They don't. It is the other way around. Cold fronts commonly cause cumulonimbus. Such clouds form when the atmosphere is unstable, meaning that a parcel of air, when given an upward nudge, will continue to rise on its own. A cold front provides that upward nudge to trigger cumulonimbus development.

It really depends on the type of front. There are two types of fronts, warm and cold. Different types of clouds appear at different points as the front passes over head.

do clouds get hot or cold
No. The description of hot and cold air coming together is based on an oversimplified scenario often given by the media. A collision of hot and cold air simply results in a front. Fronts, particularly cold fronts where cold air pushes away warm air, often result in stormy weather, but the nature of those storms depends on other conditions. In the summer cold fronts often bring thunderstorms, which may be severe. If the storms are strong enough and the winds are configured in the right way, then some of them might produce tornadoes.
Cumulonimbus clouds can develop along warm fronts, but are more common along cold fronts.
Cumulonimbus can occur along any type of front but are most common along cold fronts.
Cb or cumulonimbus clouds form at the cold font associated with heavy showers, followed by cumulus (Cu) clouds. A cold front forms when a more dense, warm air mass over a departing cold air mass

Thunderstorms
Cumuliform clouds typically form along or ahead of a cold front. Most cloudiness and precipitation associated with a cold front occur as a relatively narrow band along or just ahead of where the front intersects Earth's surface.
What causes a cumulonimbus cloud is the cold and warm fronts that colided.
Cold weather front have low pressure air and rain/snow/hail/tornadoes and even hurricanes depending on location. Cold fronts bring huge, towering, billowing clouds [Cumulonimbus] that bring thunderstorms. Warm weather fronts bring gentle precipitation and high pressure air. Warm weather fronts also bring sheetlike clouds [Stratus] and wispy clouds [Cirrus] On the other hand, when there is no front, puffy white clouds [Cumulus] come on fair sunny days.
