It depends on the amount of moisture present. If there is enough the warm air mass, which is usually moister, gets lifted, causing it to cool and the moisture in it to condense.
occlusion, where the cold air mass is forced aloft as the warm air rises over it, creating a mix of warm and cold air.
Thunderstorms can form when a cold air mass interacts with a warm air mass because the warm air is less dense and tends to rise over the cold air. As the warm air rises, it cools and condenses, forming cumulonimbus clouds that can lead to thunderstorms. The rapid upward movement of air and moisture in these conditions can create instability, leading to the development of lightning, thunder, heavy rain, and strong winds.
Warm fronts typically bring steady and prolonged periods of light to moderate rain as warm air moves over cooler air. Short and violent periods of rain are more characteristic of cold fronts due to the rapid lifting of warm, moist air.
Actually, when the warm air mass overtakes the cold air, it is called a warm front. A warm front typically brings gradual changes in weather, such as increasing temperatures, and is often associated with gentle rain or snow.
When a warm air mass meets a cold air mass, the warm air mass is forced to rise over the denser cold air mass. This can lead to the formation of clouds, precipitation, and potentially thunderstorms. The weather can become unstable and conditions may change rapidly as the two air masses interact.
A warm front is generally heavier than a cold front due to the warm air being less dense than cold air. Warm air rises over cold air at a warm front, creating a less steep slope as compared to the lifting of cold air at a cold front.

Rain
One of two things are created when a cold air mass meets a warm air mass. The most common thing that is created is a cold front with the cold are rising over the warm. This can cause a line of rain and storms to break out. The other is the creation of a warm front, which is more like the warm air nudging in under the cold air. This too can create rain but it is usually less turbulent.
Warm air is heated by the sun. Warm air expands and becomes less dense and then the cold air comes in and when the two meet rain and thunderstorms result.
What happens is similar to when a warm air mass meets a cold air mass: the Cold Air Mass is forced to Subside beneath the Warm Air Mass. Thusly the warm air is uplifted, it cools and Rain is formed. When a Warm Air Mass meets a Cold Air Mass, the warm air is [again] forced to Rise above the Cold Air Mass, it cools and Rain is formed.
At a cold front, warm air is forced up and over the cold air mass. This usually results in rain and possibly thunderstorms, which may be severe.
Cold fronts often bring rain because as the denser cold air mass moves into an area, it displaces the warmer air and forces it to rise rapidly. This rising warm air cools and condenses, resulting in cloud formation and precipitation. The intensity of the rain can vary depending on the moisture available in the air.
When warm air meets with cold air, it is called a front. This interaction can lead to the formation of various weather conditions such as rain, thunderstorms, or snow.

When a warm air mass meets a cold air mass, a weather front is formed. This can lead to the creation of various weather conditions such as rain, thunderstorms, or snow, depending on the characteristics of the air masses and the movement of the front.
