After the passage of a nightly Atlantic front, the next high-pressure system will rapidly build up from the west on Wednesday (midweek). The wind will shift to the west-northwest, bringing in slightly cooler or less warm air masses. The increasing air pressure will provide for gradually improving conditions throughout the day. Fairly sunny conditions are forecast for Thursday and for Friday. Around six to eight hours of sunshine are forecast for both days, and daytime temperatures will begin to rise again. Another extremely powerful and high-reaching high-pressure system is to be expected again at the weekend, expanding over the Alps. This may result in another period of unusually warm weather, especially towards Sunday. Late summer will not give up just yet!
