Long sunny spells and high summery temperatures are forecast for Tuesday morning, before an unpredictable disturbance zone will brush against our regions in the second half of the day and on Tuesday night. Partly heavy thunderstorms will increasingly occur in these areas. There is a local risk for heavy rain showers, storms and hail. A further high-pressure area will build up on Wednesday; the remains of cloudy conditions will soon be replaced by sunshine. On Thursday and on Friday, the heat will reach another peak. Long sunny spells and possibly record-breaking temperatures with a low risk for thunderstorms are expected.
