The collision of air masses, also known as fronts, creates a thunderstorm.
This is because, when two large masses of warm, moist air collide, one of them is forced upwards. As it rises, it cools, causing the water vapour to condense into clouds. If the updraft continues, the cloud mass will expand, continuing to rise up into the troposphere, and causing the formation of large raindrops or ice crystals. These then become too large and fall back down at high speed, dragging the air with them, thus creating a massive downdraft, which then results in powerful, gusting winds.
They form a "weather front" along the boundary. This can be a warm or cold front, and in some cases is called a stationary front when the boundary does not change appreciably but air moves along both sides.
The Cold Air mass subsides beneath the Warm Air mass, while the Warm Air mass is elevated by the Cold Air mass.
The cooler Air Mass [is or] becomes subsided, and is also somewhat compressed, as it is forced to 'pass' underneath it. Warm Air Supersedes - in terms of preference for Altitude - Cold Air.
You get a front, which can become a focus for unsettled weather.
a powerful storm!

when two air masses collide it will produce weather changes such as wind, clouds, rain , snow, or tornadoes

The atmosphere moves in masses. When two masses collide they are called fronts. When a cold air mass goes into the land occupied by a warm mass it makes a cold front. The opposite makes a warm mass.
When two different air masses collide they form a cloud.

i think that the air masses change.

It makes a weather front.
