Question

Why is air pressure important for weather forecasts ?

Answer 1

High pressure, it's sunny and dry.

Low pressure brings wind, rain, etc.

Think of how air has to move in to try to balance an area of low pressure.  Then that air may be of a different temperature, humidity, etc. which can cause precipitation

Answer 2

Rapidly falling pressure can be a very good indication of falling pressure.   Pressure falling rapidly is something an observer reports and have significance to pilots.  It is relevent because it tells the pilot where he is to the surface....

Answer 3

High pressure is a sinking air mass.  A low pressure or rising air mass is much more likely to generate storms.  It also indicates the direction of rotation around the air mass.  High pressure rotates clockwise in the Northern hemisphere and low pressure rotates cyclonic or counterclockwise.
