We will experience slightly variable conditions from Sunday to Tuesday or Wednesday during next week. On one hand, a southern upper-level flow will continue to direct fairly warm air in our direction; on the other hand, the humid and unstable air could also make itself felt through brief showers and thunderstorms. The sun will shine at least intermittently and in certain areas. If we follow the currently best weather model, conditions will become more stable again in the second half of the week, with sunshine prevailing and summery high temperatures. Cooler air masses will have no chance for the time being, even though meteorological autumn has actually already begun.
