What Happens When a Cold Front Meets a Warm Front?

A cold front advancing on a warmer air mass will force the warm air mass upward (cold air sinks and hot air rises).

The warm air rushes quickly upward causing rapid cooling and condensation of water vapor. In summer, thunderstorms will often accompany fast-rising warm air; in winter, a snowstorm can form.

Once the cold front has pushed its way under the warm air, the surface temperature in that region will drop sharply.
