Following the severe thunderstorms on August 28, weather conditions in Switzerland stabilized under a strong southwest flow. On Saturday, August 29, conditions were predominantly sunny, with temperatures reaching approximately 24 degrees Celsius in the German-speaking lowlands and up to 28 degrees Celsius in the Engadin region. 

Following this period of stability, a high-pressure area over Central Europe is expected to bring a period of heat and dry conditions, with temperatures in regions such as Western Switzerland and the Engadin reaching up to 30 degrees Celsius. Temperatures are projected to peak at approximately 32 degrees Celsius by Tuesday.

A significant weather shift is forecasted to follow this heat. Starting Tuesday evening and continuing into Wednesday, a cold front approaching from France is expected to trigger heavy thunderstorms, rain, and strong gusts, potentially including storm-force winds, particularly on the northern side of the Alps. This transition will cause a substantial temperature drop; in German-speaking Switzerland, daytime highs are projected to fall from 32 degrees Celsius on Tuesday to around 19 degrees Celsius on Wednesday, a decrease of up to 13 degrees.
