Biggest change: Saturday, up 4 hPa.
Pressure bottoms out near 1009 hPa this afternoon, and rises after that.
New York sits 27 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 1007 hPa as of 10:00.
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 New York.
About New York
In New York the calendar matters less than the weather map. The monthly averages stay within about 5 hPa of each other all year, which is a very flat curve. The daily weather is what moves the needle. Sharp swings come on roughly 68 days a year, and most of them land between December and March. High pressure is common too: about 113 days a year read above 1020 hPa. In summer the barometer goes quiet, and whole days go by over the harbor with hardly a wobble.

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 New York, which stands 27 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.
