At the start of the new week, the air will become drier again, even in the lower layers. This will cause the last remnants of high fog to dissipate, and bright sunshine will prevail everywhere from the mountains onwards in a largely cloudless sky. There will be a pleasant mix of sun and clouds towards Tuesday. It will remain slightly cooler than recently, with temperatures staying at a level appropriate for the season for the time being. At the same time, we will remain under high pressure until the middle of the week, so that bright sunshine will prevail again on Wednesday. However, temperatures will rise slightly again. This trend will continue during the second half of the week with a temporarily stronger southerly foehn. Harmless, high cloud fields will repeatedly mark the renewed onset of high-altitude warming. The frost line will rise significantly above 3000 meters above sea level again, and this is unlikely to change much until the middle of the month.
