Which conditions are high air pressure systems usually associated with

Clear, dry weather.

Low air pressure system is associated with air that rises high in the atmosphere (which becomes colder and converted into water vapours). This results in wet and cloudy conditions.

On the contrary, high air pressure system is linked to settled air that does not rise high in the atmosphere. This brings clear and dry conditions as no condensation and precipitation occurs in this case.
