Heat and humidity will build across Germany into the middle of the week before a cold front triggers severe weather.
Following a stretch of unseasonably cool weather across Germany last week, temperatures and humidity will rise each day into Wednesday.
High temperatures will reach 30-33 C (86-92 F) from Cologne to Frankfurt, Stuttgart and Munich on Wednesday. The coolest locations will be from Hamburg and Kiel to Berlin, where temperatures will peak between 24-28 C (75-82 F).

Highs in mid-July typically range from 22 C (72 F) in Cologne, Hamburg and Berlin to around 23 C (74 F) in Karlsruhe and Munich.
The increase in humidity combined with periods of sunshine will make it feel even higher than actual temperatures.
Another dramatic shift in the weather is expected on Thursday as a cold front slashes across the country.

Showers and thunderstorms will develop throughout the country with a threat for severe thunderstorms the eastern half of the country.
“Flash flooding will be the greatest threat from these storms,” said AccuWeather Meteorologist Tyler Roys.
“I am particularly worried about areas from near Hamburg to Berlin,” added Roys.

Rainfall amounts in excess of 25 mm (1 inch) per hour are expected, resulting in dangerous flash flooding and widespread travel delays.
Other areas that could see flash flooding and locally damaging winds include Frankfurt, Stuttgart and Munich.
The arrival of these storms will cut into the intense heat and humidity as cooler air settles across the country by Friday.
While temperatures and humidity will decrease, above-normal warmth is expected throughout Germany from Friday into Sunday.
