ANSWER: Cold front
Explanation:
- When the cold front is passing, winds become gusty and there is a sudden drop in temperature, and heavy rain, sometimes with hail, thunder, and lightning.
- Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.
