The changeable summer weather still provides respite. But intense heat is building over Spain, which in early August can reach Germany with temperatures of up to 40 degrees.
After the recent hot days, summer is showing its pleasant side. In many places the temperature is at a pleasant level, and there are always showers and thunderstorms. But this calmer phase might not last long.
The next heat wave is already approaching the Iberian Peninsula. Maximum expected in Andalusia from 43 to 44 degrees expected. If the overall weather situation develops accordingly, some of this hot air could reach Germany.
Weather conditions could send hot air towards Germany
In early August, similar structures often appear in weather models. An area of high pressure over the Atlantic and further east of Germany will initially provide calm weather conditions. At the same time, air pressure is low over Scandinavia, so even cooler air temporarily reaches the north through the North Sea.
However, the deciding factor will be whether an area of low pressure develops over Spain or over France. In this case, extremely hot air could be transported into central Europe from the southwest. Then we would also be in Germany From 35 to almost 40 degrees possible.
Ensemble forecasts show a clear warming trend
The ensemble’s forecasts support this scenario. In the 16-day trend for Hamburg, the weather at the beginning of the month remains initially changeable. Showers and thunderstorms will temporarily cool things down a bit.
However, then the temperature in model calculations increases significantly again. Even in the north, individual calculations show temperatures of about 1,500 meters above sea level. 20 Grad – a sign that the 30 degree mark may be reached again locally.
This development is even more striking in the west and south of Germany. There are some model runs being simulated there. up to 25 degrees at an altitude of about 1500 meters. Such values can reach the maximum temperatures on earth. from 35 to 40 degrees make it possible.
First a thunderstorm and then perhaps a heatwave next
The weather is expected to remain slightly changeable until the end of July. Showers and thunderstorms continue, while temperatures are slowly rising. If the large-scale weather situation develops as currently forecast, the next heat wave could follow in early August.
According to the current status, in particular, there is a significant heat wave. in the west and south of Germany quite possible. Weather models currently see a probability of around 70 percent. However, whether temperatures actually reach around 40 degrees depends critically on the exact position of high and low pressure areas in the coming days.
