Cold fronts occur when a mass of cold air overtakes warm air, leading to various weather changes. As the cold front passes, pressure decreases, temperature drops, and wind direction shifts. The severity of weather depends on the moisture and stability of the warm air. Fast-moving fronts can cause severe storms, while slower fronts result in milder conditions. Indicators of an approaching cold front include cumulus clouds and squalls.
