Summer will get into gear. With a westerly current over the Alps this trend will occur slowly but ongoingly. The westerly current will be accompanied by increasingly warmer but also moderately humid air from the Atlantic. Therefore, further clouds will mix with the sun and a risk for showers and thunderstorms is expected around the main Alpine ridge and especially south thereof. This summery though not absolutely stable weather cycle will remain unchanged at the weekend. A strong high from the Mediterranean region will spread across the Alps and bring back summer but not until next week. An inflow of warm air and mostly bright sunshine will result in a new heat wave.
