Ireland will see temperatures climbing through the week with expected values in the high 20s or even rising to 30 degrees or higher by Thursday. It will also be extremely mild and humid which will make for some uncomfortable conditions, especially at night, with temperatures likely to remain above 15 degrees.
The high temperatures will also increase the risk of thunderstorms developing, and currently Thursday is expected to see some in the northwest.
Meteorological Situation
Much of Europe is under a heatwave which will cause temperatures of 40 degrees or higher. A plume of extremely hot air from Europe will move towards Ireland bringing it with hot and humid conditions. The heat will build through the week, with temperatures expected to reach the high twenties and even the low thirties by Thursday. It will become very humid and dewpoint temperatures which give a measure of how humid the air will be could hit the mid-twenties on Thursday afternoon (Figure 1), making for some very uncomfortable conditions.

If we look at the wet bulb potential temperature, values in the high teens or low twenties are expected on Thursday. The wet bulb potential temperature gives an indication of how the atmosphere will impact us in terms of heat stress. Figures like this point to uncomfortable conditions on Thursday.
Maximum temperatures on Thursday are likely to reach 30 degrees or higher in parts of the country (Figure 3). These figures may creep even higher. Once our high-resolution forecast model comes into range for Thursday we will have more confidence for the maximum temperatures.

The hot weather will break on Friday with cooler conditions arriving and temperatures falling back to the low twenties.
Impacts
The hot weather will produce impacts such as uncomfortable conditions during the day and especially by night.
