Much of the country would remain warm and muggy for the next two days, the German Weather Service (DWD) said.
Maximum temperatures were expected to reach between 24 and 30 degrees Celsius Wednesday afternoon, the DWD said. The north and northwest could expect some showers and even storms, along with some higher altitude areas in the south and east.
The west and northwest can also expect showers and storms overnight with storm warnings for some parts. The night will be warm, with lows of between 20 and 14 degrees.
Most of Germany will remain hot on Thursday, and the influence of the low pressure system Doris is expected to bring storms, dumping rain and hail on the west and northwest. Temperatures will range from 22 degrees on the coast to 28 inland. In the south, the mercury is tipped to soar up to about 32 degrees.
On Friday, Doris will move from the west to the east of the country. The east and southeast regions will remain unsettled, while the western half of the country will likely be calmer.
