The barometer will likely register a drop in air pressure as the moist humid air moves into an area. This drop in pressure is due to the warm moist air being less dense than cool dry air, leading to lower pressure readings on the barometer.
When a warm air mass moves into an area where a cold air mass is located, it is called a warm front. This interaction typically leads to gradual warming of the air and can result in prolonged periods of precipitation.

When a warm air mass moves into an area where a cold air mass is located, it can lead to the formation of a warm front. As the warm air rises over the cold air, it cools and condenses, resulting in clouds and potentially precipitation such as rain or snow. This process can also bring about changes in temperature, humidity, and wind direction in the affected area.
As warm dry air moves into an area, it typically indicates stable weather conditions will persist. In this situation, the barometer is likely to show high pressure, leading to clear skies and minimal chances of precipitation.

Yes. You would expect the pressure to drop. A low pressure system consists of rising warm air that swirl around a center. Because the air is rising, it lowers the air pressure pressed on the ground. Because of this the pressure-sensing barometer will read that the air pressure is lower. Lower pressure means rain because the warm rising air makes clouds. Expect the pressure to drop as a storm is a low pressure system. Note that cyclones/hurricanes have even lower pressure.
A warm and dry air mass can make the area over which it moves arid and less humid. This is why deserts have dry air while coastal areas are humid.
When cold air moves into an area, the atmospheric pressure is high because cold air is denser than warm air. When a cold front moves through an area, the pressure always rises.
