Warm fronts are not the only kind of fronts.
There are also cold fronts and stationary fronts.

Cold Front
A warm front changes weather slowly.
Cold fronts change weather quickly.

A cold front forms when a moving cold air mass pushes against a warm air mass.

The moving cold front “scoops up” warm air as it meets. It lifts the warm air high into the atmosphere.

The warm air cools, and condenses. Tall storm clouds form.

Strong winds blow.

But the rain or snow only lasts for a few hours. A short time after the cold front passes, the weather becomes clearer and dryer.

The temperature drops suddenly.In the winter, a cold front may bring very cold air.

Stationary FrontSometimes a cold air mass and a warm air mass meet, but then stop moving.
The boundary between air masses that have stopped moving is called a stationary front.

A stationary front may remain only for a short time. Then there is little weather change. If a stationary front remains for a long time, the weather changes.

Warm front-like weather takes over. There is a steady rain.The rain may last a few days, then the sky clears and it becomes warmer.
