Of the seven days, Thursday moves most: down 7 hPa.
Pressure bottoms out near 1000 hPa on Friday evening, and rises after that.
Liverpool sits 25 m above sea level, so a barometer in the city reads about 3 hPa lower than the sea-level figure. A home station set to the local reading should show about 1023 hPa as of 16:00.
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 Liverpool.
About Liverpool
A port city near the Irish Sea, Liverpool keeps its barometer moving. Sharp changes come on about 79 days in an average year, with January and November the most active months. Around 47 days a year fall below 1000 hPa, so low readings are a familiar sight. The highest average pressure comes in April and the lowest in November. The city sits low, so a home barometer reads only a few hectopascals below the sea-level figures 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 Liverpool, which stands 25 m above sea level, is in the note above: about 3 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.
