Which severe weather conditions are typically associated with squall lines?

Squall lines are often associated with severe weather conditions characterized by high winds and hail, making this choice the best representation of their typical impact. A squall line is a line of severe thunderstorms that can stretch over hundreds of miles and is usually found ahead of a cold front. As these storms develop, they are capable of producing intense winds, which can lead to damaging gusts that significantly affect the area they pass through. In addition to high winds, squall lines can also generate hail due to the presence of strong updrafts within the thunderstorm, allowing ice particles to grow larger before falling to the ground.

The other choices do not accurately describe the conditions that are typically associated with squall lines. Slow-moving warm fronts and fast-moving occluded fronts are not inherently linked to squall lines; they typically represent different types of weather systems. Cumulus cloud formations indicate relatively stable weather conditions and do not typically pertain to the severe nature of squall lines, which are characterized by their intense thunderstorms and associated hazards.
