After the scorching heat, there's another scourge: a "flood", a storm and hurricane-force winds!
An article from Slobodna Dalmacija reports on an expected severe weather event affecting Croatia and much of the western Balkans midweek. A strong cold front from the Atlantic is set to collide with very warm and humid air over the Mediterranean, creating conditions for intense weather, heavy rainfall, thunderstorms, and strong wind gusts. The weather change begins on Wednesday, with the most significant impact expected late Wednesday and Thursday. Heavy rain, up to 150–200 liters per square meter in some areas, is anticipated, particularly along the northern Adriatic. The risk of flash floods increases due to repeated storm systems over the same area. After the front passes, significantly colder air from the north will arrive, causing temperatures to drop by 15–20 degrees Celsius within 24 hours. This marks the end of the unusually hot start to September and brings more autumn-like weather. In higher parts of the Alps, stronger snowfall is also expected. The article explains that record-high temperatures over the Mediterranean have created highly unstable atmospheric conditions, leading to the potential for powerful and prolonged storms.
A severe weather system is set to sweep across parts of Central and Eastern Europe, bringing heavy rain, thunderstorms, strong winds, and even the possibility of tornadoes. The event is expected to begin midweek, with the most intense conditions likely to occur late Wednesday and Thursday. The weather pattern, described by meteorological services as a “killer of summer,” marks a dramatic shift from the record heat that has gripped the region this September. The change begins on Wednesday, with the most pronounced effects expected during the evening of Wednesday and into Thursday. The stormy weather will spread across northern Italy and the Alps toward Slovenia, Croatia, and the western Balkans. Croatian authorities have issued warnings for the northern Adriatic, where locally heavy rainfall could exceed 150 to 200 liters per square meter over two days. This level of precipitation poses a risk of flash flooding due to repeated rounds of rain falling over the same areas. One of the key factors contributing to the severity of the weather is the collision between a strong cold front originating from the Atlantic and a warm, moist air mass over the Mediterranean. This creates highly unstable atmospheric conditions, leading to the formation of powerful storms. According to forecasts, the instability is further exacerbated by high humidity levels and significant wind shear at different altitudes. These conditions are ideal for the development of long-lasting, severe thunderstorms. Supercellular thunderstorms, which can produce large hail, damaging winds, and even tornadoes, are not ruled out. The weather disruption is not limited to the Balkans; similar conditions are expected in eastern France, Switzerland, the Balearic Islands, northern and central Italy, Austria, and Slovenia. Heavy rainfall is anticipated along the Ligurian Sea, northern Adriatic, and northwest Balkans, with local totals reaching up to 150–200 millimeters over two days. The cold front will continue moving eastward, while the hottest air mass retreats toward eastern Europe and western Russia. Current forecasts suggest that unsettled and cooler weather could persist in much of Europe through the middle of September. The extreme weather follows a prolonged period of record-breaking heat across the Mediterranean. High temperatures, combined with unusually high moisture levels, have created a very unstable air mass with Convective Available Potential Energy (CAPE) values exceeding 3,000–4,000 J/kg. This, coupled with the arrival of colder air from the north, has led to a sharp drop in temperatures. In some regions, temperatures could fall by 15 to 20 degrees Celsius within 24 hours, marking a sudden end to the hot start to September and ushering in more autumn-like conditions. In higher elevations of the Alps, the first stronger snowfall is expected. Meteorological models show a deep trough forming in upper atmospheric layers above the northern Atlantic, triggering a strong cold front that will move through Western and Central Europe. This front will directly collide with the extremely hot air mass, creating a volatile mix that favors the development of severe thunderstorms. The weather pattern is part of a broader trend of shifting atmospheric conditions. A strong ridge in the upper atmosphere over the northern Atlantic and European continent has finally collapsed, ending the persistent heat dome and allowing cooler air to move in. The second wave of the atmospheric disturbance is separating over southern Europe, creating a low-pressure system that moves across Italy toward the western Balkans and contributes to widespread severe weather activity. Meteorological charts indicate how the cold front will become increasingly pronounced throughout the coming days. While the first week of September started with abnormally high temperatures, often 10 degrees above the long-term average, the middle of the month will see a significant drop. For example, in Ljubljana, temperatures were previously around 35–40°C but are expected to fall by about 15°C within 24 hours. This rapid cooling will lead to substantial changes in the air mass, with notable amounts of rainfall expected on Wednesday and Thursday across the northern Mediterranean. The combination of high humidity, extreme instability, and relatively slow movement of the storms will result in large volumes of rainfall in certain areas. Strong gusts of wind, lightning, and localized flooding are all possible outcomes. In the most favorable conditions, tornadoes cannot be ruled out. As the cold front continues its journey eastward, the contrast between the warm and cold air masses will intensify, potentially leading to further weather disruptions. The transition from summer to autumn is becoming evident, with cooler, more settled conditions expected to take hold in many parts of Europe by the middle of September.

A dramatic weather pattern, referred to by Severe Weather Europe (SWE) as the 'killer of summer,' is forming across Europe this week. This pattern involves a strong trough in the upper atmosphere over the North Atlantic, which will trigger a powerful cold front moving through Western and Central Europe, colliding directly with an extremely hot air mass. The unstable collision will lead to severe weather conditions from the Alps down to the western Balkans, followed by a sharp drop in temperatures. Strong winds, heavy thunderstorms, torrential rain, and locally possible tornadoes are expected. Temperatures, previously around 35–40°C, are projected to fall by 15–20°C within less than 24 hours. This sudden cooling will bring snowfall to higher Alpine areas and introduce fresh autumn conditions across Western and Central Europe.
