Cumulus clouds cause fair weather, but cumulonimbus on the other hand don't, they cause thunderstorms and severe weather. Cumulus clouds can occur on fair weather days because of areas of rising and sinking air from the surface. This is typical of a conditionally stable atmosphere. Cumulonimbus clouds are the result of frontal lifting, allowing air rising to tap into atmospheric energy and therefore allowing the air to rise on its own without further frontal lifting required.
Areas of low pressure usually have cloudy weather. Sinking motion in high-pressure air masses makes it difficult for air to rise and clouds to form. That's why high pressure usually means good weather.
Cyclones - air cools and clouds form and may cause rainy or stormy weather. Anticyclones - it brings dry and clear weather.
To cause a barometer to rise, high pressure and sinking air must dominate the atmosphere. High pressure occurs when air is sinking and compressing, leading to clear skies and generally fair weather conditions. This sinking air prevents the formation of clouds and causes the barometric pressure to rise.
The weather will be dry and low in humidity.
No, that's high pressure. High pressure has sinking air and fair weather. Low pressure is rising air and usually brings lots of clouds and precipitation.
Sinking air, combines with dry weather and only a few clouds are indicators of a cold front. Cold air is heavier and more dense than warm air.

Generally with high surface pressure, there is sinking air and clear skies. With low surface pressure there is rising air with clouds and precipitation given sufficient moisture.
Sinking motion in high-pressure air masses makes it difficult for air to rise and clouds to form. That's why high pressure usually means good weather.

Higher air pressure

the unequal heating of the earth's surface causes wind (warm air rising and cold air sinking), and evaporation creates clouds.
