All provinces are seeing thunderstorms and fairly slow-moving, intense lightning, and also heavy rains. So really most places seeing thunderstorm activity overnight and into this morning,” she said.
“While the thunderstorms have now subsided in most places, there have been a few in south Leinster in the last few hours. We are developing further this morning and this afternoon so mainly over the south and south east but really up Leinster there are more thunderstorms developing later in the morning and afternoon and possibly into this evening.
Speaking of RTÉ morning ireland, Ms Hughes warned of further heavy rains, intermittent flooding and the possibility of hail, which she says motorists should be extra vigilant about.
“The ground is so dry that rain that falls on it won’t be absorbed but will run off the surface… So for the rest of today, there’s a chance of heavy flooding and slow moving downpours,” she said.
“These thunderstorms also pose a risk of hail. It’s quite a severe thunderstorm so there’s a risk of hail and that’s very dangerous for drivers… So drivers should be really careful when these orange warnings are being issued.”
Ms Hughes added that the thunderstorms marked the end of recent heatwave conditions. She said “typical August temperatures” will return from tomorrow.
The highest temperatures today are in the north and west between 15 and 17 °C and between 18 and 23 °C.
Tonight, showers in the south will gradually subside to leave a mostly dry night with clear spells and lowest temperatures of 10C to 14C, warmest near the east coast.
Met Éireann said tomorrow will be cooler and fairly cloudy with scattered light showers, although many areas will have a dry day. Highest temperatures of 15°C to 19°C are forecast, mildest in the south.
Showers will ease early Tuesday evening leaving a dry night with a mix of clouds, clear spells and lowest temperatures of 8C to 12C.
Met Éireann said Wednesday will be a broadly dry day with a mix of cloud and sunny spells in the morning and more widespread hazy sunshine developing in the afternoon. Highest temperatures of 16°C to 19°C are expected, warmest along the south coast.
There will be clear spells for eastern parts early Wednesday evening, however rain will move in from the west overnight. The lowest temperatures are between 9 °C and 13 °C, mildest in the west.
On Thursday, a sometimes heavy streak of rain will move through the country. Met Éireann said scattered showers would follow throughout the evening, brightening into more widespread solar periods in the west. Maximum temperatures of 16°C to 19°C are forecast.
Cloudbursts and isolated showers are expected on Thursday night. It will be mild with temperatures generally not dropping below 10°C to 13°C.
On Friday, individual showers will gradually subside throughout the day, while a band of rain will approach the west coast later in the day. Maximum temperatures of 15°C to 18°C are forecast.
“Current indications are that the weekend will be variable with occasional rain or showers,” Met Éireann said.
