On a surface weather map, how is a cold front characterized?

A cold front on a surface weather map shows where a colder air mass is actively advancing into warmer air and undercutting it, lifting the warm air as the front passes. This wedge of cold air pushing beneath the warmer air drives the lift that often produces clouds and precipitation along or just ahead of the boundary. The map symbol typically uses a line with triangles pointing in the direction of movement, signaling the advancing cold air. You’ll often observe a wind shift, with winds veering from southerly or southeasterly ahead of the front to westerly or northwesterly behind it, and a noticeable drop in temperature after the front passes. These combined features—advancing cold air undercutting warm air, a wind shift, and precipitation—make this description the best fit for the surface representation of a cold front.
