Friday will start with low stratus in many valleys, but the sun is likely to break through soon. From midday onwards, cumulus clouds will form, particularly over the mountains, leading to localised showers or isolated brief thunderstorms in the afternoon. Morning temperatures will range from 1 to 8 degrees, with highs of between 18 and 22 degrees.

On Saturday, it will be sunny across most of the country to begin with. During the day, numerous cumulus clouds will form, giving rise to showers and isolated thunderstorms in the afternoon, particularly in the mountains. Morning temperatures will range between 3 and 9 degrees, with maximum temperatures between 18 and 24 degrees.

On Sunday, with a light foehn wind, high cloud cover will move in from the start, which may significantly obscure the sunshine at times. In the afternoon, isolated rain showers are possible, particularly in the Tennengau and southern Flachgau. A moderate southerly foehn wind will pick up in some Alpine valleys. Morning temperatures will range between 2 and 10 degrees, with maximum temperatures between 20 and 26 degrees.

Morning temperatures will range between 6 and 13 degrees, with maximum temperatures between 16 and 20 degrees.
