A low pressure system was set to move from France into southwest Germany on Tuesday, bringing storms, rain and hail, spreading across the country on Wednesday. Meanwhile, air coming down from the North Sea will bring cooler temperatures across the country in the second half of the week, DWD meteorologist Helmut Malewski said in a statement.
Tuesday afternoon will remain sunny in much of the country. But after a warm afternoon, heavier clouds would gather in the south and southwest in the evening, bringing the first storms. The east of the country will be only partially cloudy. Temperatures will drop to 21 degrees in the southwest and 11 degrees in the far north overnight, Malewski said.
Wednesday will be warm but stormy. Residents of the southeast will see sunshine but otherwise, Germany will be dominated by thick cloud and storms, including squalls and even hail. High temperatures will reach 30 degrees in the east and southeast, and between 20 and 24 degrees in the west.
There is a threat of strong winds, even reaching gale force levels at times in the north.
Wednesday night will be cloudy with long rainy periods in the east and southeast, though the west will be comparatively dry. Overnight lows will get down to 17 degrees in the east and 10 degrees in the west.
Rain will persist in the north on Thursday, sometimes falling heavily. The alpine regions will be similarly wet. Otherwise conditions will remain cloudy but with only isolated showers. High temperatures will range from 17 to 22 degrees. Westerly winds will be light to moderate but stronger, stormy winds can be expected in the north, on the coasts and in the central mountain areas.
Overnight lows will drop to between 10 and 14 degrees.
Friday, clouds will remain early in the day to the north of the central highlands but break up in the afternoon. For the rest of the country the cloud cover will be scattered with sunny spells and little or no rain. Highs on Friday will range from 18 to 22 degrees before dropping to between nine and 13 degrees overnight.
