On the left, next to the weather icons, a tendency display is shown which indicates the
barometric pressure trend:

Please note:
The display does not represent the current weather conditions but it is a
forecast of the next 12 to 24 hours.
The calculation of the weather forecast based solely on the barometric
pressure results only in a maximum accuracy of about 70%. This means that
the real weather can be totally different the following day. Since the measured
barometric pressure is only valid for an area with a diameter of about 50km, the
weather can also change quickly. This is especially the case in mountainous
areas and high mountain regions.
This is why you should not rely on the weather forecast of the weather station
but get some information locally, for example when you want to hike the
mountains.
