Of the seven days, Thursday moves most: down 4 hPa.
Pressure tops out near 1022 hPa tomorrow morning, and falls after that.
Vienna sits 194 m above sea level, so a barometer in the city reads about 23 hPa lower than the sea-level figure. A home station set to the local reading should show about 998 hPa as of 17:00.
The hours already past are the model's record of each hour as it passed, anchored to real observations, though not a reading from an instrument in Vienna.
About Vienna
Vienna's pressure has a settled character. Days averaging above 1020 hPa are common, well over a hundred in a typical year, with the average pressure at its highest in February and its lowest in July. The sharp changes follow the seasons the same way. Sharp day-to-day swings come about 34 times a year, mostly between November and March, while summer months often pass without a single one. The city also stands at about 196 m. That leaves a barometer at home reading roughly 22 hPa below the sea-level figures published here.

Common questions
What is a normal barometric pressure?
Near 1013 hPa at sea level; the exact standard figure, 1013.25 hPa, is the same as 760 mmHg, 29.92 inHg or 101.3 kPa. Anything between roughly 1000 and 1025 hPa is ordinary. Which way it is going matters far more than the number itself.
Why does my own barometer show a different number?
Usually altitude, and sometimes the instrument itself. Weather services correct readings to what they would be at sea level, so that cities can be compared. The figure for Vienna, which stands 194 m above sea level, is in the note above: about 23 hPa below the sea-level reading. If your barometer is already set to sea level and still reads slightly differently, that is the setting on the instrument rather than the weather.
Is a millibar the same as a hectopascal?
Yes. One millibar and one hectopascal are exactly the same amount of pressure, so 1013 mbar and 1013 hPa mean the same thing. The name changed; the number did not.
Does falling pressure mean rain?
Not by itself. Away from the tropics, falling pressure usually means a low is approaching, and lows carry the fronts that bring cloud and rain, so the two often arrive together. But a shallow fall can pass with nothing more than cloud, and rain falls under steady pressure too. The graph tells you a system is on the way, not how wet it will be. The week ahead, just above, shows the rain forecast beside the pressure.
