What causes that terrifying shelf cloud before a storm? It's a low, wedge-shaped cloud formation, often immense. These clouds form at the leading edge of a thunderstorm's outflow. Cooler, dense air from the storm's downdraft spreads outward. This cold air forces warm, moist air upward rapidly. As the warm air rises, it condenses into the visible shelf. They often look menacing, but don't produce tornadoes themselves. Have you ever seen a dramatic shelf cloud like this? This short explores “Fast, Visual Weather Explanations” with clear, visual steps so you can grasp it at a glance. Rewatch to catch tiny details, save for later, and share with someone who’ll enjoy it.
