Met Éireann warned Thursday that Ireland will experience very hot and humid conditions with a risk of thunderstorms later in the day [1].
The weather event is significant because it marks a peak in a broader European heatwave that is pushing moist air over the island, creating conditions favorable for severe storms [4].
Gerry Murphy, a senior forecaster at Met Éireann, said the day is going to be very hot [1]. He said temperatures will be in the high 20s [1] and will get over 30°C in parts of the Midlands and in Connacht [1].
Murphy said the oppressive feel of the weather is due to the moisture levels in the atmosphere. "It will feel very humid today as well because the air over Ireland associated with the Europe heatwave has more moisture at this stage," Murphy said [1].
Official warnings have been issued to manage the risks associated with the temperature spike. A high temperature warning has been extended across the country [3]. While some reports suggest the entire island is under alert, other records indicate that the specific thunderstorm alert applies to six counties [3].
The combination of high heat and humidity often leads to atmospheric instability. This instability increases the likelihood of lightning and heavy precipitation as the day progresses, particularly in the regions already experiencing the highest temperatures [1], [2].
Residents in the Midlands and Connacht are advised to take precautions against heat exhaustion, and to monitor local alerts for the developing thunderstorm activity [1], [3].
“Today is going to be very hot.”
The convergence of a continental heatwave and high moisture levels indicates a volatile weather pattern for Ireland. When high temperatures are coupled with humidity, the 'real feel' temperature increases, raising the risk of heat-related health issues and providing the energy necessary for sudden, severe thunderstorms.
