Met Eireann three-hour thunderstorm warning for thousands of Irish NOW amid flood fear & ‘steering' jet stream

Warning of lightning damage and spot flooding as possible effects of the weather, the forecasters said: "Isolated thunderstorms moving eastwards."

Once the warning is no longer in effect, Ireland can expect "mainly dry" weather with clear spells for the majority of the night. However, Met Eireann warned that cloud will move into the west and north later in the night, along with some outbreaks of rain. Temperatures will plunge between 6C and 11C before reaching their highest at 22C on Thursday afternoon.

Met Eireann said: "The rain will clear eastwards through the morning, with a mix of sunshine and scattered showers following, a few heavy further north, with the slight chance of an isolated thunderstorm. "The showers will become isolated later. Highest temperatures of 16C to 22C in mostly moderate west to southwest winds, fresher in the northwest and west."

The forecaster said: "Our weather will be fairly unsettled to end the week and over the weekend with spells of rain or showers and it'll be rather windy, indeed unseasonably so on Friday. "While it's likely to be drier early next week with lighter winds, but there'll still be some showers around. "Temperatures will generally be around average for the time of year, though a little below in parts of the west and northwest." Advertisement WHY IS SUMMER SO DISAPPOINTING? Ireland's weather is remaining rather mixed and somewhat disappointing this summer, but Cathal Nolan from Ireland's Weather Channel has explained exactly why we haven't been basking in sunshine. He said: "The weather across the Atlantic is dominated by the NAO phase, which itself is a marker of how two areas of semi permanent pressure centres are behaving (Icelandic Low and Azores High). "When low pressure is prevalent across Iceland with high pressure strong across the Azores, this is known as an NAO+. Which leads to mild wet weather for ourselves. "This is the typical pattern that we experience in winter, with a somewhat greater occurrence of NAO- conditions during summer, but that hasn't been the case over the past two summers." Advertisement JET STREAM 'STEERING' Nolan said this pattern allows jet stream in the mid Atlantic to steer areas of low pressure and cloud our direction, while the rest of the European continent and even the south of England enjoy plenty of sunshine. He continued: "It's been scientifically proven that the AMOC, a key component of the global thermohaline circulation has been weakening and is at its weakest state in over 1,000 years. "This in turn has lead to a cold pool of water south of Greenland and Iceland, which in turn creates a thermal boundary between the cool sea surface temperatures in the subpolar Atlantic while the subtropical Atlantic continues to heat up." Nolan said the thermal boundary becomes for areas of low pressure and acts like a "steering mechanism" for the jet stream. Advertisement This directs areas of cloud and low pressure towards Ireland and northwest Europe while advecting plumes of very hot air northwards across Europe from the African continent. This has lead to the extreme heatwaves we've seen across Portugal, Spain, France, Italy, the Balkans and Greece. Nolan added: "Finally, weakening of the jet stream caused by a reduction in the thermal gradient between the Arctic and subtropical zones in certain other zones across the globe has lead to a weakening of the jet stream, causing it to bend and buckle, meandering more slowest and getting stuck with increasing regularity owing to heat domes and omega blocks in certain locations, while other areas experience cooler, more unsettled conditions." 3 Cavan and Monaghan have been placed under the weather warnings Credit: Met Eireann Advertisement

Summer 2025 begins Saturday: High temperatures and humidity expected across Egypt
The General Authority of Meteorology announced that summer 2025 begins on Saturday, and will last for approximately three months. In its official statement, the authority clarified that the summer season is characterized by stable weather conditions, rising temperatures, and increased humidity levels. Most days of summer will be influenced by the extension of the Indian Monsoon Depression. This low-pressure system carries extremely hot air masses originating from the Arabian Peninsula's desert. As these masses pass over the Mediterranean Sea, they lose some of their heat but pick up water vapor, leading to both higher temperatures and elevated humidity, which makes the air feel even hotter. Summer low-pressure systems The Meteorological Authority noted that while the Indian Monsoon Depression will affect most summer days, there will be periods influenced by the extension of the Mid-Latitude Depression and the Azores High. These systems bring air masses from Southern Europe, passing over the Mediterranean Sea, resulting in temperatures lower than those associated with the Indian Monsoon Depression. Regarding temperature forecasts for summer 2025, the General Authority of Meteorology explained that temperatures will be above normal averages, interspersed with intense heatwaves and high humidity levels. The authority added, 'In past years, we have become accustomed to rainfall during summer in the southern governorates due to the tropical belt.' Friday's weather Friday will see extremely hot weather during the daytime across Greater Cairo, the Nile Delta, South Sinai, and southern parts of the country. Conditions will be mildly cool along the northern coasts. Nights will be moderately warm across most areas.
