Between a high-pressure system over Central and Eastern Europe and a low-pressure trough over Western Europe in a southerly flow, with some Saharan dust temporarily mixing into the weather. This will cause the sky to appear milky white, especially on Friday. Numerous thin, high veil clouds will also join in, further dampening the sunshine. Temperatures will remain very high for this time of year, and this will not change on Saturday. On Saturday itself, the Saharan dust is likely to remain, but the high veil clouds will temporarily disappear. These will become more numerous and denser again on Sunday, so that the sunshine will be more strongly dimmed once more. At the same time, temperatures in the mountains will drop slightly again, and this trend will continue at the beginning of the new week. This will not change the generally good weather, which will remain a pleasant mix of sunshine and a few harmless clouds.
