weather front
Storm's leading edge
A weather front is the boundary between two air masses of different temperatures or densities.
When a cold front moves through, cooler air displaces warmer air, often bringing storms.
A warm front does the opposite, typically producing lighter, steadier precipitation.
A cold front is expected to bring thunderstorms tonight.
Meteorologists track fronts to predict weather changes.
