think of it as diffusion, pressure will take up space and clouds will have less space to develop.
Clouds only form when the air pressure is low.

Well low and high pressure air in the clouds is what's making the thunderstorm. Swirling clouds can make a tornado
Tornadoes form in thunderstorms, which are composed of cumulonimbus clouds. Usually a tornado will form from a wall cloud that develops are the based of the cumulonimbus cloud, and will develop from a funnel cloud that comes out of the wall cloud.

When the barometric pressure rises it means calm fair weather is coming or is already occurring. When the barometric pressure falls it means foul weather is on the way such as rain and storms and clouds.
In most storms, which always includes hail storms, the barometric pressure drops. Which the pressure drops, that would allow clouds to form. The more it drops, the more intense the storm can get.
Changes in the barometric pressure indicate a change in the weather. A rising barometric pressure usually indicates clear, stable weather.

The lower the barometric pressure is in a hurricane, the stronger the wind will be. Hurricanes form over warm ocean water and the lower the pressure is, the more moisture that will be attracted from the water. This warm moisture rises up and forms into clouds and wind, so the more moisture is rising, the stronger the winds will be. If the barometric pressure is high, the moisture can't move up and form clouds and wind.
If you mean what 'goes' up when the rain comes down, then the answer is the barometric pressure. A low pressure cell, which is a chief indicator of a rain storm, occurs when the barometric pressure drops below 30 points. As the storm dissipates, the low pressure cell changes, causing the barometric pressure to rise.
Hi Falling barometric pressure means the atmosphere at the barometer is becoming less heavy. It also generally means a storm of some sort is coming with inclement weather. Here's a link to use for using a barometer and clouds to forecast the weather: http://web2.iadfw.net/danb1/clouds.htm
because low pressure is caused when the air above the land heats up and the molecules in it start to expand . Then the hot air rises and under favourable conditions mixes with water vapour and dust to form clouds which bring rain

tornadoes develop from cumulonimbus clouds.
Low barometric pressure usually indicates that air is flowing upwards. When air moves upwards it cools and the moisture in it may condense to form clouds and possibly produce rain and thunderstorms.
